VB9 Unloader Valve With Pressure Switch
PA VB9 trapped pressure unloader valve with a built-in pressure switch, in brass and steel, adjustable from 22 to 220 bar and rated to 30 litres per minute and 90°C. When the trigger gun is released it diverts the water to bypass.
The pressure switch operates at 30 bar and can be wired into a total-stop or delayed shutdown control circuit; the microswitch is rated at 6(2)A, so a contactor or relay may be needed. The valve is not preset and must be adjusted and tested after installation. It has a 3/8" BSP female inlet, 3/8" BSP male outlet, 3/8" BSP female bypass and 1/4" BSP female gauge port.
