- Constant torque output across full stroke.
- Balanced force vectors reduce side loading on valve stems.
- Operates in extreme environments: -40°F to 180°F (-40°C to 82°C).
- Suitable for slurry, natural gas and other applications.
- Easy adaptation to all quarter-turn valves.
- Simplified, Robust Design: Design enhancements to reduce potential leak paths, minimize maintenance, and extend service life. Fewer moving parts mean fewer failures and lower total cost of ownership.
- Seamless Integration with ValvTechnologies Valves: optimized to pair with ValvTechnologies’ valves, creating a fully integrated severe-service solution. This synergy ensures maximum performance and reliability across the entire valve-actuator package.
- Designed for severe service environments. Purpose-built for large bore isolation valves.
- Simplified, Robust Design: Opposite chambers in the actuator are connected by pressure equalizing passages in the upper and lower head.
- Simplified, Robust Design: The actuator produces well-balanced torque as hydraulic force pushes both of the rotary vanes away from the shoes
