Series BBV-2 5-Valve Block and Bleed Manifolds are ideal for use over a broad range
of industrial applications including oil reneries, nuclear power stations, petrochemical
processing, and more. The Series BBV-2 body 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 5-Valve Block and Bleed Manifold
has (2) isolate, (1) equalizing, and (2) vent valves. Each valve stem is precision
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. The BBV-23F comes with eight 7/16-20 UNF mounting bolts and two PTFE
gaskets.
BENEFITS/FEATURES
• High pressure shut-off
• All stainless steel and PTFE wetted materials
• Precision machined hard seats to reduce operating torque
APPLICATIONS
• Industrial gage or transmitter isolation
