  Soft seal gate valve

  [product overview] Gate valve is one of the most widely used valves in various fluid transmission projects. Traditional gate valves are prone to fluid leakage and serious corrosion of internals. At present, the common soft seal gate valve on the market is easy to leak at the shaft seal of the valve stem, so it is impossible to replace the seal ring without water and at any opening. The elastic seated gate valve adopts novel structural design, strict manufacturing technology and high-performance new materials, which overcomes the defects of the traditional gate valve, such as poor sealing, easy corrosion of internals, especially the gate valve, rubber elasticity fatigue and easy aging. It has reliable sealing performance, light operation, simple and convenient maintenance and long service life. It is applicable to domestic water system, water supply and drainage system, sewage treatment system, chemical fluid transmission system, etc. it is used as a cutting device on the fluid pipe line in construction, urban environmental protection, petrochemical, pharmaceutical, food, metallurgy, textile, electric power and other industries (not applicable to throttling).

  Knife gate valve

  The knife gate valve produced by Zhejiang Huachi Valve Co., Ltd. is widely used in coal, filter residue slurry, wastewater, slurry, dirt, pulp, ash slurry, etc. Knife gate valve is also called knife gate valve, knife type slurry valve. Its opening and closing part is a ram. The movement direction of the ram is perpendicular to the fluid direction. The medium is cut off by a knife edge ram that can cut fiber materials. The ram has two sealing surfaces. The two sealing surfaces of the most commonly used model ram valve form a wedge. The wedge angle varies with the valve parameters, usually 50. The ram of the wedge-shaped knife gate valve can be made into a whole, which is called a rigid ram; It can also be made into a ram that can produce slight deformation to improve its processability and make up for the deviation of the angle of the sealing surface in the processing process. This kind of ram is called an elastic ram. In fact, there is no chamber in the valve body, and the ram rises and falls in the side guide groove, and is tightly pressed on the valve seat by the lug at the bottom. If you need to achieve high medium tightness, you can choose O-shaped sealing valve seat to realize two-way sealing. Knife gate valve has small installation space, low working pressure, not easy to accumulate debris, and low price

  Stainless steel gate valve

  Stainless steel gate valve: the valve body, bonnet, gate and gate rod are made of stainless steel. The sealing surface of the valve seat is polytetrafluoroethylene, stainless steel + cemented carbide or surfacing cemented carbide. The filler is generally made of cemented carbide, polytetrafluoroethylene, asbestos graphite or flexible graphite. The nominal size is dn15~dn800, the working pressure is 1.6mpa~20.0mpa, and the applicable temperature is ≤ 200 ℃. It is suitable for nitric acid and weak corrosive medium pipelines.
