Two-way Sealing Hard-on-hard Rotary Ball Valve
Product overview
Bidirectional flow hard-to-hard rotary ball valve is a combination of the superior sealing performance of the ball valve and the advantage of the butterfly valve structure research and development, it has a fixed ball valve superior bidirectional pressure, can contain the use of fine particles of liquid pipeline, with the use of high temperature, long life and other practical advantages. Its essence is a combination of butterfly valve and eccentric half ball valve structure function, superior to the installation of half ball valves and fixed ball valves. The sealing principle combines the front sealing of the fixed ball valve with the forced sealing of the eccentric butterfly valve to realize the high and low bidirectional cutting in the pipeline. Stop at pumpIn operation, when the outlet water pressure of pipeline is higher than the inlet water pressure, the use of rotary ball valve can effectively prevent backwater flow, which is also a function of butterfly valve and half-ball valve.It can be use for advanced technology of martensitic stainless steel, austenitic stainless steel, hard alloy and that like by supersonic plasma spray and vacuum protection. The valve will be transformed by its superior value, and it will change the valves of the network, and it will make the general network especially the water system and the water system to enjoy the power of the electricity and gas and the high quality products of the high-end system, and the high quality products.
