S41-466 Rotary disc shutter Bray with thread/eyelet (CS/SS/RPTFE) PN16 with handle
Rotary disc valves series 40...45
High-performance valves of the highest class with double eccentricity. Design features and a wide range of materials guarantee an almost universal possibility of using these valves. Vacuum or high pressure, low temperatures or steam, gases, abrasive media, aggressive media, fire and explosive media, an appropriate solution is offered for each case. The design of the gate allows for use both to block the flow and to regulate its flow (shut-off valves).
At the same time, the valves are able to withstand intense loads and a large number of operating cycles (1,000,000 cycles are guaranteed). The shutter ensures absolute tightness in both directions.
Compared with traditional fittings (ball valves, valves, valves), the valves of these series have significantly smaller dimensions and weight. In addition, the required torque is also significantly lower than that of traditional analogues. This significantly reduces the cost of purchasing, installing, operating and maintaining valves and actuators.
