The operation of the gate valve is to perform a clockwise closing (CTC) or clockwise opening (CTO) rotary movement of the valve stem. When the valve stem is operated, the gate moves up or down on the threaded part of the valve stem.

Butterfly valves can be used in the shipbuilding industry, water supply and drainage, fire fighting, shipbuilding, water treatment and other systems.

These shut-off valves have one or more ports, and their valve bodies are spherical around the port area.

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.

A three-way ball valve is a three-way valve that allows fluid to flow to an alternative path to the hydraulic system. It allows fluid to enter and exit the valve through more than one port.

The valve seat is responsible for the movement of the valve gate. It can also help to further seal the flowing medium. For gate valves, there are two valve seats according to the type of gate. Take the wedge valve as an example, the valve seats on both si

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

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

For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

The easy operation, maintenance and versatility of the ball valve make it widely used in industry. This high-quality ball valve will be an excellent choice for shut-off and control applications.

In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.

The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

Control valves are an essential part of any piping unit. The basic function of these valves is to manage the flow of medium through different piping areas of a system. Ball and plug valves are two types of control valves that have similar functions and ar

The gate valve has a closing/closing mechanism. There is an upward internal gate device that allows the medium to flow and closes the valve downward. A distinctive feature of the gate valve is its straight passage, which reduces pressure loss and is easy

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.
