  • PTFE lined flanged ball valve

    PTFE lined flanged ball valve

    PTFE lined ball valve is used to control non corrosive, general corrosive and strong corrosive media. The inner surface of the valve body is unlined or covered with various kinds of optional rubber. It is suitable for various working temperatures and fluid pipelines. The ball valve uses a ball with a round through hole as the opening and closing part. The ball rotates with the stem around the center line of the valve body to realize the opening and closing of the valve.

  • Forged steel 3-PCS peumatic ball valve

    Forged steel 3-PCS peumatic ball valve

    1. Resistance to sulfide stress cracking: the contact medium materials of forged steel ball valve are selected according to the standard of nace01-75 of American Society of corrosion engineers, and nickel plating is carried out according to the standard, which can meet the requirements of sulfide environment.

    2. Forged steel ball valve uses polymer or metal as sealing material, which has excellent sealing performance at high temperature and high pressure.

    3. It can prevent the valve rod from rising out of the packing box due to the inverted structure of the packing box.

    4. Forged steel ball valve is widely used in chemical, oil refining, oil and gas, natural gas, steel and other media pipeline. The advantages of forged steel ball valve: the resistance of flow is small, and the actual value is 0. Secondly, the sealing performance of forged steel ball valve is reliable. The seats of most forged steel ball valves are made of polytetrafluoroethylene elastomer, which can realize complete sealing in a large range of pressure and temperature, and the working medium is sealed reliably on the double spherical surface. Good corrosion resistance and long service life.

  • API6D 3-pcs fixed ball valve

    API6D 3-pcs fixed ball valve

    1. Double block and discharge function: the fixed ball valve adopts spring preloading floating valve seat. No matter the valve is in full open and full close state, the upstream and downstream valve seats block the fluid, and the retention in the valve body cavity is discharged through the discharge valve.
    2. Automatic pressure relief function: when the abnormal pressure rise caused by the temperature rise of the medium in the valve body cavity, it is not necessary to pass through the safety valve, but only rely on the valve seat function to automatically relieve the pressure, which is very important to ensure the safety of the valve when conveying liquid medium.
    3. Fire safety structure: all valves have fire safety function, and their design and manufacture comply with API607 and APIfa specifications.

  • Floating ball valve

    Floating ball valve

    1. In all kinds of valves, the flow resistance of ball valve is the smallest. When the full diameter ball valve is opened, the ball channel, valve channel and connecting pipe diameter are equal and form a diameter, and the medium can flow through almost without loss;
    2. The ball valve can be fully closed and fully opened by rotating 90 ° and the valve can be opened and closed quickly. Compared with gate valve and stop valve of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.

  • Italian short type wafer thin flange ball valve

    Italian short type wafer thin flange ball valve

    Thin wafer ball valve is one of the ball valves. It is a new generation of ultra short flange distance ball valve developed by introducing Italian technology for domestic design. The shape of ball core channel is rectangular, V-shaped and O-shaped. The product has the characteristics of compact structure, small volume, light weight and convenient installation. It can be widely used in the fields of petroleum, chemical industry, metallurgy, power station, light industry and so on. It can automatically adjust or cut off the oil, water, gas, pulp or fibrous fluid.
