Edwards SP SPEEDIVALVE MANUAL OPERATION ISOLATION VALVES – NW FLANGES

Easy to operate with visual indication of valve open (SP10K to SP25K)
Leak tight to better than 10^-6 mbar I s^-1 / 8x10^-7 Torr I s^-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)

BOC Edwards SP Speedivalves are diaphragm sealed in-line, isolation valves available in nominal bore seizes of 10, 16, 25 and 40 mm. They are all similar in construction and consist essentially of a flexible elastomer 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 body is made from aluminium and the complete valve is leak tight to better than 10^-6 mbar I s-1 /8 x 10-7 Torr I s-1 at 1 bar differential. Diaphragms are available in nitrile and fluoroelastomer. The valves terminate in NW flanges and the SP10K, SP16K and SP25K valves can be pipeline supported or panel mounted. These valves have indicators to show the ‘open’ position. The SP40K is suitable for pipeline mounting only.
