Features & Benefits:

• High-Range Pressure Adjustment: Provides 15-125 psi adjustment range with sealed cage design for superior corrosion resistance and reliable performance in all applications including below-ground installations.
• Thermal Expansion Protection: Direct acting integral by-pass check valve prevents buildup of excessive system pressure caused by thermal expansion, protecting your plumbing system.
• Balance Piston Design: Enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.
• Integrated Strainer: Built-in strainer ideal for residential and commercial water systems requiring frequent cleaning of sediment and debris, eliminating need for separate component.
