Overview
J6B7Y throttle valve throttle opening and closing pieces of plug-shaped flap, the sealing surface was flat or tapered surface, the valve flap along the centerline of the fluid for linear motion. 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). Bellows globe valve only applies to fully open and fully closed, does not allow for regulation and throttling.
Structural features
