3 Piece ball valves designed to meet all requirements of ANSI B16.34
A quantum advance in ball valve durability. cycle life, leak tightness and automation.
Worcester's Series 44 3-piece ball valves, for many years the most respected ball valve design in the industry, are now better than ever. A major research, design and testing program brings you a new valve, designed to ANSI B16.34 specifications with advanced seal technology and body mount bracket design. This means a very strong, tough valve that can handle the pressure and unforseen piping strains with a stem seal that extends operational cycle life and a standardized overall design that keeps parts inventory to a minimum. Then there's documentation. B16.34 means complete traceability of assembly and testing procedures, heat codes and foundry identification. Full CMTRS (Certified Material Test Reports) on pressure vessel parts are optionally available. Valve identification is provided on a stainless steel nameplate meeting MSS SP-25.
High Performance
A new stem seal design, consisting of PEEK and Polyfill(D thrustbearings and seals, significantly increases valve cycle life over conventional ball valves and extends time between adjustments. In manual valves, the two spring washers are compressed by two retaining nuts. A single Nylon-insert locking nut and four spring washers are used on automated valves.
Body Mounted Actuator Design
Actuators for Worcester's Series 44 3-piece valves are mounted on rigid, precisely machined, box style brackets bolted to the valve center section. This brings a number of advantages to the valve user: Actuator loads are on the valve body. Actuators and brackets can be removed for service without affecting valve or piping integrity. Easy access to stem seal adjustment. inventory simplification. A few mounting brackets are common to 3-piece and equivalent flanged valves.
