Check Valve - Spring Close

RFF - Type CR

These valves (sizes 10 to 250ND) have steel valve body for direct connection to pipe work, to prevent reversal of flow of refrigerant in discharge, hot gas, liquid and suction lines.

Available with Angle (CRE) or Straight Through (CRD) body configuration these check valves offer reliable operation regardless of mounting position, however best for the angle type to be vertical to allow the seat weight to aid closing.

Butt Weld connection "S" the most commonly stocked but also available for Brazing "B" for ODS copper tubing sizes (1/2" to 4 1/8"), Socket Weld "K" in sizes (10 to 32ND) and 2mm gauge tube "H" sizes (10 to 250ND).

Suitable for Ammonia, CO2 and other common refrigerants for RFF. Pressure drop for wide open operation between 10 to 20kPa dependant on valve size and position. Refer to RFF Table Spring strength table for check valves, p45.
