  • 2 Flanged Ball Valve

    2 Flanged Ball Valve

    In the 2 flange ball valve structure produced by milestone valve company, the flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene inlaid into the stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is close to the ball and keep the seal. There is no PTFE bearing on the upper and lower valve stems to reduce friction and save labor. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. 2 flanged ball valve is full diameter for pipeline cleaning.
  • Composite exhaust air valve

    Composite exhaust air valve

    Find a huge selection of Composite exhaust air valve from China at Milestone. Composite exhaust air valve is a barrel shaped valve body, which mainly contains a group of stainless steel balls, rods and plugs. Composite exhaust air valve is installed at the pump water outlet or in the water supply and distribution pipeline to remove a large amount of air accumulated in the pipeline, or a small amount of air accumulated at a higher place of the pipeline is discharged into the atmosphere, so as to improve the service efficiency of the pipeline and the pump Valve quickly inhales outside air to protect the pipeline from damage caused by negative pressure.
  • Three Ways Ball Valve

    Three Ways Ball Valve

    The three ways ball valve can be divided into L-shape and T-shape. The L-shape three way ball valve is used for switching the flow direction of medium, which can connect two mutually vertical channels; the T-shape three way ball valve is used for medium diversion, confluence and flow direction switching. T-shaped thre way ball valve can connect three channels or two of them.
  • Pinless Butterfly Valve

    Pinless Butterfly Valve

    Pinless Butterfly Valve is a kind of valve which opens, closes and adjusts the fluid channel by the reciprocating rotation of the disc type opening and closing parts about 90 degrees. As a component used to realize the on-off and flow control of pipeline system, the pin-less butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, etc.
  • Stainless Steel Flange Gate Valve

    Stainless Steel Flange Gate Valve

    Stainless steel flange gate valve is an on / off control valve, used to transfer or cut off the medium. The opening and closing part of the stainless steel flange gate valve is the gate. The movement direction of the gate is perpendicular to the fluid direction. When the valve plate falls down, the valve closes to prevent the medium from flowing. When the valve plate rises, the valve opens and the medium can pass through the valve. Stainless steel flanged gate valves can only be fully opened and fully closed.
  • Manual Flanged Butterfly Valve

    Manual Flanged Butterfly Valve

    Manual flanged butterfly valve has compact structure, easy 90 ° rotary switch, reliable sealing and long service life. It is widely used for water supply and drainage in water plants, power plants, steel mills, papermaking, chemical industry, catering and other systems as regulation and cut-off.

  • Gate valve movement mode

    When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, only rely on the medium pressure to press the sealing surface of the gate plate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valve is forced seal, that is to say, when the valve is closed, the gate should be pressed to the valve seat by external force, so as to ensure the sealing surface sealing.

  • Why Should You Choose a Wafer Type Butterfly Valve for Your Industrial Applications?

    ​In the world of fluid control, the selection of the right valve is essential to ensure efficiency, safety, and long-term reliability. Among the various valve types, the Wafer Type Butterfly Valve stands out for its compact design, easy installation, and cost-effectiveness. This valve has been widely adopted in industries ranging from water treatment and power generation to petrochemicals and food processing.

  • What are the functions of the Stainless Steel Butterfly Valve?

    ​Stainless Steel Butterfly Valves are an essential part of many industrial processes. They are used in a variety of applications to regulate the flow of various kinds of fluids, including gas, steam, water, and oil among others.

  • What Are the Principles of a Ball Valve?

    A ball valve is a widely used industrial device that controls the flow of liquids or gases by using a rotating ball with a hole in the center.

  • Gate valve characteristics

    The body is made of high-grade ductile iron, which is about 20%~30% lighter than traditional gate valves, and is easy to install and maintain.

  • Application medium and working condition of butterfly valve

    Butterfly valve is mainly used for liquid, gas low pressure large diameter pipeline. It is suitable for the occasions where the pressure loss requirement is not high, the flow regulation is needed, and the opening and closing requirements are fast; Generally, the temperature is below 300 ℃ and the pressure is below 40 kg). The medium is generally used for water and gas, and the medium requirement is not high. Granular medium can also be used.
