a 1, vacuum Industrial Valves structure characteristics and purposes. Vacuum Industrial Valves body for casting forging structure, using the parallel double sealing and half a mandatory two-way sealing. Seal movement in place, the wedge to gradually move, to achieve zero leakage. 2. Vacuum sealing face of the globe valve has a small friction, opening and closing, light, the sealing surface wear self-compensation, etc. 3. Vacuum valve has simple structure, compact structure, convenient maintenance, long service life, etc. 4. Vacuum valve cover packing chamber with vacuum sealed structure, with the expansion and compression function, adopt high strength expansion material, make the system completely isolated from the atmosphere, has a good system of air tightness. The letter 'S'. 5. Vacuum Industrial Valves flange connections and welding connection, the connection points for manual and electric drive way. The valves are suitable for working temperature ( < 425 c) And ( < 550C） Pipes and working medium ( Water, steam, or air) As the opening and closing device, especially suitable for power plant steam turbine condensate and vacuum negative pressure system, have the effect of vacuum isolation seal.

In an age when ductile iron gate valve is increasingly important, the researchers believe manufacturers should pay close attention to their results.
We would appreciate your immediate attention to gate valve.
To derive the optimal value out of resilient seal gate valve resilient seated gate valve for your home, make sure they're purchased from a globally certified organization to ensure quality in use. Such an offer can be found at Mech Valve.
os & y valve fire protection has become a serious problem for an increasing number of people around the world, that's why highly effective are developed by Shenzhen Mech Valve Trading Co., Ltd..
