● Sensitive and Accurate Pressure Control
● Fast opening to maintain Line pressure
● Slow Closing to prevent Surge
● Ability to anticipate high pressure wave
Model 133-040 consists of Basic Valve(BALEM 130), Pressure Relief Pilot Valve(Model 573) and Pressure Reducing Pilot Valve(Model 562). The valve is installed at Bypass line for protecing pumps and pipe-line systems from dangerous surges caused by rapid chagnes of flow velocity within a pipeline.
The valve has anticipated the down pressure caused by the abrupt stopping of the pump and opening, closing of valve, immediately opens to prevent high pressure in Pipeline and has set to minimize high pressure, relieves excessive setting pressure
