Introducing our premium Reverse Osmosis Pressure Reducing Valve (PRV), an essential component for optimizing your Reverse Osmosis (RO) systems. This high-quality valve is designed to regulate and reduce the water pressure entering your RO or Reverse Osmosis Deionization (RODI) system, ensuring optimal performance and longevity.

The PRV is constructed with an NSF-approved thermoplastic body, guaranteeing durability and reliability. It features standard 1/4 inch quick connect fittings, making installation a breeze and allowing for seamless integration with your existing setup. By controlling high water pressure, this valve protects your RO system from potential damage and enhances its efficiency.

Ideal for both residential and commercial applications, our Reverse Osmosis Pressure Reducing Valve is the perfect solution to maintain the integrity and functionality of your RO system. Invest in this essential component and experience the difference in your water purification process.

Reverse Osmosis Pressure Reducing Valve: PSI

High pressure is tap water pressure over 70 psi - (if you want to know your house pressure, get a inline pressure gauge and inline ball valve). Most homes in the USA have around 55-60 psi. However, you need to install a PRV if your house pressure is greater than 70 psi.

Compact and lightweight with a 2.0 GPM (gallon per minute) high flow rate capacity, this PRV is regulated at 70 psi. Stop your RODI systems constant drain water! Stop cracking your RO system housings!

Get a reverse osmosis pressure reducing valve today to ensure your system is operating in safe conditions. The Reverse Osmosis pressure reducing valve listed here is rated up to 230 psi and up to 104 degrees Fahrenheit.

Reverse Osmosis Pressure Reducing Valve: Dimensions & Weight

  • Height: 4.25"
  • Width: 1.56"
  • Weight: 4 oz

To install, just cut your tap water supply line and connect both tubes to the PRV and you are done! Please see the arrow marked on the body of the PRV as this indicates the directional flow of water.

RO Pressure Reducing Valve FAQs

What are the disadvantages of a pressure reducing valve?

A Reverse Osmosis (RO) pressure reducing valve can restrict water flow, leading to decreased efficiency and slower filtration rates. It may also require regular maintenance to prevent clogging and ensure proper function. Additionally, it can increase the overall complexity and cost of the RO system.

Can water flow backwards through a pressure reducing valve?

No, water cannot flow backwards through a RO pressure reducing valve. These valves are designed to allow water to flow in only one direction, preventing backflow and protecting the RO system from potential damage caused by reverse water pressure.

What PSI is needed for reverse osmosis?

Reverse osmosis systems typically require a minimum water pressure of 70 PSI (pounds per square inch) to function effectively. Optimal performance is usually achieved at around 70 PSI, ensuring efficient filtration and consistent water output. Low pressure can reduce system efficiency and water quality.
