Dwyer Instruments' Model BBV-2 Block and Bleed Manifold features five valves
W.E. Anderson Division of Dwyer Instruments announces the release of its Model BBV-2 Block and Bleed Manifold. The Model BBV-2 body is forged from bar stock 316 stainless steel and designed to withstand repeated open and close operations. Suited to control oil, water, toxic fluids, chemicals, air and steam, the five-valve block and bleed manifold has (2) isolate, (1) equalizing and (2) vent valves. Each valve stem is machined with hard seats to reduce operating torque.
Flanged models are designed to mount to an industrial differential pressure transmitter. The BBV-21F and BBV-22F come with four 7/16-20 UNF mounting bolts and two PTFE gaskets.
