▶ Special Feature 

● Accurate Pressure Control

● Operation is Fully Mechanical without Electric Power Source

● Fast opening for protection of pipe

● Slow shutting to prevent Surge

● Prevent return flow by back pressure

    Model 133-020 consists of Basic Valve(BALEM130) and Pressure 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.  Also, once downstream pressure is higher than inlet pressure close the basic valve in order to prevent the return flow caused by back pressure

    When pressure raise rapidly, valve will open fast and when it drops, closes slow to protect the pipeline by adjusting the speed
