Union bonnet tandem valves isolate instrumentation lines

B1 union bonnet tandem valves are used as primary isolation valves for instrumentation lines where highest requirements are placed on the safety of the shut-off function.

B1's tandem arrangement offers safety when workers perform service work on pipe assemblies - especially with media are under high pressure/temperature, or with hazardous media.

Models comprise two separate independent union bonnet valves in a single body. Valve head units are flange-mounted to the valve body with a union nut. Bore size on the valve seat is 11 mm. The sealing to atmosphere is performed by the nonrotating valve stem. This achieves a low actuating moment, reduces load on the sealing, and increases service life.
