TESTanDRAIN® Model 1011A with Pressure Relief Valve

The lightweight and compact Model 1011A is a 300 PSI rated single-handle ball valve with a pressure relief valve designed to provide both the test and express drain functions required for a wet fire sprinkler system. The Model 1011A ball valve eliminates the numerous connections required by the traditional assembly loop saving time, space, and money. The TESTanDRAIN Model 1011A features a tamper-resistant test orifice and sight glass, a tapped port for system access, a pressure relief valve, and optional orifices in all specifiable sizes. The Model 1011A is available in 3/4", 1", 1-1/4", 1-1/2", and 2" sizes in both NPT and BSPT. All TESTanDRAIN products can add pressure relief without draining the system and are field repairable without removing the valve from the system.

Made in the USA. UL listed and FM Approved. Thread x Thread Connection (NPT or BSPT).
