This Edwards SP40K Speedivalve is KF40 with an Fluoroelastomer diaphragm. It is used as an in-line, isolation valve in vacuum systems. 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.

This Edwards Speedivalve terminates in NW40 flange and is pipeline supported only.

• 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 (SP10K to SP40K, with Co-Seal)
