Importance of Wedge Gate Valve Seals for Industrial Application 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.
