Pressure 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.



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

EB45 Slip Pressure Regulation Valve

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.





  • The lead free EB25 valve has a single, full-cartridge design making it easy to service. Incorporated “micro-fingers” eliminate any water whistle or water hammer by dissipating noise as water flows across the valve seat.
  • It is diaphragm-operated with an integrated back-pass check feature, and it also has a self-locking adjustment knob and pressure indicator for easy adjustment and installation.

Pressure Ratings

  • Inlet pressures up to 300 psi
  • Inlet pressures up to 200 psi for EB25 with SharkBite connections

EB25 Multi-Cartridge


The EB25 Multi-Cartridge (MC) is a pressure regulating valve (PRV) designed for high and low flow applications. The accurate flow control and pressure regulation of the multi-cartridge eliminates the need for costly valve installations like parallel system PRVs or automated control valves.


The EB25 Multi-Cartridge (MC) is ideal for commercial or industrial buildings.

Features & Benefits

Convenient orange pressure adjustment twist-cap and numerical indicator allows for quick water pressure adjustment.

CONNECTIONS 2" 2-1/2" 3" 4"
Threaded (FIP)   X X  
ANSI CL 150 Flanged   X X X


Parallel PRV System Installation

The EB25 Multi-Cartridge eliminates the need for costly two-valve installation. One valve to handle high and low flow demands versus two valves.


EB25 Multi-Cartridge Installation

Single-piece cartridges on the EB25 Multi-Cartridge can be removed with the valve body remaining installed on the pipe, making servicing pipes quicker and easier.
