Keystone Yarway Automatic Recirculation Control Valves The Yarway Automatic Recirculation Control (ARC) Valve provides effective as well as economical protection for centrifugal pumps against the serious damage from overheating or instability that can result from even a few minutes of low flow. By providing recirculation flow to the suction source of the pump the ARC assures a minimum flow for stable pump operation

The gas over oil or pneumatic actuators equipped with a line break valve constantly monitor the pipeline pressure and trigger the actuator to shut the ball valve in the event of an unexpected pressure drop, averting the risk of uncontrolled gas leaks The valves used for this special application have the same technical features as the standard valves with same design characteristics apart from the connections for connecting the impulse pipes.

Special made valves. Designed, calculated, produced and tested according to customers requirements. Produced in ANY metal, from Carbon or Stainless Steel to Corrosion Resistant Alloys or Titanium.
