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

There are many types of gate valves, such as full bore gate valves, parallel disc gate valves, solid wedge gate valves, flexible wedge gate valves, split wedge gate valves, vertical stem gate valves, and non-vertical stem gate valves.

Excellent double-sided sealing function, test zero leakage. Excellent double-sided sealing function, test zero leakage. Simple structure, small size, light weight, fast opening and closing, and fixed operation. Suitable for various medium working conditio

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.

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.

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.

Concentric design wafer butterfly valve, with no back structure, rubber welded valve body, replaceable elastic seat, streamlined disc, integrated stem

Ball valves are more effective in forming tight seals and have higher reliability and life than gate valves, but they are more expensive. They are often used to shut down and control applications. Because the ball valve can be opened and closed instantane

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

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

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

High-performance stainless steel butterfly valves are one of the most widely used butterfly valve types in processed food-grade products. They are also used to treat corrosive fluids. Stainless steel butterfly valve adopts SS304, SS316 or SS316L body mate

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.

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.

We test every valve during the production process, and carry out quality control in all processes such as forging, processing, and assembly to ensure quality.
