SBR Series Diaphragm Pressure Relief Valve
The Simtech SBR Series Diaphragm Pressure Relief Valve is designed to protect piping and equipment from pressure changes where a rapid release of excess pressure is required. Prevents pumps from dead heading, over pressurization, pressure surge conditions, and maintains back pressure in closed loop systems. Adjustable screw and lock-nut makes it easy to accurately preset desired relief pressure.
