Welding the valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. The movement of the stem form, there is lift rod type (the stem lift, hand wheel is not up and down), but also the lifting of the rotating bar type (hand wheel and the valve stem rotation, the nut is located in the valve body). Bellows valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
Simple structure, easy manufacture and maintenance.
Working schedule is small, and the opening and closing time is short.
Good sealing, sealing surface friction between the small, long life.
