Speedivalve ISO-KF
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
