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 gate valve is an energy-saving valve option because the direction of movement or gate is perpendicular to the direction of medium flow. Therefore, less power is consumed when opening or closing the gate valve compared to the shut-off valve. Because of

Our company can also provide customized valve services according to your requirements. Feel free to contact us for more information or to request a complete product category.

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

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

The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use. These qualities make them an excellent choice for shut-off applications where they are generally more popular than ga

Gate valves are widely used in all types of applications, suitable for above-ground and underground installations. Especially for underground installations, it is important to choose the correct type of valve to avoid high replacement costs.

The valve cage is a part of the valve, which surrounds the valve plug and is located in the valve body. The valve cage is the main component that determines the fluid flow in the valve. As the stopper moves, more cage openings are exposed and the flow rat

The gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.

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 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

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

Globe valves are considered the industry standard for control valves because they are good at regulating flow, while ball valves are more suitable for on/off control without pressure drop.

In a system with irregular changes in high temperature, the gate valve will leak due to the load in the valve end pipe.

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