① Large, multiple eccentric structure,butterfly-shaped disc result in very low flow resistance.
② The oil dashpot provides a slow closure of disc and prevent sealing element from damage.
③ Angled seat design results in a short closing time & stroke and completely prevent pump from water hammer.
④ Flow area 40% greater than nominal pipe size. Almost no pressure drop produes when medium moves the disc. The tilting disc check valve conserves energy and provides ultra low headloss characteristics of any check valve available today.
⑤ The short disc stroke that is less than 1/2 of swing check valve’s results from an angled seat of only 40°. The short stroke reduces the closing time of the valve disc.
⑥ An unique bottom or top mounted oil dashpot allows the disc slowly close for the final 5° closure. It allows the disc to open and close freely without restriction and conserves a great amount of energy.
⑦ Working without attendance of person and without control of external signal. As an independent device, the oil dashpot can be adjusted according to working conditions without control of hydraulic and power supply. Fetures in maintenance-free,enviromental
protection, energy-saving and lowest operating cost.
⑧ Suitable for horizontal or vertical installation
