Features

Engineered for leak-free performance and cost-efficiency, combining a solid unibody structure with reliable motorized actuation

✅Unibody Design for Zero External Leakage
The valve body is cast as a single solid unit without bolted joints or body seals. This "One-Piece" construction removes the potential leak paths found in 2-piece or 3-piece valves, offering superior safety for critical utility lines.
✅Reliable Motorized Actuation
Integrated with the DELCO Electric Actuator, featuring a high-torque motor and hardened gear train. It supports rapid On/Off operation or precise 4-20mA positioning, complete with IP67 weatherproofing and a visual indicator for clear status monitoring.
✅Economical Reduced Port Configuration
The valve utilizes a reduced bore (venturi) design. This allows for a lighter, more compact valve body and lower operating torque requirements, significantly reducing both the valve cost and the actuator size without compromising essential flow rates for water and steam.
✅Durable WCB/Stainless Steel Materials
Constructed from heavy-duty Cast Steel (WCB) for high-pressure durability or Stainless Steel (304/316) for chemical resistance. Standard features include a blowout-proof stem and anti-static design for industrial safety.
✅Universal Flange Integration
Designed for global versatility, the integral flanges are machined to meet ANSI 150/300, DIN PN16/40, and JIS 10K/20K standards, ensuring seamless retrofitting into existing international piping systems.
