Bieri Hydraulic Shut-off Valves

Bieri AVM - Shut-off Valve

The Bieri AVM shutoff valve is a bi-directional direct- and manually-operated seated valve for use in manifolds or alone as a cartridge valve, controlling flow in both directions. You can expect leak-free performance as it opens and closes hydraulic lines up to 700 bar. It also can be used as a discharge valve to the fluid tank. The preferred setting of the valve can be locked by the counter nut.
