Series BB-100 OS&Y Gauge Valves

Series BB-100 Isolation ValvesThe Series BB-100 OS&Y Gauge Valves are forged Steel O.S. & Y Bolted Bonnet Offset style gauge valve.  They have a Forged Yoke and a separate Follower Packing Gland to compress the Stem Packing. This design places the thread portion of the Valve Stem outside of the valve body to prevent contact with the process fluid. The Valve Stem is a non-rotating reciprocating stem. The Valve Stem slides to and from the Valve Seat with a non-rotating action. This allows for perfect seating and eliminates the possibility of galling at the Valve Seat. The Valve Stem is furnished with a backseating feature to permit the repacking of the Valve Stem Packing while the Valve is in service and under pressure. These Gauge Cocks are furnished with Renewable Seats and with or without Stainless Steel Ball Checks.
