Speedivalves
Easy to operate
with visual indication of valve open (SP10K to SP25K).
Leak tight
to better than 10⁻⁶ mbar m³/h
Diaphragm isolation
Diaphragm completely isolates mechanism from vacuum system.
Robust
Extremely rugged and ‘dirty’ system tolerant
Vacuum to 9 bar
Will withstand 9 bar overpressure (SP10K to SP40K, with Co-Seal)
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.
The valve terminates in NW flanges and can be pipeline supported or panel mounted. (SP40K is pipeline supported only).
