China Thread Ends Full Bore 4 inch Brass Ball Valve Manufacturers, Suppliers, Factory

There are generally two types of double disc gate vlaves, one is the wedge double disc gate valve (that is, the sealing surface of the gate and the center line of the stem are at a certain angle, there are 2.8° and 5°, different manufacturers have different designs) , The other is the parallel double disc gate valve, the gate sealing surface of this gate valve is parallel to the center line of the valve stem, and the two gates are separated in a K shape.

The flanged butterfly valve whose stem axis deviates from the center of the disc and the center of the body at the same time, and the sealing pair is oblique cone is called Eccentric Flanged Butterfly Valve. The Eccentric Flanged Butterfly Valve produced by Milestone Valve Company has a double eccentric flange butterfly valve and a triple eccentric flange butterfly valve. Compared with ordinary butterfly valves, the Eccentric Flanged Butterfly Valve has an eccentric structure design. The sealing surface is instantly separated when the valve is opened and closed, reducing friction. Extend the service life. It can be used in petroleum, chemical, water supply and drainage, metallurgy, pharmaceutical and other industries, and can be applied to a variety of corrosive and non-corrosive gases, liquids, and fluid-filled pipelines.

Milestone is China manufacturer & supplier who mainly produces Resilient wedge Iron gate Valves with many years of experience. Resilient wedge Iron gate Valves is a kind of gate valve, and its sealing surface is at a certain angle with the vertical centerline, that is, the two sealing surfaces are wedge-shaped. Resilient wedge Iron gate Valves are divided into bright stem gate valve and dark stem gate valve, wedge single gate valve and wedge double gate valve. The driving methods are: electric, pneumatic, manual, pneumatic and hydraulic, etc. The connection methods are flanged, welded, and clamped.

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.

Forged Steel Gate Valves is a processing method that uses forging machinery to apply pressure to metal valve blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forged Steel Gate Valves can eliminate the as-cast looseness of the metal and welded holes through forging. The mechanical properties of the forged parts are generally better than those of the same material. Forged Steel Gate Valves produced by Milestone Valve Company have excellent performance and are widely used.
