Our products are widely used in water treatment, building services, industrial processes, and infrastructure projects, serving markets in Hong Kong, the UK, and Japan. Each valve undergoes rigorous quality control and is available for manual operation or with a factory-preinstalled actuator. Actuators are installed, calibrated, and tested prior to shipment, ensuring faster and more reliable on-site installation while significantly reducing commissioning time.
The Non-slam check valve can be equipped with a counterweight optional with hydraulic damper cylinder. The closing time of the valve can be controlled, with limits, by metering the hydraulic flow in a damper unit.
Valve bodies and doors manufactured from ductile iron conforming to EN 1563-GJS-500-7. Seating surfaces. Valve Body is faced with gunmetal seat offers a durable metal-to-metal seating, suitable for wastewater service, supplemented by EPDM rubber O-rings for enhanced sealing integrity. ...
Ductile Iron body with epoxy coating or Full 316 Stainless Steel construction for excellent corrosion resistance against H₂S and acidic sludge.
Full Bore design ensures low pressure drop and minimised clogging in viscous sludge and biogas lines.
Available in Electric, or Pneumatic actuation with ISO 5211 mounting for reliable automation.
PTFE seats and blow-out proof stem provide bubble-tight sealing for both pressure and vacuum service.
ATEX / IECEx compliant options suitable for explosive biogas environments with long service life.
Solid wedge for small high-pressure valves
One-piece forged/cast construction (no welds)
Special heat treatment on both gate and stem T- head
High concentricity + lapped sealing surfaces = superior leak prevention
Lower torque and reduced seat wear
