Seat Valves

The sanitary and flexible design you know and trust in a fractional size. Authorized to carry the 3-A symbol.
Valves are either remotely controlled by means of compressed air or they’re manually or pneumatically actuated. The valve's parts are few, simple, and movable—which results in a very reliable valve with low maintenance cost.
