Pressure regulator valves

PRESSURE REGULATOR VALVES

Regulating valves are used to adjust the pressure in high pressure equipment. It can be regulated from zero to the maximum designed for the valve. The water pumped but not used is diverted through the return/bypass port to the tank of drain line, etc. The pressure regulator valves work continuously as an accurate safety valve not allowing it to exceed the regulated presure.

OPERATING MODE

• Automatic pressure regulator: When the water pressure outlet is cut off the pressure goes down to zero and the motor turns idle. Used with a pistol, foot valve, etc.
• Pressure regulator of maximum pressure or overflow valve: When cutting of the water pressure outlet, the pressure is maintained and the motor works continuosly. The regulator works as a limitation pressure valve only. It's used generally when it isn't necessary to cut off the water pressure outlet for example in sewer cleaning. In pneumatic pressure types besides the overflow basic version. They are also without leak loss. On this type the pressure regulator valve is on "without pressure position". The water goes out of the bypass port and at the same time the outlet pressure port is closed and the nozzle hose doesn't leak out.

REGULATING MODE

• Manual: With screw or lever.
• Pneumatic: By pneumatic cylinder operated with regulated compressed air.
