    Features

    Trunnion ball valves are mainly used in the industries of natural gas, oil products, chemicals, metallurgy, urban construction, environmental protection, foodstuff etc. Among them, the sulfur-resisting series products are applicable for seriously corrosive natural gas pipeline containing hydrogen sulphide mediums and impurities.

    1. Distinctive Seating Structure

    According to the extent of pressure, medium properties and sealing requirements, Trunnion ball valves may be made to front seal structure, back seal structure, or front-back dual seal structure.

    2. Self-relieving Structure

    In case of abnormal rise of pressure at middle cavity, ball valve of single seal structure is provided with self-relieving function, while ball valve of dual seal structure uses the auxiliary pressure relief device on valve body to carry out pressure relief.

    3. First Aid of Seal

    The valve is designed with an auxiliary seating emergency seal system, as shown in the figure. In case of soft seal damaged, or failure of seal in an emergency circumstances, emergency seal may be effected by injecting in sealant through auxiliary sealing system. If needed, emergency seal assembly can be used to rinse and lubricate the seating area.
    Plus, valve stem can also be designed with an auxiliary emergency sealing system.

    4. Fire Protection Strcture

    If requested by working conditions and users, ball valve may be designed to fireproof. The fireproofing design of ball valve is to the standards of API607 and JB/T6899. In case of soft seal ring burnt in fire, the fire protection structure of ball valve functions to prevent mediums from mass leakage, thus to avoid fire spreading.

    5. Antistatic Structure

    When operating the valve, the friction between the ball and seat will produce electrostatic charge that can be accumulated on the ball. To prevent static spark, an antistatic device is placed on the valve to derive the electric charge accumulated on the ball.

    6. Locking Device

    To prevent misoperation and the unexpected open or close caused by the unpredicted circuit vibration, a locking device is designed at the fully opened and closed positions of hand operated ball valve. This design is proven especially good and effective in the production line of inflammable mediums of petroleum and chemicals, or when valves are mounted outdoors.
