  • Description

    The Stubbe DHV 712-R pressure relief valve is specifically designed for dosing technology. The valve is used for pressure relief, overflow or bypass, but is also sensitive/accurate enough to be used as an upstream pressure sustaining valve or back pressure regulator. Rated to 10 bar.

    The valve is used in technical processing plants for keeping preset working pressure constant on the primary side. In addition, it has high reproducibility of the set pressure. Pressure setting is possible at any time, including during operation.

     The valve also performs well in vibrating environments, even behind oscillating dosing pumps. It has a high level of operating safety and long service life with constant, low vibration control.

    The internal piston also performs as a non-return valve
