Gas Powered Suction Stop Valve- CK-6D

*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

The CK-6D operation is based upon the same principle as the R/S CK-5 gas powered stop valve, with the added feature of an internal vent function, allowing for equalizing after defrost through one valve. This heavy duty gas-powered valve is suitable for ammonia and other refrigerants, certain oils and other fluids approved for use in refrigeration. The CK-6D is a pilot operated, dual-position valve. This valve is equipped with a manual opening stem and A2D pressure pilot. The CK-6D is a normally open valve during refrigeration, with both pilot solenoids de-energized. This valve's position will remain unchanged during refrigeration (opened) should power be interrupted to the pilot solenoids during this mode. During defrost, both solenoids are energized which will close the main valve. Should a power failure occur while an evaporator is in defrost, the valve is designed to re-position itself to its internal vent mode. This will slowly bleed the coil pressure down to the suction line pressure. This eliminates the prospect of a "suction shock" condition in the event of a power failure. The Type CK-6D Gas-Powered Valve is furnished with FPT Internal NPT (U.S. Standard Taper Pipe Thread), Socket Weld, Weld Neck or ODS (solders over copper tubing of given diameter) connections. The valve may be easily removed from between the flanges to make servicing a breeze.
