The Wilkins 1-70XL is a durable, serviceable 1" pressure reducing valve (PRV) designed for residential and light commercial water systems. Built around a replaceable cartridge and robust materials, it delivers smooth pressure control, long service life, and simple in-field repairs.

• Reliable pressure control: Balanced-piston design with factory preset 50 PSI and user-adjustable range from 25–75 PSI for consistent downstream pressure.
• Durable construction: ASTM B584 cast bronze body and bell with stainless steel trim and 300-series stainless steel seat for corrosion resistance.
• Service-friendly cartridge: Unitized, replaceable cartridge and stainless-steel strainer screen simplify maintenance and reduce downtime.
• Lead-free certified: Meets NSF/ANSI/CAN 61 & 372 for low-lead potable water applications and complies with common plumbing codes.
• Installation flexibility: Single-union FNPT connections (threaded x threaded), 5" inlet-to-outlet length, and a 300 PSI pressure rating; may be installed in any orientation.
• Thermal expansion protection: Integral bypass/check prevents pressure buildup from thermal changes in closed systems.
• Performance ratings: Standard temperature rating 140°F and a factory setting that conserves water and reduces system wear.
