Design Standard

1. Design and Manufacturing: As per API 6D or API 608 
2. Face to face: As per ANSI B16.10 
3. Flange: As per ANSI B16.5 
4. Butt welding: As per ANSI B16.25 
5. Inspection and Test: As per API 6D or API 598 


Design Structure and Features 

1. Design and manufacture according to the requirements of ANSI B16.34, API 600, API 6D. 

2. Smallest liquid resistance for 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. The Ball Valve 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 mounted ball valve is floating type which realize sealing by piston effection of medium pressure on seat and reduce open and close force.
