| Detailed Description: |
◆i-directional zero-leakage sealing. According with standard API 598 and ANSI/FCI 70-2 Class VI.
◆Optimized disc/shaft and inside cavity diameter makes it capable to achieve a high flow coefficient (Cv, Kv) and reduce the pressure loss. ◆The separate sealing ring design make it possible to adjust the sealing between sealing ring itself, ensuring the sealing performance is reliable. And the face to face contact between valve disc ring and valve body can ensure no friction and locking, so the valve torque is small. ◆The valve can achieve the security seal by the contact force from metal on metal instead of relying on the medium pressure and/or mechanical positioning. ◆The stable torque can ensure the reliability of Bi-directional sealing. ◆When open the valve, the pressure angle is greater than the frictional angle, the disc separates from the valve body sealing ring completely and immediately which can eliminate the friction between the valve body sealing ring and disc sealing ring, and extend its service life. ◆Using internal protection ring of the bearing to prevent intrusion of impurities, enhancing the reliability of the valve ◆The valve is suitable for various conditions with the detachable and replaceable seat. The valve body sealing ring and the disc sealing ring system can be replaced on site which can lower the maintenance costs. ◆The packing gland is composed of 2 parts to avoid the stem locking caused by offset, and allow the stem-packing regulate on site. ◆All parts of valve are interchangeable and replaceable. ◆The valve is “Intrinsically Fire-safe”. |
