The SERIES BBV-0 2-Valve Block Manifold is perfect for use over a broad range of

industrial applications including oil reneries, nuclear power stations, petrochemical
processing, and more. The Series BBV-0 is forged from 316 stainless steel bar stock
and designed to withstand repeated open and close operations. Suited to control oil,
water, toxic uids, chemicals, air, and steam; the 2-valve block manifold has (1) isolate
and (1) vent valves. Each valve stem is precision machined with hard seats to reduce
operating torque.

The BBV-0F and BBV-0N are designed to mount directly to industrial pressure
transmitters. The BBV-0F comes with two 7/16-20 UNF mounting bolts and one PTFE
gasket.
