API Fixed Worm Gear Ball Valve

API Fixed Worm Gear Ball Valve
1. Ball Valve Smallest liquid resistance for valve types.
2. API Fixed Worm Gear Ball ValveQuick open and close speed, it may finish open and close by only rotating 90 degree.
3. API Fixed Worm Gear Ball Valve Seat material follows PTFE or reinforced PTFE, with low friction coefficient, reliable sealing, open and close smoothly.
4. API Fixed Worm Gear Ball Valve is wipe action between ball and seats suitable to the medium of suspend granule.
5. API Fixed Worm Gear Ball Valve Stem with upper and top entry structure is to avoid the stem blow out under the pressure of medium.
6. According to need of consumer may design anti-static, fire-safe, and lock system to prevent wrong operation.
7. API Fixed Worm Gear Ball Valve`s Ball may be floating type and trunnion type in accordance with open and closing torque. The seat of trunnion mounted ball valve is floating type which realize sealing by piston effection of medium pressure on seat and reduce open and close force.
