New double stage roll-over valve with residual pressure function

Z-V 0010 0631

Our new light weight double stage roll-over valve with residual pressure function has a total length of 93 mm, weights 65 g only and responses faster than comparable products. This valve consists of a PVDF and a stainless steel ball and is known for reliable, bubble-tight sealing. Furthermore a piston ensures a defined residual pressure of the valve.  Thus, this valve is a great choice for fuel applications where tight shutoff and an additionally defined residual pressure function are necessary.

The key features are:

  • Double stage pressure valve for venting the vehicle tank
    Defined residual pressure (opening pressure of residual pressure function at 50±10 mbar)
    Overpressure function (in closed condition, the valve opens between 150-200 mbar)
  • Function according to FIA Appendix J Article 253 (3.4)
  • Ventilation via integrated umbrella membrane
  • Prevents accidental spillage of fuel
  • Prevents the tank from overflowing via the float ball
  • Installation in vertical position only
  • Seal material FKM BF750, FVMQ (E85 applicable)
  • Compact size and light weight
  • Other connection types or alternative opening pressure settings available on request
