  • Quick Exhaust Valve

    Quick Exhaust Valve

    Quick exhaust valve is based on the buoyancy characteristics of water on stainless steel floating ball When the water level in valve rises, the floating ball will automatically float up under the buoyancy of water until it is connected with the sealing surface of the exhaust port. When the water level in valve decreases, the ball will drop with the water level. At this time, a large amount of air will be injected into the pipe through the exhaust port. After being installed on the pipe, the ball will automatically open / close the exhaust valve by using the inertia of water to the floating ball Air port.
  • Butterfly Control Valve

    Butterfly Control Valve

    Butterfly control valve is a simple regulating valve that can be used for switching control of low-pressure pipeline media; it can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline.
  • 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.
