Edwards SP Speedivalve
Edwards SP Speedivalves are diaphragm 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.
- Easy to operate with visual indication of valve open (SP10K to SP25K)
- 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)
