The Tecflow flanged resilient seated gate valve is a heavy duty water management valve engineered to BS 5163 standards for maximum reliability. Manufactured from robust ductile iron with a durable 250 micron epoxy coating, this premium isolation valve is fully WRAS approved, making it safe and certified for use with UK potable water mains, sewage networks, and commercial irrigation systems.

Zero leakage

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.

Easy maintenance

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.

Flange compatibility

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.
