Yarway 7100 Series ARC® Valve For Centrifugal Pump Protection
A self-contained system, the 7100 Series ARC® valve has a pressure reducing trim and is in-line repairable.
General Description The 7100 Series ARC® Valve has been specifically designed and manufactured to meet the demands and operating philosophies of today’s high pressure centrifugal pumps. Many power plants are now operating under peaking or throttled conditions, which in turn requires the pumps to operate at less than their optimal design and performance levels. As a result, they are subject to serious damage from hydraulic, mechanical and/or thermal abnormalities. The 7100 Series ARC® provides the most economical and reliable system to protect pumps from the dangers of low and/or reverse flow. It combines the functions of a check valve, flow sensing device, minimum flow control and pressure letdown into a single valve. The ARC® valve requires no external use of power and installs easily with only three connections. By eliminating at least seven major interdependent components, that ordinarily would be necessary to provide this protection, we have not only simplified the system, but made it much more reliable. Our quest for ensured pump flow protection does not, however, end at just providing the hardware. We analyze the complete pumping system and piping. Very often the application’s fluid hydraulics and dynamics compromise the effectiveness of the protection system. A thorough analysis of conditions up and downstream of both the pump and ARC® valve will provide us with solutions to “reliable” protection... things such as 1) proper pressure throughout the complete by piping to prevent any level of flashing or cavitation; (a condition that is prevalent in all pressure breakdown systems); 2) improved by manifold arrangements; 3) good piping layouts that promote stable operation; 4) stable and reliable interaction of pump and valve at less than optimal conditions of operation.
Flow Control
The 7100 Series ARC® is made to operate in a low flow condition for extended periods without damage to the valve or by piping system. The need is no longer just for emergency, short duration shut down, but for extended operation at low flows. Our check and by/pressure letdown elements are specifically designed to operate under these difficult conditions. There is no need
for an auxiliary manual by- system which only serves to negate the advantage of an automatic system. The design of the 7100 Series ARC® is the result of 27 years of experience and over nine thousand ARC® valves in service. And to help ensure every valve works properly, functional tests are performed and the valves are then certified for the application.

Yarway 7100 Series ARC® Valve For Centrifugal Pump Protection
Back Pressure Regulator (BPR) line is reduced, the orifice becomes less effective. Proper system design should be used to optimize valve pressure reduction and consider all fluid dynamic effects downstream of any pressure reducing device.
In high pressure pumping applications the system often does not provide adequate pressure in the by line to prevent cavitation or flashing. Either of these conditions is undesirable in that it can cause damage to both valves and the pipe system or cause a reduction in flow beyond the minimum desired, jeopardizing the pump protection system. All PRVs will experience a velocity induced recovery effect which will limit the amount of pressure drop a valve can take and cause a reduction in flow capacity.
When adequate back pressure is not available downstream of a pressure reducing valve, vapor bubbles will form in the zone just downstream of the valve last stage control surface. This zone is defined as the “Vena Contracta” and represents the point of highest fluid velocity and lowest pressure. The potential for 1) damage to downstream piping components and 2) flow reduction exists from this point. When line pressure remains below the fluid vapor pressure, any existing bubbles will remain and expand as piping friction further reduces line pressure. This can be defined as a “FLASHING CONDITION” and is characterized by a polished appearance on affected surfaces. When the line pressure drops below the fluid
The requirement of back pressure is generic to all pressure reducing applications. Pressure reduction even by multiple stage cascading such as in the 7100 Series ARC® can minimize the requirement, however no valve design will redefine a fluid’s physical properties. This becomes especially important in modulating systems. A fixed orifice will not provide the proper back pressure at all flow levels. As the flow in the by
vapor pressure and then recovers, any entrapped vapor bubbles will collapse (implode). This is defined as a “CAVITATING CONDITION” and is characterized by a cinder like appearance on affected surfaces. The resolution of either condition is best addressed by eliminating vapor formation. This can be ensured by the provision of adequate back pressure. The “Backpressure Factor” is key to reliable system operation and must not be ignored in piping design considerations. As such we feel it is the obligation of a responsible Automatic Recirculation Control Valve manufacturer to analyze the system needs and supply a Back Pressure Regulator (BPR) when it is warranted by the laws of fluid dynamics. For on/off systems this could be a simple orifice, but for modulating conditions it must be a device like the BPR noted herein.
Flanged body BPR illustrated (installed between flanges). Wafer BPR is also available.

A self-contained system, the 7100 Series ARC® valve has a pressure reducing trim and is in-line repairable.
General Description The 7100 Series ARC® Valve has been specifically designed and manufactured to meet the demands and operating philosophies of today’s high pressure centrifugal pumps. Many power plants are now operating under peaking or throttled conditions, which in turn requires the pumps to operate at less than their optimal design and performance levels. As a result, they are subject to serious damage from hydraulic, mechanical and/or thermal abnormalities. The 7100 Series ARC® provides the most economical and reliable system to protect pumps from the dangers of low and/or reverse flow. It combines the functions of a check valve, flow sensing device, minimum flow control and pressure letdown into a single valve. The ARC® valve requires no external use of power and installs easily with only three connections. By eliminating at least seven major interdependent components, that ordinarily would be necessary to provide this protection, we have not only simplified the system, but made it much more reliable. Our quest for ensured pump flow protection does not, however, end at just providing the hardware. We analyze the complete pumping system and piping. Very often the application’s fluid hydraulics and dynamics compromise the effectiveness of the protection system. A thorough analysis of conditions up and downstream of both the pump and ARC® valve will provide us with solutions to “reliable” protection... things such as 1) proper pressure throughout the complete by piping to prevent any level of flashing or cavitation; (a condition that is prevalent in all pressure breakdown systems); 2) improved by manifold arrangements; 3) good piping layouts that promote stable operation; 4) stable and reliable interaction of pump and valve at less than optimal conditions of operation.
Flow Control
The 7100 Series ARC® is made to operate in a low flow condition for extended periods without damage to the valve or by piping system. The need is no longer just for emergency, short duration shut down, but for extended operation at low flows. Our check and by/pressure letdown elements are specifically designed to operate under these difficult conditions. There is no need
for an auxiliary manual by- system which only serves to negate the advantage of an automatic system. The design of the 7100 Series ARC® is the result of 27 years of experience and over nine thousand ARC® valves in service. And to help ensure every valve works properly, functional tests are performed and the valves are then certified for the application.

Yarway 7100 Series ARC® Valve For Centrifugal Pump Protection
Back Pressure Regulator (BPR) line is reduced, the orifice becomes less effective. Proper system design should be used to optimize valve pressure reduction and consider all fluid dynamic effects downstream of any pressure reducing device.
In high pressure pumping applications the system often does not provide adequate pressure in the by line to prevent cavitation or flashing. Either of these conditions is undesirable in that it can cause damage to both valves and the pipe system or cause a reduction in flow beyond the minimum desired, jeopardizing the pump protection system. All PRVs will experience a velocity induced recovery effect which will limit the amount of pressure drop a valve can take and cause a reduction in flow capacity.
When adequate back pressure is not available downstream of a pressure reducing valve, vapor bubbles will form in the zone just downstream of the valve last stage control surface. This zone is defined as the “Vena Contracta” and represents the point of highest fluid velocity and lowest pressure. The potential for 1) damage to downstream piping components and 2) flow reduction exists from this point. When line pressure remains below the fluid vapor pressure, any existing bubbles will remain and expand as piping friction further reduces line pressure. This can be defined as a “FLASHING CONDITION” and is characterized by a polished appearance on affected surfaces. When the line pressure drops below the fluid
The requirement of back pressure is generic to all pressure reducing applications. Pressure reduction even by multiple stage cascading such as in the 7100 Series ARC® can minimize the requirement, however no valve design will redefine a fluid’s physical properties. This becomes especially important in modulating systems. A fixed orifice will not provide the proper back pressure at all flow levels. As the flow in the by
vapor pressure and then recovers, any entrapped vapor bubbles will collapse (implode). This is defined as a “CAVITATING CONDITION” and is characterized by a cinder like appearance on affected surfaces. The resolution of either condition is best addressed by eliminating vapor formation. This can be ensured by the provision of adequate back pressure. The “Backpressure Factor” is key to reliable system operation and must not be ignored in piping design considerations. As such we feel it is the obligation of a responsible Automatic Recirculation Control Valve manufacturer to analyze the system needs and supply a Back Pressure Regulator (BPR) when it is warranted by the laws of fluid dynamics. For on/off systems this could be a simple orifice, but for modulating conditions it must be a device like the BPR noted herein.
Flanged body BPR illustrated (installed between flanges). Wafer BPR is also available.
