    1. Soft seal gate valve is suitable for non corrosive gas and liquid medium at normal temperature (≤ 80 ℃). Such as water, air, oil, water treatment sewage and other pipelines. And has a very good sealing effect, almost can achieve zero leakage.
    2. Metal seal gate valve is suitable for high temperature (≤ 425 ℃) with slightly corrosive gas and liquid. Such as steam, heat transfer oil, sewage, petroleum, chemical industry, metallurgy, pipeline. Can have a certain degree of wear resistance.
    3. The difference between the soft seal gate valve and the metal seal gate valve is that the sealing performance of the soft seal gate valve is better than that of the metal seal gate valve

  • DIN3352 F4/ F5 non-rising stem resilient soft seat gate valve

    DIN3352 F4/ F5 non-rising stem resilient soft seat gate valve

    When the Non rising stem valve is opened and closed, the steering wheel and the valve stem are connected together and relatively motionless. It is driven to lift the valve disc upward and close the valve by rotating the valve stem at the fixed point. Rising stem valves lift or lower the disc through the screw drive between the stem and the steering wheel. The simple point is that rising stem valve is the valve disc connected with the stem to do up and down movement, the steering wheel is always at the fixed point.

  • JIS cryogenic gate valve

    JIS cryogenic gate valve

    When the low temperature gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed to the valve seat on the other side to ensure the sealing of the sealing surface, which is self sealing. Most gate valves are forced to seal, that is to rely on external force to force the gate to the valve seat to ensure the sealing of the sealing surface

  • Wedge gate valve

    Wedge gate valve

    Wedge gate valve because of its valve sealing surface and vertical center line into a certain angle, good sealing, so it can withstand large pressure. In general, the valve stem of wedge gate valve has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment; the seal between gate and valve seat is made of cemented carbide, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant and has long service life; the valve body has complete materials, and the packing and gasket are based on the actual working conditions or user requirements.

  • GOST cast steel/ stainless steel gate valve

  • JIS cast steel/ stainless steel gate valve

    JIS cast steel/ stainless steel gate valve

    1. The fluid resistance  is small, and its resistance coefficient is equal to that of pipe section of the same length.
    2. Simple structure, small volume and light weight.
    3. Tight and reliable.
    4. Easy to operate and can be opened and closed quickly. From full opening to full closing, it only needs to rotate 90 ° to facilitate remote control.
    5. The maintenance is convenient, the structure is simple, the sealing ring is generally movable, and it is convenient to dismantle and replace.
    6. When the valve is fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
    7. The valve has a wide range of applications, ranging from small to several millimeters in diameter, and from high vacuum to high pressure.

  • JIS cast iron gate valve

    JIS cast iron gate valve

    1. The flow resistance is small, and the internal structure of the valve body is straight through, so the medium can be unobstructed;
    2. The movement direction of the gate valve of cast iron rising stem gate valve is perpendicular to the flow direction of medium, and the opening and closing speed is fast and labor-saving;
    3. The channels on both sides of the gate valve are symmetrical to each other, and the medium can flow freely to both sides, so it is easy to install the cast iron rising stem gate valve;
    4. It has the advantages of simple structure, short structure length, good manufacturing industry, and can be used in various fields;
    5. Made of ductile iron, the valve body is very light, only about 20% ~ 30% of the traditional gate valve;
    6. Compact structure, good rigidity of valve, smooth channel, unique material of sealing surface, reliable sealing performance and long service life.

  • Pneumatic knife-shaped gate valve

    Pneumatic knife-shaped gate valve

    The pneumatic knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and other advantages. It can work normally under the working pressure of 1.0mpa-2.5mpa and the service temperature of – 29-650 ℃. The knife gate valve has shear function, which can scrape off the adhesion on the sealing surface and automatically remove the impurities. The stainless steel gate valve can prevent the seal leakage caused by corrosion.
