Product Features

​
☆ Compact and Lightweight Body Design

Optimized structural configuration ensures reduced weight and space-saving installation without compromising strength.

☆ Concentric Disc Design (Pinned or Pinless Options Available)

Precisely machined concentric disc ensures reliable sealing performance and stable torque characteristics. Available in pinned or pinless construction to suit different application requirements.

☆ Quarter-Turn Fast Operation

90° rotary operation enables rapid opening and closing, suitable for automated and manual actuation systems.

☆ Bidirectional Tight Shut-Off

Provides reliable sealing performance in both flow directions, ensuring zero-leakage under specified pressure ratings.

☆ Corrosion-Resistant Coating Options

Available with rubber-lined disc, fusion bonded epoxy (FBE) coating, or other anti-corrosion treatments for extended service life in aggressive media.

☆ Full Bore / High Flow Capacity

Optimized flow path design ensures high Cv value and minimal pressure drop.

☆ Replaceable Seat Design

Renewable seat structure allows convenient maintenance and extended service life.

☆ Economical Alternative

Provides a cost-effective shut-off solution compared to gate valves, globe valves, and ball valves, particularly in large-diameter applications.
