Soft-sealed gate valves are widely used in water supply, sewage, construction, petroleum, chemical, food, medicine, textile, power, shipbuilding, metallurgy, energy systems and other fluid pipelines as regulating and blocking devices.
● Flat-bottomed valve seat, without the accumulation of dirt, ensuring more reliable sealing for the elastic seat soft-seal gate valve;
● The valve disc is entirely made of nitrile rubber;
● The valve inner parts are made of corrosion-resistant non-rust steel and copper alloy material, which can be used for sewage system to adapt to the harsh working environment;
● Small in size and light in weight, making it easy to install and maintain;
● The valve stem is equipped with three O-ring seals, which significantly reduces the frictional resistance during the opening and closing process. The operation is smooth and there is no leakage.
● The design standard adopts GB/T 12234
● The structural length standard adopts GB/T 12221
● The test and inspection standards adopted are GB/T 13927 and JB/T 9092
● The standard for the connection flange is: GB/T 9113, JB/T 79, HG20592
