A Pressure Reducing Valve (PRV) is an Automatic Control Valve that reduces a greater unregulated intake pressure to a consistent, lower downstream (outlet) pressure regardless of demand and/or upstream (inlet) water pressure changes. A Pressure Reducing Valve maintains a constant setpoint downstream.
You can utilize a High-Pressure Control Valve package set up for pressure-lowering applications to reduce pressure in high-pressure applications. An adjustable pilot valve in conjunction with an orifice controls the throttled position of the main valve (or needle valve). The pilot valve detects changes in downstream (outlet) pressure and reacts quickly when the outlet pressure rises or falls in response to changing demand.
The pilot detects the downstream (outlet) pressure and reacts quickly by adding or removing water from the top of the main valve diaphragm assembly, allowing the valve to reposition and throttle as the outlet pressure varies with flow demand. As the pilot diaphragm continuously regulates the main valve to throttle, open, or close and maintain the desired, preset lower output pressure, it will automatically sense variations in the system’s flow. The primary valve’s throttling action produces the requisite lowered downstream pressure.

Best Pressure Reducing Valves Reviews
1. Model 70XL Water Pressure Reducing Valve
Buy Now on Amazon for US$184.99
Specifications
| Sizes | 3/4″, 1″ |
| Maximum working water pressure | 300 psi |
| Maximum working water temperature | 140°F |
| Reduced pressure range | 25 psi to 75 psi |
| Factory preset | 50 psi |
General Descriptions
It is designed for installation on potable water lines to reduce high inlet pressure to lower outlet pressure and is appropriate for usage where Lead-Free valves are required. Cleaning and maintenance time is cut in half thanks to the unitized replaceable cartridge. The direct-acting integral bypass design avoids thermal expansion from causing excessive system pressure. The balanced piston design allows the regulator to react to variations in system flow demand smoothly and responsively while also protecting against inlet pressure changes.
Typical Installation
Installation requirements will be governed by local codes. The assembly must be installed in accordance with the manufacturer’s instructions and the most recent edition of the Uniform Plumbing Code unless otherwise stated. For testing and maintenance, the assembly must be mounted with enough side clearance.
The Model 70XL can be mounted in any orientation. Specify the “SC” sealed cage option if installed in a pit, vault, or indoors. For large demand changes or where the required pressure reduction is greater than 4 to 1, multiple installations are advised (i.e.: 200 psi inlet reduced to 50 psi outlet). A pressure gauge must be used downstream whenever a reduction valve is modified to ensure proper pressure setting. On the bell housing, do not use the bottom adjustment bolt.
2. Model 500XL Water Pressure Reducing Valve with Integral By-pass Check Valve
Specifications
| Sizes | 1/2″, 3/4″, 1″, 1 1/4″, 1 1/2″, 2″, 2 1/2″, 3″ |
| Maximum working water pressure | Gas |
| Maximum working water temperature | 140° F |
| Reduced pressure range | 25 psi to 75 psi |
| Factory preset (field set 2 1/2” & 3”) | 50 psi |
General Descriptions
The type 500XL is meant to reduce high inlet pressure to a lower outlet pressure on potable water lines. This device is best suited for industrial water lines and commercial water systems because of its large flow capacity. The direct-acting integrated by-pass design eliminates thermal expansion from causing excessive system pressure. The balanced piston design allows the regulator to react to variations in system flow demand in a smooth and responsive manner while also protecting against inlet pressure changes.
Typical Installation
For testing and maintenance, the assembly must be mounted with enough side clearance. The Model 500XL can be fitted anywhere. Specify the “SC” sealed cage option if installed in a pit, vault, or inside the application. For large demand changes or where the required pressure reduction is greater than 4 to 1, multiple installations are advised (i.e.: 200 psi inlet reduced to 50 psi outlet). A pressure gauge must be used downstream whenever a reduction valve is modified to ensure proper pressure setting. On the bell housing, do not use the bottom adjustment bolt.

3. Model ZW209BPEX Pressure Reducing Valves
Specifications
| Threaded Pressure Rating | 400 psi max. |
| Flanged Pressure Rating | ANSI Class 150, 250 psi max. |
| Grooved Pressure Rating | 300 psi max. |
| Pilot Spring Range | 15-150 psi |
| Temperature Rating | Water 33°F to 140°F |
General Descriptions
The Pilot Operated Pressure Reducing Valve with Low Flow Model ZW209BPEX By-pass is used in a variety of applications where high entrance pressures must be reduced to a safe and stable exit pressure. The pilot assembly responds to variations in downstream pressure, allowing the main valve to vary between open and closed positions, ensuring that the downstream set pressure remains constant.
The main valve will seal shut whenever the downstream pressure reaches the pilot setting. The low flow bypass is set to a slightly greater pressure when the main valve closes, allowing it to manage very low flows up to 10 GPM during off-peak demand. (Flows between the bypass and the main valve minimum flow may require an extra bypass.) Additionally, the Model ZW209BPEX includes an epoxy coating for corrosion protection both internally and externally.
Typical Installation
In all circumstances, the ZW209BPEX is not a suitable replacement for a low-flow by-pass. The Typical Installation of valve is widely used in buildings with low flows of 1-15 GPM during off-peak periods. When sizing a pressure-reducing valve, many elements must be addressed, including inlet pressure, exit pressure, and flow rates.
Additional low-flow by-pass valves are sized using a minimum pressure differential of 50 psi between the inlet and set exit pressure. It may be essential to add an additional low flow by-pass valve to the ZW209BPEX installation to compensate for a range of predicted flows below the minimum continuous flow rate in order to generate a smooth seamless flow response. Set the valve you want to open first, 5 psi higher in static downstream set pressure to manage the opening point of the subsequent by-pass valves.
4. Model 500XLHTSTSCYSBR Water Pressure Reducing Valve with Integral By-pass Check Valve

FAQs about Pressure Reducing Valves
Why Should We Have a PRV?
High water pressure in the home plumbing system can lead to leaking water heaters, dripping faucets, banging water pipes, dishwasher and washing machine noise and failure, and leaking water pipes. Water running at a faster rate than is required to meet regular fixture or appliance needs, can be harmful, wasteful, and shorten the life of equipment in homes. Maintaining a predetermined pressure in the house, often 50 pounds per square inch (psi), can help to ensure that the plumbing and appliances in the home run at a safe, moderate, but sufficient pressure.
Where Should the Pressure Regulator Be Installed?
On new installations, the pressure regulator is normally positioned downstream (on the home side) of the water meter, near the house. These may be bought from a home improvement or plumbing supply store and are quite easy to install, making them a do-it-yourself project. You can, however, contact a certified plumbing contractor in your area for an estimate.
How Long Will a Water Pressure Reducing Valve Last?
A water pressure regulator’s life expectancy is typically 10 to 15 years. However, if a regulator is properly maintained, it can fail after three years and still function correctly after 20 years.
Because previously, a malfunctioning water pressure reducing valve was not replaced but cleaned or repaired with an affordable service kit, PRVs have been dubbed “life-of-mortgage” items. Because dirt or foreign matter on the seating area can cause problems, it is designed similarly to the kitchen faucet. Repairing a water pressure-reducing valve is no more difficult than repairing a kitchen faucet.
How Do We Know If Our Pressure Reducing Valve Is Bad?
- Water pressure that is diminishing or fluctuating.
- There is no water pressure.
- Walls that are thumping, slamming, hammering, or shaking.
- High water pressure, leaking faucets, and a toilet that never stops running.
How Do We Check Our Pressure Coming into The House?
The most precise technique is to purchase a pressure gauge and connect it to a hose faucet/bib at your local hardware store. Check the pressure when all other faucets and water-using appliances are turned off to get a baseline reading. In general, the pressure in your home plumbing should be between 30 and 80 psi.
