OverPressure Protector, Adjustable - 910.13

Brand: WIKA Alexander Wiegand SE & Co. KG
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 exerted by the spring is overcome and the valve closes. The valve will remain closed until the system pressure drops approx. 25 % below the closing pressure, where-upon the force of the spring will open the valve.
Features
  • 7 different setting ranges selectable
  • Minimum pressure to 6 psi (0.4 bar)
  • Maximum pressure to 8700 psi (600 bar)
  • Overpressure safe up to 14,500 psi (1000 bar)
  • Vacuum safe
