J641H Pneumatic Globe Valve basic information
J641H Pneumatic Globe Valve produced and sold by Baigang valve group opening and closing pieces of plug-shaped flap, the sealing surface was flat or tapered surface, the valve flap along the center line 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). Globe valve only applies to fully open and fully closed, does not allow for regulation and throttling.
J641H Pneumatic Globe Valve valve features
