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).
