Full Product Description

Parker’s Copper Ball Spring Loaded Check Valves are used in refrigeration and air conditioning systems to maintain flow in only one direction. Internal components seat or “check”, preventing flow back through the valve.
Copper Ball Spring Loaded Check Valves can be installed in the following applications:
• In conjunction with filter driers, strainers, or other devices to ensure unidirectional flow
• In conjunction with compressors to prevent liquid refrigerant from flooding back to the inlet
• In system lines to redirect flow to another circuit
Features and Benefits
• Stainless steel ball is contained in a one-piece brass retainer within a copper tube to provide corrosion resistance and durability
• Straight-flow design yields high flow for maximum system performance requiring only approximately 1 psi for opening pressure
• Standard ball valves offer stainless steel-to-brass seating for low refrigerant leakage
• Sweat connections in a variety of sizes provide for easy installation and simplified brazing
• Spring-loaded design for near-horizontal mounting applications
