Double Union PRV4 Lead Free Brass Pressure Reducer by Aqualine

Product Description

The PRV4 Pressure Regulator from Aqualine is lead free brass construction. Has brass or durable PVC bonnet and stainless steel nuts and bolts. Double union connections. This item is rated for constant (static) pressure and will reduce the pressure in your system to the desired PSI. Unit is adjustable from 25 - 75 PSI and factory preset at 50 PSI.

Installation Tips: 

  • Flush dirt and scale from supply pipe
  • Install regulator vertically or horizontally (upright or inverted), but the regulator must be installed with the arrow in the direction of flow
  • Regulator is preset at 50 PSI. To adjust, loosen lock nut and turn adjusting screw clockwise to increase, counterclockwise to decrease, then re-tighten lock nut
  • This regulator has a built-in thermal expansion bypass. If the inlet pressure is higher than the discharge setting of the water heater (typically 150 PSI) or if there is a check valve or backflow preventer installed on the line, you must make provisions for pressure relief protection to protect your plumbing system and its components
  • Should be installed in an accessible location

Maintenance Tips:

  • To clean strainer or replace seat/stem module shut-off supply, loosen locknut and back off adjusting screw
  • Replace module and reassemble valve
  • Re-adjust pressure setting
