Series BBV-1 3-Valve Block Manifold

Brand: Dwyer Instruments, LLC

Series BBV-1 Block Manifold can be used over a broad range of industrial applications including oil refineries, nuclear power stations, petrochemical processing, and more.

The Series BBV-1 body is forged from 316 stainless steel bar stock and designed to withstand repeated open and close operations. 

Suited to control oil, water, toxic fluids, chemicals, air, and steam; the 3-valve block manifold has (2) isolate and (1) equalizing valves. Each valve stem is precision machined with hard seats to reduce operating torque.

The flanged model is designed to mount to an industrial differential pressure transmitter. The BBV-1F comes with four 7/16-20 UNF mounting bolts and two PTFE gaskets, and the BBV-1D comes with eight 7/16-26 UNF mounting bolts and four PTFE gaskets.
