    Feature:

    1. Double eccentric structure design. The uniquely designed lip sealing structure achieves zero leakage of two-way bubble level under elastic interference and self-sealing.
    2. Interchangeable PTFE seats can be used in a variety of different working conditions to achieve long service life and effect.
    3. Anti-blowout valve design.
    4. Under the working condition of fugitive medium, the low-leakage carbon fiber bowl type combined with packing structure can be adopted to meet the requirements of ISO15848 and API622 standards.
    5. The tangential pin of the valve stem is half on the valve plate and half in the valve stem, and the tangential positioning makes the squeeze force of the valve plate and the valve instead of the shear stress, making the connection more reliable.
    6. Equipped with ISO 5211 standard connecting plate, pneumatic device, electric device, gas-liquid linkage device and other remote control mechanisms can be installed for automatic control system.

    Features:

    1. The structure length is short, which brings great convenience to the valve installation, handling, storage and pipeline layout, and can save costs.
    2. Reduce line vibration, in order to reduce line vibration to a minimum or eliminate line vibration, the check valve must be closed as soon as possible before the liquid flow has a chance to reverse flow. The size of each flap in a double-lobe check valve Only half the size of a fully constructed check disc, it experiences reduced fluid resistance and faster movement to the closed position. They have a radius of rotation half that of conventional check valves.
      Its leading distance from the open to the closed position is halved, thus reducing travel time by up to 50%
    3. The double-piece check valve reduces water hammer, and the flaps of the double-piece check valve have been greatly reduced in weight, which can reduce the slamming and water hammer phenomena to a small limit Degree.

    Features :

    1. Bellows sealed globe valve is simple in structure and good in performance.
    2. The stem nut adopts surface nitriding to improve the surface hardness .
    3. The medium flange bolt is made of high-strength alloy steel, with the ability to resist high temperatures.
    4. Double sealing of packing and bellows to achieve zero leakage.
    5. The bellows is designed in the inner cavity of the valve cover, which avoids direct flushing with the medium and improves the service life of the bellows.
    6. The bellows adopts 2~4 times overlap to prevent the valve leakage due to the damage of the single layer of the bellows, and prolong the service life of the valve.
