Gas Powered Suction Stop Valves- Ck-2D

parker refrigeration Clark Johnson Co

The CK-2D valves are employed as a low pressure drop, gas-powered suction stop valve for low temperature evaporators. These valves are used for suction stop and evaporator equalization following a defrost cycle.

 

  Product Overview

     Specification

The CK-2D is based on the same valve body and operational principles as the standard CK-2 valves making for easy field replacements. 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-2D is a pilot operated, dual-position valve. The CK-2D is a normally open valve and will open on power failure. This valve is equipped with a manual opening stem. The Type CK-2D 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 for servicing.
