Check Valves- Ck-1

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

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.

RS Valves

RS- Hand Shut- Off/ Expansion Valves

The RS Shut- off/ Expansion Valves were designed and built to maintain reliability both in their seating and back seating functions.

The complete Industrial Refrigeration line of Hand Shut-Off and Expansion Valves with bolt-on bonnets are designed and built to maintain reliability both in their seating and back seating functions. This entire line is supplied with stainless steel stems for maximum corrosion resistance and back seating capability. A unique carbon filled PTFE seat is standard throughout the line, lending durability to the seating surface. In addition, a dual O-ring stem packing design along with a stem packing seal is standard on all valves 1⁄4” thru 12” (Shut- Off) and ¼” thru 2” (Expansion). This innovative design seals both the valve stem and bonnet bore with independent O-rings, which are captured in a carbon PTFE carrier. The addition of the packing provides for backup sealing capability in the unlikely event of an O-ring failure. A packing nut design with either 1⁄4” or 5⁄16” flats provides a generous wrench engagement area, with little likelihood of “rounding” the flats. With the O-ring cartridge used in all valve bonnets, there will typically be no need to loosen the packing nut when opening or closing a valve. In most cases, stem resistance will be negligible, allowing the valve to be easily repositioned.

The extended bonnet is available for globe style valves in the Tee body configuration and in angle style bodies. Valves are available with either hand wheel or seal cap. These caps are exclusive to this series of valves and should not be exchanged with seal caps from other R/S service valves.

• Industrial Refrigeration

Electronic Valve PEV

The PEV series of electronic modulating valves provide enhanced control for industrial refrigeration systems.

The PEV provides precise control of flow for liquid level, expansion, superheat, and temperature control applications. The stainless steel construction helps overcome corrosion problems encountered in harsh environments. The valve’s weld-in feature design reduces potential for connection leaks. This design has a higher working pressure, a greater working temperature range and higher flow capacities than competitive products. These valves provide long-term performance with replaceable internal components.

Market:

• Industrial Refrigeration

• Commercial Refrigeration

Features and Benefits:

• Suitable for ammonia, CO2, R-134a, R-404a, R-410a and other common refrigerants

• Stainless steel construction increases product life cycle

• Lightweight construction

• Cartridge based design simplifies service and eliminates body wear

• Interchangeable with other P-Series offerings

• Works with any 4-20 mA controller

• Bright LED Display

• Password protection prevents tampering

• Alarm notification

• IP67/NEMA 6 rated

• Parker Backup Module (PBM) available

Function and Design:

• The Parker Electronic Valve (PEV) is an electronically controlled valve that modulates the flow of refrigerant in industrial refrigeration applications. Common applications include those where load fluctuations are great such as chilling and cooling applications and where precise control over temperature or humidity is important. The PEV consists of two major components; the electronic actuator and the sealed valve body.

• The actuator is contained in an IP67 (NEMA 6) housing. The valve body is made entirely from stainless steel, designed to resist corrosion, and work in a variety of industrial refrigeration applications. The PEV is powered by 24 VDC and accepts a 4-20 mA control signal. The PEV will modulate the flow of refrigerant by opening and closing based on the control signal input. The actuator is automatically calibrated when power is established. When the 4-20 mA signal comes back in range after being out of range, or when manually requested by the user. At 4 mA the valve will be closed, and at 20 mA the valve will be 100% open, unless the direction has been reversed at the time of setup.

• The PEV is available with an optional Parker Backup Module (PBM) that will place the valve in a user-defined position in the event of a power loss. After the calibration cycle, the PEV actuator will position the valve based on the control signal input.

• The PEV valve is comprised of a stainless steel 52 bar (754 psi) rated housing. The PEV valve is modulated by means of a magnetic coupling. The magnetic coupling drives a screw mechanism which opens and closes the valve plug.

• Industrial Refrigeration

• Liquid Level Control

Modulating Refrigerant Valve

The MVS industrial electronic control valve utilizes electronic controls to regulate both liquid and vapor refrigerant flows.

The MVS electronic control valve provides precise management of flow for a variety of industrial and commercial refrigeration applications. Due to this precise control systems it will run more efficiently and with less charge which reduces operating costs and increases system safety. As an additional benefit the MVS is a normally closed valve which means that it will move to a fully closed position in the event of a power loss. This feature reduces complexity by eliminating the need for an upstream solenoid valve or power backup module.
MVS valves can be applied to manage liquid levels in vessels, liquid injection for compressor cooling, superheat for direct expansion evaporators, brine temperature in chillers, hot gas for defrost, and countless other installations.
