Refrigerant Check and Isolation Valves

 

Check Valves- Ck-1

parker refrigeration Clark Johnson Co

The Type CK1 Check Valves prevent backward flow of fluid in refrigerant suction, hot gas or liquid lines.

 

 

  Product Overview

     Specification

Parker’s CK1 check valves provide safe and effective backflow prevention for a variety of refrigeration applications. The gravity closing feature makes these valves ideal for systems that use a VFD or compressor unloading feature to reduce capacity as they can tolerate load fluctuations better than alternative check valve technologies. All CK1 check valves are flanged and have a manual opening stem for manual operation. The 20-32 mm (3/4 - 1-1/4”) port size valves have a PTFE seat; larger valves have a metal to metal seat. A minimum pressure difference of .03 bar (0.5 psi) is required to open the valve.
