Butterfly Valve

A Butterfly Valve is a device that uses a quarter-turn of a disc to regulate material flow over wide pipes.
An actuator that controls the disc’s motion is fastened to a rod that passes through the disc’s center. The disc is either perpendicular or parallel to the medium flow. Any position of a butterfly valve results in a change in pressure because the disc is always in the flow.
Sound systems need countable valves to function properly. Butterfly control valves from our selection are created with accurate, to industry standards-made disc valves that are exactly sized for a variety of applications.

A butterfly valve initiates, slowly advances, or terminates media to control flow. The disk can be used to open and close any program that is compatible with low-torque rotations. Because they are heavier and less expensive than other types of valves, butterfly valves are typically preferred.
In particular procedures, high temperatures and corrosion can easily degrade a valve’s seal. The butterfly valve can withstand temperature fluctuations. Given that one leak could harm the environment or public safety, high-risk industries like energy production and petroleum processing require seals to maintain their integrity.

Butterfly Valve Specifications

All Sure Flow Butterfly Valves meet API-609, MSS SP-67, and ISO 5752 face-to-face dimensions. Butterfly Valve sizes from 2″ to 12″ are rated at 250 psi WOG service and valve sizes from 14″ and larger are rated at 200 psi WOG service. All Butterfly Valves are full rated on dead-end service.  All Butterfly Valve bodies are ductile iron 65-45-12. They are bi-directionally tested in both directions and are bubble tight with zero leakage. Lug style bodies are full rated and suitable for ASME Class 125 and ASME Class 150 flanges. Wafer style bodies are suitable for ASME Class 125, ASME Class 150, JIS, DIN or B.S. flanges. Secondary seals are self-adjusting. All elastomers and all internal bearings are non-corrosive and non-metallic. EPDM seats are suitable for 250°F sustained high temperature and capable of 2000 ppm on chlorinated applications.
