We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

The plug or disc is an important part of the valve. It is connected to the valve stem and can be used for throttling.

The three-piece ball valve uses the same dynamic multi-ring gland system as the needle valve to provide higher strength and integrity. When combined with the blowout prevention rear seat valve stem, it can ensure that it can withstand all operating proces

We are the world\'s most popular supplier of gate valves in China because we provide high-quality service and high-quality gate valves. Due to the top quality of our gate valve, it is suitable for a wide range of industrial and commercial applications. We

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

Cast iron gate valves are used in commercial and industrial applications. Its typical services include: hot and cold water, HVAC, steam, gas and other general utility services.

The valve cover provides a leak-proof closure to the body. The threaded valve stem part will pass through a hole that has a thread similar to the valve cover, and the valve stem with the threaded part extends into the same hole as the valve cover thread.

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

Gate valves serve to cut the medium flow in the piping system, widely used in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.

The pipeline gate valve is designed to meet the long-distance transportation service of crude oil and natural gas. It is designed in accordance with API 6D and has DBB function, so the valve can provide two-way switching services. Our straight-through con

Because of its ability to cut off liquids, gate valves are often used in the petroleum industry. For extremely viscous fluids, special valves commonly called knife valves are used to cut off the liquid. A typical gate valve is designed to be fully open or

Its working principle is to lift or press a rectangular or circular gate connected by the valve stem to the fluid path by rotating the handle wheel clockwise and counterclockwise.

The structure of the wafer butterfly valve is formed by the central disc rotating 90 degrees in the valve body. Using the drive type, the flow of fluid can be stopped, adjusted or started. In the wafer connection, the valve is installed between pipe flang

The closing function of gate valves is very good. They provide laminar flow with minimal pressure loss.
