Piston valve CK2 series

manualstopfor gas

These CK-2 Gas Powered Suction Stop Valves are used on low temperature applications to positively close suction lines and both liquid legs and gas returns on flooded evaporators. These piston type, gas pressure powered, normally open, heavy duty, cast iron bodied valves are built with control valve precision. All are equipped with flanges and manual lift stem. The 32mm (11/4") port size has a PTFE main seat; 40mm (1-5/8”) port and larger have a metal to metal seat. The CK-2 utilizes a spring to open and therefore requires no pressure drop to open. On suction line applications pressure drop is nominal; on flooded evaporators normal gravity circulation is unrestricted. Being pressure powered to close this valve can overcome sticking at low temperatures caused by the presence of viscous oil. Features and Benefits: • Low Pressure Drop • Heavy Return Spring • Use in Vertical or Horizontal Line • Main Valve Can be Installed on Side Applications: • Low temperature applications to positively close suction lines and both liquid legs and gas returns on flooded evaporators
