PRODUCT DATA SHEET 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). FEATURES AND BENEFITS • Easy to operate with visual indication of valve open (SP10K to SP25K). • Leak tight to better than 1 x 10⁻⁶ mbar ls⁻¹ (1 x 10⁻⁷ Torr ls⁻¹). • Diaphragm completely isolates mechanism from vacuum system. • Extremely rugged and ‘dirty’ system tolerant. • Will withstand 9 bar overpressure
