Bulletin V-BBV-1 Series BBV-1 Block Manifoldcan 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: ISOLATE (Blue) EQUALIZE (Green) The BBV-1 3-Valve Block Manifold require periodic maintenance. It is recommended to change the sealing gaskets periodically for safety. CAUTION: 1. Do not remove the instrument from BBV-1 3-Valve Block Manifold when the system is under pressure. 2. Do not remove the safety pin provided on the body. 3. Do not use the BBV-1 3-Valve Block Manifold above the recommended working pressure and temperature given in the specifications.
