The Piston Design is easy to install and maintain. If the inlet pressure is higher, this valve reduces it to a steady lower outlet pressure not matter the changing flow rate and / or inlet pressure. The design of this valve don't have outside pipes/conduits, allowing a better installation, maintenance and performance by its bigger chamber and straight flow track that provides a big flow.

The Test and Drain Valve (UL Listed) is a type of valve with both a test function and a quick drain function. An essential product for Fire Sprinkler System. Unique three-in-one design for easier installation, save space and easy maintenance.

This UL Test and Drain allows you to easily check and test the flow through the Sight Glass, then an express drain of the flow.
