This 1 1/2 inch ACV is armed with ArmorTek(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. This pressure relief control valve is designed to permit flow when upstream pressure is above the adjustable setpoint of the control pilot, and throttle toward closed when upstream pressure falls below the adjustable setpoint. When the valve is installed off the main line on the branch of a tee, it serves as a pressure relief control valve. It is normally closed and quickly opens when upstream pressure exceeds the pilot setting, relieving excess pressure. When the valve is located connecting two distribution zones, the valve acts as a pressure sustaining control valve. When the valve is installed on the discharge of a pump, it acts as backpressure control valve. This Classic valve style has a globe body pattern with class 150 flanged end connections, pilot adjustment range of 20-200 psi, configured with Buna elastomers, and test cocks on top ports.
