How do wedge gate valves work?
A wedge gate valve uses a tapered wedge‑shaped disc that fits tightly between two inclined seats. Turning the stem raises or lowers the wedge, providing isolation with minimal pressure drop when fully open.
Advantages of wedge gate valves...
• Tight shut‑off for isolation
• Minimal pressure drop when open
• Suitable for bidirectional flow
• Durable in high‑temperature service
• Long service life with infrequent operation
