Piston type primary pressure control valve VP-1 is installed to keep pressure constant in a piping system with a given discharge rate, such as a heavy oil burning system, and developed to replace conventional diaphragm or bellows type primary pressure control valves.
This pressure control valve, which uses a piston at the receiver for detected pressure, has no risk of the pressure receiver being damaged and many excellent features including stable action, fast response, secondary pressure compensation and high accuracy of pressure control.
In addition, low pressure (0.1 to 0.5 MPa)-use primary pressure control valves installed for lubricant pumps are to be manufactured.
