Center line clamp butterfly valve

The center line butterfly valve is mainly composed of valve body, valve plate, valve stem and sealing materials. It realizes the opening and closing of the fluid by rotating the valve plate, which has excellent sealing and easy operation.

On the folder butterfly valve

Middle-line double-flanged butterfly valve combines the characteristics of middle-line butterfly valve and double-flanged connection, using the butterfly plate as the opening and closing part, through the rotation of the butterfly plate to achieve the opening and closing operation.

Clamp butterfly valve

The clamp butterfly valve is an industrial product suitable for conveying various corrosive and non-corrosive fluid media pipelines in engineering systems, mainly used to regulate and cut off the flow of media.

Flange butterfly valve

The French butterfly valve, also known as the flanged butterfly valve, is a valve that controls the flow of fluid by rotating the disc-shaped butterfly plate. Its structure is mainly composed of valve body, control plate, valve stem, sealing ring and other components. On the body of the French butterfly valv

Anticorrosive butterfly valve

Split type anticorrosive butterfly valve is a special type of butterfly valve, its main feature is that it has good corrosion resistance, suitable for all kinds of corrosive media pipeline system. The split butterfly valve, also known as the αβ valve, consists of an active valve and a passive valve, using the split butterfly valve technology. It uses the circular butterfly plate as the opening and closing part, and realizes the opening and closing of the fluid through the rotation of the butterfly plate.

Industrial butterfly valve

An industrial valve is a switching or regulating device installed in a pipeline to control a fluid (including liquid, gas, steam, etc.). It has a wide range of applications in the industrial field, and plays a key role in controlling the flow of pipeline media, preventing backflow and realizing the adjustment and distribution of fluid.

Double eccentric butterfly valve

Double eccentric butterfly valve, also known as high-performance butterfly valve, is mainly composed of valve body, valve plate, valve core, seat, valve cover, support rod, shaft head, cover, detector, gasket body and other components. Its structural feature is that the valve stem axis deviates from the center of the butterfly plate, but also deviates from the center of the body, this double eccentric design makes the valve after opening the butterfly plate can be quickly removed from the seat, greatly eliminating the unnecessary excessive squeezing and scratching phenomenon between the butterfly plate and the seat.

Lug butterfly valve

Middle line lug type butterfly valve is a fluid control valve, the stem axis, the center of the butterfly plate, the center of the body is located in the same position, that is, the middle line position. The lug design refers to the connection between the valve stem and the valve plate in the form of lugs to enhance the support and stability of the valve stem.

Split knife gate valve

Split knife gate valve, also known as split structure knife gate valve, is a knife gate valve with a split body design. Knife gate valve, also known as knife gate valve, is a valve that controls fluid flow by rotating knife gate. The split body design means that the body is divided into two parts, which are bolted or other fasteners together after fabrication to form a complete body.

Gate valve of metal

Metal gate valve, as a fluid control valve, mainly through the vertical lift of the gate to achieve fluid opening and closing and regulation. Its structure is mainly composed of valve body, valve cover, support, valve stem, gate, seat and other parts. The material of metal gate valve is mostly metal, such as carbon steel, stainless steel, etc., to adapt to different working environments and media.

Vertical check valve

The vertical check valve works by overcoming the resistance of the spring through the medium pressure at the inlet of the pipe to open or close the valve. Specifically, when the medium flows downstream, the valve is opened by the thrust of the medium; When the flow direction of the medium is reversed, that is, when the pressure of the medium at the inlet is lower than the pressure at the outlet, the spring pushes the spool to the seat, so that the valve is closed and the medium is prevented from flowing back.

Turn the check valve

Swing check valve is an important fluid control valve, which is mainly used to prevent the backflow of media in the pipeline. The working principle of the swing check valve is that when the pipeline fluid flows in the specified direction, the disc inlet pressure is higher than the outlet pressure, the disc is pushed away from the seat, and the valve is open. When the pressure difference between the two sides of the valve disc decreases to a certain level, the valve disc falls and returns to the closed state, preventing the backflow of the medium.

Double plate check valve

A double-plate check valve is a valve consisting of two movable plates connected by a spring. This valve allows the medium to flow freely in one direction, and when the medium tries to flow in the opposite direction, the double plate will quickly close under the action of the spring to prevent backflow. It is mainly composed of valve body, valve cover, valve disc (two movable plates), spring, seat and other components.

Ball valve

The ball valve is a valve whose opening and closing parts (spheres) are driven by the stem and rotate around the axis of the ball valve. It is mainly used for cutting off, distributing and changing the flow direction of the fluid.
