Model 133-010 consists of Basic Valve(BALEM 130) and Relief Pilot valve(Model 573). It is installed at bypass of the pipe line in order to prevent damage on pipe by discharging high pressured water to atmosphere once the pipe pressure increased higher than the pre-set pressure, and strengthen the maintenance of constant pressure at the inlet pressure within the pre-set pressure. To protect equipment in the pipeline, when pressure raises rapidly, valve will open fast and when valve closes, closes slow to protect surges and can adjust the speed of the opening and closing.
