Bosch Rexroth Check Valve - Z1S Size 6

More Views

The valve type Z1S is a direct operated check valve in sandwich plate design. It is used for the leakage-free blocking in one direction and allows for free flow in the opposite direction. Its characteristic feature is the check valve installation set made of high-performance plastic. This permanently ensures high leak-tightness even at low operating pressures. In addition, the use of the valve with different hydraulic fluids is facilitated by the lack of internal seals.

The 4X series check valve has a maximum operating pressure of 350 bar and a maximum flow of 40 l/min. Cracking pressures comprise: 0.5, 1.5, 3, and 5.

Some of the features of the check valve include: 

  • Sandwich plate valve.
  • Porting pattern according to ISO 4401.
  • One- and two-channel blocking function.
  • Perfect leak-tightness due to poppet made of highperformance plastic.
  • Corrosion-resistant surface on request.
