Design Features

Flanged / Buttweld / Threaded End Connections :RF (Raised Face) flanges conform to ASME B16.5, together with BW buttweld ends and NPT threaded ends, to suit various installation requirements.
 Full Bore Flow Passage :The seat bore matches the pipeline inner diameter with an extremely low flow resistance coefficient and low pressure drop, making it ideal for pigging operations.
 Blowout-Proof Stem :T-head or integrally forged structure prevents stem ejection caused by internal pressure, ensuring operational safety.
 Backseat Design :In the fully open position, the stem backseat seals against the bonnet, allowing online packing replacement to minimize downtime losses.
 Visual Position Indication :The rising stem extension directly indicates the opening degree; an opening indicator or limit switch can be optionally fitted.
 Low-Torque Operation :The resilient seat requires low closing force, and a gearbox is provided for large sizes to enable easy operation.
 Internal & External Anti-Corrosion Treatment :WCB surfaces are treated with epoxy coating, asphalt coating or rubber lining to extend service life.

Applications

Wastewater Treatment Systems :Featuring WCB body with epoxy anti-corrosion coating and EPDM seat, suitable for shut-off and regulation of sewage, sludge and rainwater.
 HVAC Systems :Used in cooling water, hot water and chilled water systems. Resilient seats provide tight shut-off to prevent energy loss.
 Oil Product Transportation Systems :NBR seats offer excellent oil resistance, ideal for shut-off service in pipelines for diesel oil, lubricating oil and fuel oil.
 General Industrial Water Supply & Drainage :Reliable shut-off for water, oil, gas and other media. Rising stem structure facilitates on-site operation and management.
 Marine Ballast Water Systems :WCB body with rubber lining, suitable for seawater ballast and bilge water systems.
