Parker commercial pressure regulator (S)PORT/(S)PORTII valves are designed with stainless steel bonnet bolts, adjusting stems, and piston and plug assemblies. The result is a regulator designed to withstand the rigorous application environment a low side regulator must endure. Models are available in combinations of connection sizes, port sizes and features as designated by the model code. Unlike some competitive models of low side regulators that utilize high pressure discharge gas as a pilot source, they are piloted with upstream pressure. This eliminates the requirement for hot gas headers, isolation devices, piping, and the labor associated with the installation of other valves. Flare connections from high pressure pilot lines are also eliminated, minimizing sources for prospective leaks. The valves are an integrated assembly of (4) modules: 1) a body, which contains no moving parts, 2) a capacity cartridge, which contains both piston and modulating plug, and defines the port size and onto which the pilot solenoids providing the"S" (shut-off) or"B" (bypass) features are added as required, 4) the bonnet, containing the range spring and adjustment screw, which is set for the value of pressure which the valve is to maintain. The unique modular design allows the regulator to be soldered into the line without disassembly, yet provides full access for disassembly, cleaning and servicing from the top only. Interchangeable capacity cartridges facilitate flow revisions should an undersized or oversized condition be encountered, while pilot adapters can be changed out to add features or even change functions.

• Retrofitting for additional evaporator capacity is simple and requires no pipe line revisions
• The piston and plug assembly can handle reduced flow conditions and controlling down to about 15% of the valve's maximum capacity
• 7/8" OD
• Designed entirely with corrosion resistant materials
• New cooler running coil and open frame coil housing
• New dual VAC age 208/240/60 Hz coil
• Conveniently located access fitting
• Pilot operated for close control at desired set-point
• Excellent regulation at light loads
• Interchangeable capacity cartridges
• Low pressure drop
• Few moving parts
• Long-life stainless steel diaphragms (no bellows to fail)
• Pilot electric shut-off
• All service from the top
• Sweat-in-place without disassembly

Crankcase Pressure Regulating Valve With Pressure Tap 3/8" OD 0/20 psi

• Parker Crankcase Pressure Regulating Valve with Pressure Crankcase Pressure Regulating Valves are designed to prevent overloading of the compressor motor by limiting the crankcase pressure to a predetermined maximum value during and after a defrost cycle or a normal shutdown period. These valves automatically throttle the vapor flow from the evaporator until the compressor can handle the load. Parker Sporlan manufactures five adjustable direct acting models CRO-4 all models respond only to their outlet pressure and modulate to prevent the suction pressure at the compressor from rising above the valve setting. Since these valves are adjustable, the setting may be altered to suit the specific system requirements.,

Parker Brass Charge W Internal Equalizer Type C Thermostatic Expansion Valve, 3/8" x 1/2" OD 1/2 - 1 ton, R12, R134A

• The Parker C-EC-SC Series balance ported thermostatic expansion valves have a brass bar stock body with flare or sweat connections, adjustable superheat, long lasting replaceable power element and accessible internal parts. Each valve is factory tested to ensure positive leak-free performance. The balance port design provides perfect pin and port alignment and prevents pressure drop across the valve from influencing valve operation.
  
  • Also available is the Parker C Series Interchangeable valve. These C Valves are supplied in two components, the thermostatic element and the valve body. The interchangeable nature of this part of the C family makes it ideal for reducing inventory, while increasing valve options.
