SS304 SS316L Vacuum Butterfly Valve With Manually Operated Handwheel KF25/KF40/KF50 NW25-50 Stainless Steel Butterfly Valves for Semiconductor

Used as ventilation, shut-off or high-vacuum valves, butterfly valves have a  simple structure, and can be installed in the vacuum exhaust line of a semiconductor tools. Butterfly Valves are characterised by their compact design, and high conductance. Made of stainless steel 304 or 316L, these valves are also available manually operated or electro pneumatically.

Design and Feature

• Swivel valve plate with FKM seal

• Compact size and light weight,easy installing

• Minimal face-to-face dimension,Minimal installing space

• Flow by adjusting the degree of opening and can be set to an arbitrary degree of opening.
