Cash Acme EB45 Pressure Regulating Valve 3/4 in - Tamper-Resistant 60

In this review of the Cash Acme EB45 pressure regulating valve the bottom line is simple: this is a compact, reliable pressure regulator best suited to plumbers, building maintenance teams and homeowners who need a durable, easy-to-install device to hold downstream pressure steady. The reviewer found the valve's tamper-resistant EB45 design and tool-free connection to be the single biggest reason to buy, since it locks the desired pressure in place and speeds installation without soldering or threaded unions. It is especially useful where potable water compliance and corrosion resistance matter.

Key Features

• Tamper-resistant EB45 design: locks the set pressure to prevent accidental adjustment and maintain consistent downstream pressure.
• Quick tool-free installation: stainless steel teeth and an O-ring compress for a secure, leak-free seal when pipe is simply inserted.
• Durable materials: brass and stainless steel construction resists corrosion and meets NSF/ANSI 372 requirements for potable water.
• Adjustable pressure range: factory-rated to 60 PSI and adjustable from 10 to 70 PSI to suit a range of plumbing systems.
• Hot and cold service capable: supports water up to 180 degrees F, making it suitable for both residential and light commercial use.

Who It's For

The Cash Acme EB45 is aimed at professional plumbers, facilities managers and DIY-savvy homeowners who want a compact pressure regulator that installs quickly and complies with drinking water standards. The unit's tamper-resistant feature makes it a good fit for multi-family or commercial settings where locked settings prevent unintended changes.

It is not the best choice for systems requiring union-style field serviceability or where a non-union full-port regulator is already preferred. Also, buyers sensitive to occasional operational noise should be aware some users report a thumping sound under flow.

Pros & Cons
