Wedge gate valves are a type of valve that are commonly used in various industries due to their reliable sealing and ability to withstand high pressure. This type of valve is designed with a wedge-shaped gate that is lifted and lowered to regulate flow. When the gate is lowered, it wedges itself tightly against the valve seats, creating a tight seal that prevents any flow from passing through.
Wedge gate valves can be divided into different categories based on their unique characteristics. Open stem wedge gate valves(Os&y) are designed with a stem that is exposed, making it easy to identify whether the valve is open or closed. Concealed stem wedge gate valves(NRS), on the other hand, are designed with a stem that is hidden, creating a sleeker appearance. Resilient valve disc wedge gate valves are made with a flexible disc that can bend and adjust to changing pressure, while rigid valve disc wedge gate valves are made with a solid disc that maintains its shape and position regardless of pressure changes.
| Wedge Gate Valve Material | Standard | Actuated Mode | Sealing method |
|---|---|---|---|
| cast iron cast steel stainless steel | API, DIN, JIS, KS, EN, BS, EAC, NF | manual operation electric actuator actuated of water/air/oil | Hard metal seal |
Advantages of Wedge Gate Valves
One of the key advantages of wedge gate valves is their ability to withstand high pressure. The angle of the wedge-shaped gate allows the valve to close tightly against the valve seats, creating a strong seal that can hold up even under high pressure. In addition, the stem of the wedge gate valve is often tempered and surface nitrided, providing excellent corrosion resistance and anti-scuffing properties.
Overall, wedge gate valves are a reliable and durable choice for a variety of applications, and their ability to withstand high pressure and provide a tight seal make them a popular choice in the oil and gas, chemical, and other industries.
