The Metal Seated Wedge Gate Valve is purpose-built for zero-leakage isolation in large-bore water infrastructure systems. Its wedge design delivers a tight mechanical seal under high pressure, making it ideal for critical shut-off duties in dam outlets, raw water pipelines, and urban distribution networks.
Blackhall’s Series 3400 gate valve is optimised for buried service and low-maintenance operation in harsh environments. With a rugged ductile iron body and robust sealing surfaces, it performs reliably under variable flow and sediment conditions.
Proven in decades of field service, the wedge gate design is trusted by water authorities and civil contractors for dependable flow control, even after long periods of inactivity.
