Bulletin V-BBV-1
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
7/16-20 UNF bolts and four PTFE gaskets.
INSTALLATION
Refer to the drawing shown above. The connections to the device must
be made accordingly. The BBV-1 3-Valve Block Manifold can be mounted
in any position. The BBV-1 is fitted with color-coded caps for valve
identification:
