Safety Warning

Full Product Description

The P Series refrigerant regulator, being weld-in, the valves reduce potential for connection leaks and can be entirely serviced from the top. This improved design has a higher working pressure, greater working temperature range, and higher flow capacities than competitive products. These valves provide long-term performance with replaceable internal components. Specially designed wear rings eliminate the need for removal of the body from the line (maintenance-free).
Markets:
• Industrial Refrigeration
• Commercial Refrigeration

Features and Benefits:
• Stainless steel construction increases product life cycle
• Cartridge based design simplifies service and eliminates body wear
• Increased flow capacity enables smaller valve sizing
• Overall weight reduction up to 50% compared to traditional flanged products
• Integral features prevent contaminants from reaching the pilot section of the valve
• Suitable for ammonia, CO2 and halocarbon refrigerants
• Multiple refrigerant capacities and configurations available
• Interchangeable with other P-Series offerings
• Coil options to meet various applications

Application:
• Depending on the specific variation of this valve, the application may include, but is not limited to;
• Evaporator pressure control, temperature control, defrosting, Maximum Cooling, regulating defrost, Crankcase pressure regulation, Liquid Chillers, Low Pressure Drop, Hot Gas Bypass, Load Change Compensation, Reducing liquid or vapor line pressure, any inlet pressure control, Non-Atmospheric relief, Applications with harsh environments
