Regulating Valves EB45 & EB25

What is a PRV?

A pressure regulating valve (PRV) regulates downstream pressure in residential and commercial water applications. They reduce the incoming water pressure to a steadier pressure on the outlet side, protecting plumbing systems from high water pressures that can cause pipes, fittings and fixtures to leak.

Cash Acme® PRVs are assembled in the USA and are tested for performance in our manufacturing plant prior to shipping.

Codes and Certifications

Cash Acme lead free Water Pressure Regulating Valves are certified to various plumbing standards such as ASSE 1003, ASSE 1061 (SharkBite connection only), CSA B356, NSF/ANSI 372, NSF/ANSI 61, and listed by IAPMO & ASSE for use in accordance with U.S. and Canadian plumbing codes.


Cash Acme EB45 Pressure Regulating Valve


The lead free EB45 valve features a half-cartridge design that offers the performance of a high end cartridge-based valve and the price of a traditional regulator. The half-cartridge is diaphragm-operated and includes an integrated back-pass check feature.

Pressure Ratings

  • Inlet pressures up to 400 psi between sizes 1/2" to 1"
  • Inlet pressures up to 300 psi between sizes 1-1/4" to 2”
  • Inlet pressures up to 200 psi for EB45 with SharkBite® connections


Ideal for replacing existing pressure regulating valves.

The EB45 slip PRV can be quickly installed on an existing pipe by removing up to 2 inches of pipe and using the slip feature to slide the fitting onto the pipe and then using the SharkBite demount clip to slide the fitting back onto the other end of pipe, completing the connection.

SharkBite connections enable installation in wet lines under full flow. This means faster restoration of water service and less downtime on the job.
