Description
Valve 7012 is a direct-acting hitch valve. Plug and core guide pipe are welded to increase pressure and leakage protection. Depending on the application, different combinations of casing and sealing materials are available. A Bürkert-specific flange design (SFB) allows the space-saving assembly of valves on a multi-connection plate. The program is supplemented by explosion-proof versions. Push-in fittings can be selected for a flexible hose connection technique. For easy direct attachment to a pneumatic drive, a banjo connection with hollow screw is the ideal solution. An optional manual operation allows quick start-up and optimum maintenance. In combination with a plug according to industry standard form B or DIN EN 17301-803 form C, the valves meet the protection class IP65.
