How do I know what size butterfly valve I have?
How to Determine Butterfly Valve Dimensions
- Length A – Length of butterfly valve body + stem endpoint.
- Length B – Length from centerline x-axis to valve end.
- Length C – thickness of the valve body.
- Length F – length of the key.
- Length H – diameter of stem.
- Length J – Hole size.
- K – thread size.
- L – number of holes.
What is AWWA c504 standard?
Full Description. This standard covers rubber-seated butterfly valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with various body and end types, for fresh and reclaimed water having a pH range from 6 to 12 and a temperature range from 33° to 125°F (0.6° to 52°C).
What makes a butterfly valve high performance?
What is a High Performance or Double Offset Butterfly Valve? High Performance Butterfly Valves use a disc offset from the seat center, hence the name Double Offset. This feature allows the use of offset butterfly valves in high‐pressure applications such as ethanol or HVAC.
What is an AWWA valve?
Butterfly valves are used to prevent and isolate the flow of fluid in industrial sectors. They are easy to handle and very fast in stopping the flow. Awwa butterfly valve doesn’t leak from anywhere and won’t damage by corrosion.
How thick is a 4 inch butterfly valve?
What is the width of the butterfly valve? The overall width is 9.1″. However, I think you’re referring to the thickness, which is 1.6″.
What is an AWWA butterfly valve?
DeZURIK AWWA Butterfly Valves meet the requirements of AWWA C504 and C516 standards. They are used for shutoff on clean water and gases. Offset disc design, corrosion resistant shaft, stainless steel disc edge, and self-compensating shaft seals are features on all DeZURIK AWWA valves.
What is double offset butterfly valve?
Double offset butterfly valve is popularly known as a high-performance butterfly valve and has two offsets from the valve body’s center: The shaft axis is offset from the disc’s seat and body seal’s centerline, and. The shaft axis is eccentric to the pipeline’s/valve’s center line.
What is triple offset valve?
A Triple Offset Butterfly Valve has 3 separate offsets. Two of the offsets apply to the location of the shaft in respect to the centerline of the bore and the centerline of the disc/seat sealing surfaces. Triple Offset: The third offset is the geometry design of the sealing components.
What is KV value for valves?
The Kv value is the volume flow of a medium per time unit with a pressure drop of 1 bar at a specific temperature. In practical terms this means that it is only possible to make a statement on the flow rate at a specific opening degree of the valve.
