TRIPLE OFFSET BUTTERFLY VALVE STANDARD FEATURES

INTRODUCTION:Pratt Industrial Triple Offset Butterfly Valve is from the family of quarter-turn valves. This valve is designed and manufactured to meet API 609 and ASME B16.34 specifications. The Pratt Industrial Triple Offset Butterfly valve offers a metal-to metal seating design that can provide the user with an alternate design to the traditional gate valve while offering the user: n Lower weight solution w/zero leakage shut off to API 589 n

Less weight

n Easy to automate

n Can be used to modulate the process for level, flow, temperature and pressure

DESCRIPTION OF VALVE:n Sizes: from 3” (80mm) to 48” (1200mm)

as standard with additional sizes considered upon request.

n Pressure Class: 150#, 300# & 600# Class ASME rated valves are standard with higher-pressure class valves considered upon request.

n Temperature Range: -46 deg. C to 400 deg. C

n Seats; Body Seat is 316SS w/graphite; disc seat316SS as standard; other designs availableupon request

n Face to Face: standard F/F dimensions are per AMSE B16.10, API 609, ISO 5752 and BS 5155.

n Flow Direction: all valves offer bidirectional flow capability while complying with API 598 for seat leak testing.n Fire Safe: TOBV are inherently fire safe

by design

n Top Works: all TOBV’s bonnets are designedto ISO 5211 bolt pattern and can be ordered bare stem, Gear Actuators can be supplied by request.

APPLICATIONS:n Block/Isolation

n Modulating; manual, pneumatic, motor operator or hydraulic.

INDUSTRIES:n Refinery

n Chemical

n Petrochemical

n Power

n Steam Generationn Water/Waste Water Treatment

BUTTERFLY VALVE FEATURES:n Anti-blow out proof stemn Field replaceable Seats for the disc seat and the body seatn Large bearing surfaces in bonnet n Graphite packing as standard with

alternative packing materials and configurations available upon request including live loaded packing, Fugitive Emissions qualified and lubricator designs are available

n Shaft Key and tangential disc pin provide for

positive disc to shaft connection

DESIGN:The Triple Offset Butterfly valve has been designed to answer the industries demand for an alternate solution to gate valves and ball valves where weight, space, performance, and the ability to modulate to the process flow were

an issue. In regard to the “performance” aspect, Pratt Industrial Triple Offset Valve design provides for:

n Friction free seat design: this isaccomplished by the design of the triple offset engineered solution. In the butterfly class of valves there are three basic families

or designs; Concentric, Double Offset,

otherwise known as High Performance and

now the Triple Offset design. The drawback

of the previous design is contact between the

seat and the Disc surfaces which causes:

1) Premature wear of the seat in general areas. 2)Increased breakout, seating and run torqueswhich increase actuator costs and degrade valve

performance in modulating applications.

n Bidirectional flow provides leakage performance

according to API 598 and exhibits the following

advantages:1)The “torque seated-design” facilitates closingthe valve using the fluid force. The sealing capacity of the sealing surface is directly

proportional to the torque applied.

2) The “concave” design of the disc on the

opposing side of the shaft acts like a flow wing

creating a “low pressure zone” which artificially

increases the fluid dynamics of the valve, which

enhances the valves flow capacity.

n Testing: all seat leak testing is in accordancewith API 598. Other testing standards such as

ISO 5208 are available upon request.

TRIPLE ECCENTRIC DISC-SHAFT

THE TRIPLE OFFSET BUTTERFLY VALVE

DESIGN: 1st Offset: It is accomplished by moving the centerline of the shaft away from the seating plane.

2nd Offset: It is accomplished by moving the

centerline of the shaft offset from the centerline bore

of the valve.

These two design features cause the disc to open and

close relative to the body seat in a “camming” action

and effectuate the position seated valve design which is

typical of the High Performance Butterfly Valve,

however there is still contact between the disc and the

seat in the first several degrees of opening and closing

which can cause premature wear of the seat in the

general areas.

In order to achieve an API 598 Shut Off classification

a 3rd offset needed to be introduced to make the valve

a “torque seated” design with graphite and metal

seating surfaces.

3rd Offset is accomplished by adjusting the cone angle

created by the 1st and 2nd offset angles at some point

downstream of the valve in the center of the piping to

the adjacent piping wall as depicted in the illustration

below “Sticking tendency”.

By incorporating the 3 offsets into one design typical

of gate valves is eliminated with seat contact

throughout the entire stroke reducing run torques and

improving actuator modulating performance at the

same time.

n GWC Triple Offset Butterfly Valve has a unique seat and seat retainer design to minimize

the seat movement.

n The seat retainer is bolted to the body holding the seat in the seat pocket, thus avoiding

a blow-out.

n The Valve design is suitable for dead-end service with shaft downstream and in the lug

or double flange configuration.
