Details
Featuring a premium EPDM encapsulated ductile iron wedge, this full-bore valve delivers 100% bi-directional tightness to ensure zero leakage and total system isolation. The clean, straight-through design minimises fluid friction and head loss, optimising overall pumping efficiency across infrastructure networks.
Built for demanding service environments, the valve stem is repackable under full pipeline pressure, allowing maintenance teams to replace seals without shutting down the main line or causing costly project downtime. The low torque mechanical design ensures smooth, easy manual actuation and dramatically extends the operational lifespan of internal components.
Equipped with robust raised face flanges rated for PN10 and PN16 configurations, this valve ensures seamless bolt hole alignment with standard UK pipework systems. The unit is available in sizes ranging from DN50 to DN300 and can be configured with either a manual handwheel for above ground access or a standard top cap for underground extension spindle operation.
Every component of this gate valve is selected for long-term durability in underground or harsh service environments. The main body, bonnet and operating top cap are cast from high tensile ductile iron, providing superior impact resistance compared to traditional cast iron.
The internal stem is machined from premium stainless steel to prevent rust and seizure over years of static operation. The internal wedge is fully encapsulated in drinking water grade EPDM rubber, ensuring excellent sealing elasticity without degrading over time.
Combined with a low friction thrust bearing mechanism, these components allow smooth operation under tough network pressures.
