The SC suction solenoid for commercial applications was developed as an alternative low pressure drop shut off valve in a wide range of both port and connection sizes.

The R/S Type SC is a pilot operated solenoid. With cartridge (port) sizes available as large as 2- 5/8”, SC solenoids are capable of handling greater flow rates than other commercially available valves for suction applications in a non-flanged design. In addition, this unique design incorporates the same concept of cartridge interchangeability as found in Parker’s popular (S) PORT evaporator pressure regulators. This innovative design actually utilizes the same capacity cartridges (and valve bodies) as those used with the (S)PORT regulator series, as well as the same solenoid actuator, solenoid coil, and splice box coil housing. Capacity cartridges can be changed by simply unscrewing the valves’ four bonnet bolts in order to remove the adapter and cartridge assemblies.
With this flexible line of solenoid valves now supplementing the existing line of (S) PORT regulators having these same characteristics, a single reliable source for all suction line components is now available. This ductile iron-bodied solenoid valve with brazed copper couplings is suitable for most common refrigerants, certain oils and other fluids approved for use in refrigeration. This valve may be opened by means of a manual opening stem for servicing or in case of electrical power failure.

These solenoids are an integrated assembly of (3) three modules:
1) A body containing no moving parts
2) A capacity cartridge, which contains both piston and modulating plug
3) An adapter on which the pilot solenoid is mounted and which incorporates a manual opening stem which bypasses the pilot pressure around
