In the world of MEP (Mechanical, Electrical & Plumbing) systems, pressure reducing valves (PRVs) play a critical role in maintaining safety and efficiency. But not all PRVs are created equal. When you're dealing with high-pressure environments, the choice between a piston-type PRV and a diaphragm-type PRV can make all the difference.
At Pipeline Products India, we supply only tried, tested, and trusted PRV solutions—and here’s why we recommend piston-type PRVs for demanding applications.
What’s the Difference?
Diaphragm-Type PRVs:
These use a flexible rubber diaphragm to adjust pressure. They're best for low to moderate pressure systems like residential plumbing.
Piston-Type PRVs:
These use a solid metal piston mechanism to control pressure. They're built for high-pressure, high-flow environments like commercial buildings, fire-fighting systems, and industrial setups.
Why Piston-Type PRVs Are Better for High Pressure
-
Stronger Build
Made of brass or stainless steel, piston-type valves can withstand high inlet pressure and tough conditions. -
Higher Pressure Drop Ratios
Piston-type PRVs can handle pressure reduction up to 10:1. Diaphragm PRVs usually max out around 3:1 or 4:1. -
Durability & Longevity
The solid piston design resists wear and tear better than delicate diaphragms, especially in dirty or hard water conditions. -
Smooth Performance
Less vibration, water hammer, and more consistent pressure—ideal for tall buildings and fluctuating loads. -
Low Maintenance
Built to last, piston PRVs require less frequent replacement or repair.
Where They Work Best
-
High-rise residential and commercial buildings
-
Fire protection and sprinkler systems
-
Booster pump and overhead tank systems
-
Industrial steam or water supply lines
-
Hospitals, hotels, and large infrastructure projects
