  • Product Description
  • German standard F4 soft seal gate valve introduction

    German standard F4 dark rod soft seal elastic gate valve is suitable for liquid and gas medium pipelines and equipment, as the role of cutting and adjusting medium.

    The elastic soft seal gate valve uses the motion direction of the elastic gate to be perpendicular to the direction of the fluid, so the soft seal gate can only be fully opened and fully closed, and can not be used as regulation and throttling. The soft seal gate valve uses the overall coating of the gate plate to produce deformation compensation to achieve good sealing effect, and overcomes the general poor seal, water leakage and rust phenomenon of the gate valve. The gate valve has the characteristics of quick installation, easy maintenance, long service life and not easy to produce water hammer.

    The bottom of the flexible seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris deposition, so that the fluid is unimpeded.

    The hand wheel is closed clockwise and open anticlockwise. No leverage is allowed.

    Two German standard F4 soft seal gate valve performance characteristics

    1. It is not easy to break. In the past, the traditional cast iron soft seal gate valve is often broken due to external object hit, collision or overlap. As the soft seal gate valve to use ductile iron, this situation has been greatly reduced.

    2, corrosion resistance, soft seal gate valve body using powder epoxy resin coating, can prevent corrosion and rust valve body, and can be used for sewage system.

    3, the whole package of rubber, soft seal gate valve plate using high-quality rubber for the whole inside, outsourcing rubber, domestic first-class rubber vulcanization technology makes the vulcanized valve plate can ensure the precise geometric size, and rubber and ductile iron gate connection firm, not easy to fall off and elastic memory is good.

    4. Flat-bottom valve seat, traditional gate valve is often deposited in the bottom groove of the valve after water washing tube because of external objects such as stones, wood blocks, cement, paper scraps, debris and so on. Easy to cause can not close close and form water leakage phenomenon, soft seal gate valve with the same flat bottom design and water pipe, not easy to cause debris deposition, so that fluid unobstructed.

    5, three "O" type sealing ring, because the stem uses three "O" type sealing ring design. It can reduce the friction resistance of the switch, greatly reduce the leakage phenomenon and can replace the sealing ring without stopping the water construction.

    6, help to drink, because the valve body is coated with non-toxic epoxy resin inside, the internal and external surfaces of the gate valve are completely covered with rubber without rust water or corrosion phenomenon, available for drinking.

    7, casting valve body, the valve body adopts precision casting, precise geometric size makes the valve body without any finishing inside to ensure the tightness of the valve.

    8, light weight, the body is made of ductile ink casting, weight than the traditional gate valve weight reduction of about 20 percent to 30 percent, convenient maintenance.

    Three soft seal gate valve use characteristics

    1. Small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

    2, less effort when opening and closing. Is compared with the globe valve, because whether it is open or closed, the direction of the ram movement is perpendicular to the direction of the medium flow.

    3, high height, long opening and closing time. The opening and closing stroke of ram is large, and the fall is carried out by screw.

    4, water hammer phenomenon is not easy to produce. The reason is the long shutdown time.

    5, the medium can flow to either side of any direction, easy to install. The gate valve channel is symmetrical on both sides.

    6, the structure length (the distance between the two connecting end faces of the shell) is small.

    7, the shape is simple, the structure is short, the manufacturing process is good, the application range is wide.
