Butterfly valves
Wafer , Lug and Flanged - Hi-PERFORMANCE - TRIPLE ECCENTRIC
Butterfly valves are quarter turn having disc attached to a shaft with bearings facilitating rotation.
These are considered high-recovery valves since only the disc obstructs the valve flow path. The flow capacity is relatively high and the pressure drop across the valve is relatively low. These extended stem butterfly valves are used for limited throttling where a tight shut-off is not required.
As one of the most popular types of valves, butterfly valves are commonly used in various industries due to their ease of operation and cost-effectiveness. Also known as high performance butterfly valves, these work by using a disk to regulate the flow of fluids in a pipeline, which can be rotated to control the rate of flow. Butterfly valves manufacturers in India offer a variety of materials, sizes, and designs to suit different applications and requirements, making them a versatile and widely used valve type.
These high performance Butterfly valves are the most economical for more prominent lines i.e. chemical services, water treatment etc. available sizes are 2" to 48" & go up to 96". Butterfly valves generally have small face-to-face dimensions, so they weigh less than most other valves. Moreover, these comply with ASME face-to-face dimensions and pressure ratings enabling the valve to be easily retrofitted in line regardless of the manufacturer.
The UL approved butterfly valves with applicable standards for design include AWWA C204, API 609, MSS SP-69 and API 598 for testing requirements.
