1.Product overview

The opening and closing parts of the electric shut-off valve are plug-shaped clappers, the sealing surface is flat or conical, the valve flap moves linearly along the centerline of the fluid. Stem movement form, lifting rod (stem lift, hand wheel does not lift), there are lifting rotary rod (hand wheel with the stem rotating together, the nut is located in the valve body). Electric shut-off valve only applies to fully open and fully closed, does not allow for regulation and throttling.
