Edwards Speedivalve SP10K

Edwards Speedivalve Model SP10K

Pre-Owned but unused (New Old Stock)

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.  

Features and Benefits
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)
