TESTanDRAIN, Model 2511A, Multi-Directional, Includes Pressure Relief Valve - Made in USA
Similar to the model 2500, the Model 2511A TESTanDRAIN® is a 300 PSI rated single handle ball valve that was specifically designed to provide both the test function and the express drain function required for a wet fire sprinkler system. The Model 2511A provides an alternate handle location from the Model 1011A for multi-directional installations. It features a tamper resistant test orifice, integral tamper resistant sight glasses, and a tapped port for system access. The Model 2511A has the added feature of a Model 7000 Pressure Relief Valve with drainage piping. It is designed to relieve excess pressure caused by surges or temperature changes while solving the difficult problem of providing the relief valve with a drainage-piping outlet. The Model 2511A complies with the requirements of NFPA 13 which stipulate a pressure relief valve be installed on all gridded systems and downstream of all pressure reducing valves.
