Description

CS -12 and CS -25 valves bleed air from the compressor head during the first few revolutions, thus reducing motor starting torque requirements. These valves are especially helpful on oil-lube pumps that may be subject to low temperatures and low starting voltages, such as a contractor unit that may sit outside overnight and be connected to a long extension cord.

The CS valve is installed into any convenient port upstream of the tank check valve. Typical installations are into a 1/8” npt port in the check valve or into a port tapped in the head of the pump or into a tee in the discharge line.

With the discharge line at zero pressure the CS valve is open. As the pump starts the air flows out the CS valve to atmosphere and as pump speed and discharge pressure increase the valve snaps shut and stays closed until the end of the pump-up cycle.
Body and piston are brass with stainless steel spring and fluorocarbon o-ring.

Model Size Compressor
CS-12 1/8” 1/2 to 2 HP
CS-25 1/4” 2 to 5 HP
