Butterfly valve dimensions

What is the difference between a lug type butterfly valve and wafer? What are the different types of butterfly valves? Is butterfly valve the same as pressure reducing valve? Dimensions of Wafer and Lugged Butterfly Valves to Class 1rating. All dimensions are in mm unless noted otherwise.

Corrosion Resistant Shafts.

A complete butterfly valve line to provide optimal performance. Notes: General Standard valves tested to MSS SP-61. API 5testing available on request. Certified drawings available on application. AWWA Butterfly Valves (BAW) Specifications.

Butterfly valves provide bi-directional dead-end service in commercial and industrial service. To make your selection easier, NIBCO offers specification and submittal assistance. You also get the assurance of the NIBCO warranty, along with superior customer service expertise.

Types of Butterfly Valves Wafer Butterfly Valve. The wafer body is placed between pipe flanges,. Lug Style Butterfly Valve. The lug body has protruding lugs in the periphery.

Flanged Butterfly Valve. In this types, the body has flanged that match with pipe flange dimension. Butterfly Valves Ideal for precision throttling and on-off applications, especially in lighter-weight piping systems, the Flowserve family of butterfly valves is often specified for its versatility. Outstanding throttling accuracy for process control is achieved through low-friction, erosion resistant sealing surfaces with very low operating torques. Butterfly Valves Designed specifically for the waterworks industry, Lineseal butterfly valves offer the ruggedness and reliability required for buried service and performance.

Lower head loss means getting the most from your pumping station dollar. Situated in the center of pipes, butterfly valves feature a disk-shaped closing mechanism to help provide quick shutoff through an actuator visible on the outside of the valve. Choose a resilient butterfly valve with rubber seating parts for low-pressure applications.

Clow Butterfly Valves have an innovative and efficient design that offers reliable service with a bubble-tight closure. Our Butterfly Valves are available in both CL150B and CL250B, and they meet or exceed AWWA Standard C-50 latest revision. Growth of the company has been closely associated with the growth of the rubber seat butterfly valve.

The company offers a full line of butterfly valves including bonded seat, rubber seat, and buried service, available in varying sizes from to 1inches and meeting specific AWWA and ANSI standards. There are main categories of butterfly valves: Rubber-line Plastic-line and Metal. Less expensive valves for non-demanding, non-abrasive, lower temperature applications.

These valves satisfy a wide range of industrial applications and are available in carbon steel or stainless steel, as well as lug and wafer body styles. DynaCentric high-performance butterfly valves offer the high performance of ball and gate valves with the low-cost, lightweight benefits of a butterfly valve design. Flowseal high performance butterfly valves are available in sizes from - in ASME pressure classes 15 30 and 6and are available with a diverse range of actuation options.

For valves supplied with amaterial, chainwheel, the positive restraint option is recommended.
