THE NEW SERIES 44
A quantum advance in ball valve durability, cycle
life, leak tightness and automation.
Flowserve Worcester Controls Series 44 three-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 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.

Manual Valve
High Performance
An improved stem seal design, consisting of live-loaded PEEK and
Polyfill® thrust bearings 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 three-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 for stem seal adjustment;
• Inventory simplification. Mounting brackets are common to threepiece and equivalent flanged valves.

MULTIPLE END CONNECTIONS, SEAT
AND SEAL COMBINATIONS
SWING-OUT DESIGN FOR
EASY MAINTENANCE
Available through a nationwide network of distributors,
Flowserve Worcester Controls Series 44 quarter-turn ball
valves and replacement parts are stocked and ready to be
adapted to each individual application.
The Series 44 is especially well suited for use in piping systems
where line breaks are required and total entry into the line is
necessary. The center section can swing out, eliminating the
need to cut a valve out of line and having to replace both the
valve and the pipe. Because of this design, the seats, seals
and ball can all be replaced quickly and easily without disturbing pipe alignment. Acting as both a valve and a union, the
Series 44 eliminates the need for a separate union.
Features that make this tough, reliable ball valve so unique
include tight shutoff, smooth two-way flow, advanced seat
materials, a variety of interchangeable end connections, swing
away three-piece construction, and a design ready for
automation.
A variety of pipe ends, including socket weld, screw ends, butt
weld or any combination of these, enables Series 44 valves to
be adapted to fit standard and more unusual piping situations.
Series 44 (V67) valves can also be welded in place, fully
assembled with “G” graphite-coated 316 stainless steel
body seals and reinforced TFE, Polyfill, or High-per Fill®
seats.
The range of Worcester’s seat materials is unmatched and
includes Buna, Neoprene, TFE, Reinforced TFE, Polyfill,
LubetalTM, High-per Fill and UHMWPE. These seats easily handle a great majority of industrial fluids with temperatures from
-50°F to +600°F including steam, chemicals, petrochemicals,
petroleum products, caustics and fluids containing solids,
fibrous or abrasive materials.
TIGHT SHUTOFF AND
BIDIRECTIONAL SEALING
Worcester’s three-piece ball valves are designed to seal
bidirectionally against resilient seats. Unique relief slots
assist in downstream sealing and reduce torque. The ball is
forced to the downstream side under pressure and forced
against the downstream seat to effect and maintain a seal.
Consequently, the valve will give bubble-tight shutoff throughout a long service life even with seats of relatively nonresilient materials such as TFE or Polyfill. The seats are also
designed to perform a wiping action during each cycle—
cleaning foreign materials off both the seat and ball, assuring
leak-tight sealing.
The downstream sealing of Worcester’s three-piece valves
overcomes the two most common difficulties in the use of
conventional ball valves: seat damage and high operating
torque. A hole in the stem slot prevents any possibility of
damage due to trapped cavity pressure when the ball is open.
An optional ball cavity vent is available for specific applications.
The Worcester design results in smoother, more efficient
valve operation.

OPERATING TORQUE FOR
AUTOMATED VALVES
Valve Torque:
Before the actuator can be sized for any given valve application, the
operating torque required for the valve must be determined. The operating torque of the ball valve is influenced by a number of factors—
some are design- and materials-related, others are application- (service conditions) related. Design-related factors include the type and
material of the valve seats, while application factors include system
pressure, media and frequency of operation.
For complete valve operating torque data, refer to Worcester’s Actuator
Sizing Manual (ASM). This eight-page publication explains the concept
of valve torque, presents torque curves for each seat material, and
provides correction factors for media and the type of service such as
on-off operation, cycle frequency, etc.

EXTERNALS: Externals, including handles, are normally constructed of zinc plated carbon steel. Handles are vinyl coated. When required, the body bolts, nuts, retaining nut, handle nut, lockwasher, stop pin and handle are also available in stainless steel by special order (S-7 suffix in ordering code), and come standard when ordering 4466 Stainless Steel or 44AA Alloy 20 valves.
†All IPS schedules of stainless, carbon and alloy steel pipe, S.P.S. copper pipe and red brass pipe.
††To order a Series 44 valve for use with:
34 or 36 actuators, use prefix ordering code “A”. EXAMPLE: 1" A 4446 6 PMSE
39 or 75 actuators, use prefix ordering code “B”.
Caution: Ball valves can retain pressurized media in the body cavity when closed. Use care when disassembling. Always open valve to relieve pressure prior to disassembly.
