China 4 inch Brass Gas Ball Valve With Certification Manufacturers, Suppliers, Factory

Screw ball valve is suitable for PN1.0 ~ 4.0MPa, the working temperature of -29 ~ 180℃ or -29 ~ 300℃ of various pipelines, used to cut off or connect with the medium in the pipeline.Screw ball valve is suitable for PN1.0 ~ 4.0MPa, the working temperature of -29 ~ 180℃ or -29 ~ 300℃ of various pipelines, used to cut off or connect with the medium in the pipeline.

The butterfly plate of the lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0-90 degrees, which can play the role of flow regulation. When the butterfly plate rotates to 90 degrees, the valve reaches the maximum opening, easy to operate.

Milestone Valve Co. Ltd. is a professional manufacturing enterprise specializing in the design, development, production, sales and service of pump valves. At present, the products have covered more than 20 provinces and cities across the country, and are exported to Southeast Asia, the Middle East, and Europe and the United States. The valve products produced are widely used in water supply and drainage, electric power, petrochemical, metallurgical and other industries. The Wafer butterfly valve produced is one of the more common types of valves in industrial pipelines. It is installed in the diameter direction of the pipeline and the rotation angle is between 0°-90°. When it is rotated to 90°, the valve is fully open. Wafer butterfly valve is characterized by simple structure, small size, light weight, and consists of only a few parts.

Pneumatic Threaded Ball Valve means a regular threaded ball valve with a pneumatic actuator. Pneumatic Thread Ball Valves are designed for quick opening and closing. The valve comprises of a split 2-piece body with PTFE seats. The pneumatic actuator offers single acting or double acting options. 

Welded Gate Valve is packed with corrosion agent avoids stem rusted. Deep Stuffing box guarantees long packing usage life..Welded seating ring effectively eliminates pipe leakage.

The Cryogenic Globe valve is composed of valve body, disc, stem, bonnet, handwheel and seal. The bonnet is of lengthened neck structure. It is characterized by double compression sealing structure composed of upper packing and lower packing. The medium flow path is low in and high out. The inlet channel of the valve body is below the sealing surface of the valve seat, and the outlet channel of the valve body is above the sealing surface of the valve seat.
