Quick Closing Valves

BESI Quick Closing Valves are designed with multiple execution release cylinders, which allow operation by manual (pulling wire), pneumatic and hydraulic execution. The BESI Quick Closing Valve can be delivered in various material compositions and with various flange drillings. Sizes range from DN15 to DN200 in standard, up to DN500 is possible on request. The BESI Quick Closing Valve release stations are equipped with a breakable window and emergency hammer.

The cabinets are built according to costumer request and therefore are without limitation of execution handles. As an option, the electrical open/close indication can be part of the release station. The release cylinder are designed for manual as well as pneumatic and hydraulic execution.
