Frequently Asked Questions
What is the operating torque required for this valve?
The worm gear actuator reduces the required hand wheel torque significantly, making it easy to operate manually. Exact torque depends on line pressure and media, but the gear ratio ensures comfortable operation.
Is this valve suitable for seawater applications?
Yes, the valve is designed for marine piping systems and can handle seawater, freshwater, and many industrial fluids. Check material compatibility for specific chemical services.
What flange standard does this valve mate with?
The wafer type design fits between flanges conforming to PN10/16, ANSI Class 150, or JIS 10K standards. The flange diameter φD=256 mm and face-to-face L=60 mm are typical for DN200.
Does the valve come with a position indicator?
Yes, the gearbox is equipped with a visual open/close indicator showing the disc angle, allowing operators to verify valve position at a glance.
