Pneumatically actuated valves

series MVAA with disc seals

All functions like 3/2 normally close and open, 5/2 monostable and bistable and 5/3 with closed, exhausted and pressured centre position are available. The disc seal allows bidirectional air flow and ensures bidirectional tightness, effectively eliminating the risk of seal deformation by air flow and subsequent piston seizure. This design is generally characterized by the ability to withstand higher pressures compared to standard seal types, however, the working pressure is limited by the design and parameters of other internal parts. Therefore, the prescribed pressure is the same as the standard MVAA series.

This valve series contains rubber gaskets.

The valves of MVAA series can be mounted on manifold. Then it is possible to use one air supply (which can be through) and common exhausts. Manifold assembly can save space and reduce installation and maintenance costs. The manifolds are the same as for valves of MVSC series. Order codes and dimensions can be foundon page with Valves series MVSC with 5/2 and 5/3 functions and on page Valves series MVSC with 3/2 function.
