The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

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

Push-in joints do not require solder, glue, unions or tools. Corrosion resistant to extend service life, designed for drinking water distribution and circulating heating 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.

Gate valves can be divided into two main types: parallel and wedge. The parallel gate valve uses a flat gate between two parallel valve seats. The popular type is a knife gate valve with sharp edges on the bottom of the gate.

The gate valve is composed of three main parts: the valve body, the valve cover and the valve trim. The body is generally connected with other equipment through flange, thread or welding connection. The engine cover containing the moving parts is usually

The valve is bidirectional and can be installed in any direction relative to the water flow. The valve will control the flow equally in either direction. In order to obtain the best valve control and stable performance, the inlet straight pipe section sho

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.

Gate valves are used in a variety of industrial applications, including oil and gas, pharmaceuticals, manufacturing, automobiles, and ships.

This kind of gate valve is more flexible, because its gate can move up or down, there is no obstacle to the flow of fluid or gas, thus ensuring less friction.

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.

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 main difference between ball valves and globe valves is the way they close. A ball valve has a stem and a ball, which rotate horizontally and are usually called "rotary" valves. The globe valve has a stem and a plug, which stroke linearly, a

The valve body and bonnet are made of castings and are connected by flange joints. The seat surface of the valve seat and the wedges conform to the API 600 standard. The seat ring is welded into the valve body.

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.
