  • DESCRIPTION

    Features of pneumatic soft seal gate valve:

     1. The valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body. It can be used in sewage systems and is not easy to break. In the past, traditional cast iron gate valves often broke due to being hit, collided or overlapped by foreign objects.

    2. The three "O" ring sealing ring design can reduce the friction resistance during switching, greatly reduce water leakage, and replace the sealing ring without stopping water.

    3. Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate valve are completely covered with rubber without rust or corrosion, and can be used for raw drinking.

    4. The valve body is precision cast, and the precise geometric size ensures the sealing of the valve without any finishing work on the northern part of the valve body.

    5. The body is made of ductile graphite casting, which is about 20% to 30% lighter than traditional gate valves, making it easy to maintain.

    Performance advantages of pneumatic soft seal gate valve:

     The pneumatic soft seal gate valve has the advantage of corrosion resistance. The valve body is coated with powder epoxy resin, which overcomes the corrosion and rust of the ordinary gate valve body and can be used in sewage systems.

    The bottom of the pneumatic elastic seated gate valve body (equivalent to the bottom of the pipeline) has no gate groove and is in a flat state, which will not cause trapped debris. It solves the problem of traditional gate valve debris such as sedimentation in the groove of the valve bottom, which can easily cause failure. Closes tightly to prevent leakage, allowing fluid to flow unimpeded.
