Edwards SP25K Speedivalve (KF25) Diaphragm Isolation Valve

Edwards SP25K Speedivalve has a viton fluoroelastomer diaphragm and are sealed in-line, isolation valves. The construction consists essentially of a flexible elastomeric diaphragm which is sealed onto a lightly polished seat by a screw thread mechanism. The mechanism is isolated from the system by the diaphragm resulting in an extremely rugged and ‘dirty’ system tolerant valve. The valve terminates in a KF25 (NW25) flange and can be pipeline supported or panel mounted.

Features and Benefits:

• The manual isolation valve with KF25 flange is easy to operate with visual indication of valve open
• Leak tight to better than 10-6 mbar ls-1 / 8 x 10-7 Torr ls-1
• Diaphragm completely isolates mechanism from vacuum system
• Extremely rugged and ‘dirty’ system tolerant
• Will withstand 9 bar overpressure (with Co-Seal)
