About This Product
■Product description
The overpressure protector consists of a spring-loaded piston valve. Under normal pressure conditions, the spring holds the valve open. When the system pressure exceeds the set pressure, the force applied by the spring overcomes and the valve closes. The valve remains closed until the system pressure drops approximately 25% below the set pressure, after which the spring force opens the valve.
Refer to the data sheet for initial settings. To change the setting: Turn the adjustment screw clockwise ⇒ increase the set pressure (or counterclockwise ⇒ decrease the set pressure) Do not use the overpressure protector as a control device.
