Fire-resistant & anti-static design.
pneumatic ball valve feature:
1. Design and manufacture according to the requirements of BS 5351.
2. Smallest liquid resistance for ball valve types.
3. Quick open and close speed, it may finish open and close by only rotating 90 degree.
4. Seat material follows PTFE or reinforced PTFE, with low friction coefficient, reliable sealing, open and close smoothly.
5. There is wipe action between ball and seats suitable to the medium of suspend granule.
6. Stem with upper and top entry structure is to avoid the stem blow out under the pressure of medium.
7. According to need of consumer may design anti-static, fire-safe, and lock system to prevent wrong operation.
8. Ball may be floating type and trunnion type in accordance with open and closing torque. The seat of trunnion ball valve is floating ball valve type which realize sealing by piston effection of medium pressure on seat and reduce open and close force.
