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 valve seat of the gate valve is either provided integrally with the valve body or adopts a seat ring structure. The valve seat provided by the valve seat ring structure can be screwed into place or pressed into place and sealed and welded to the valve

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 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

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

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.

Forged steel gate valves are available in three bonnet designs. The first design is a bolted bonnet with male and female joints and spiral wound gaskets, made of F304/graphite. Ring joint gaskets are also available on request. The second design is a welde

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.

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

Ball valves are widely used in petroleum and natural gas, chemical and petrochemical, food industry, water supply, water treatment, building construction, light industry, power generation, pharmaceuticals, biotechnology, laboratory equipment, marine and o

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.

Floating ball valves are widely used in various industries and attract more end users to replace gate valves and globe valves in cryogenic applications.

Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

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.

The main difference between these two types is the way they are closed. The stop valve uses a plug (stem) that closes against the flow, while the ball valve has a gate (ball) that can close the entire flow. The stop valve is suitable for adjusting the flo
