2.This Throttle Stop valve uses hard and soft seals to get it reliably sealed, the carbide alloy sealing face becomes more resisting to the gas-flow erosion and more wearable and the dual-seal can realize zero-leakage under the high pressure gas medium, leaving a long duration of the valve.

3.The sealing surface of the Throttle stop valve seat ring uses a taper seal, benefit to the self-clean of the dirt absorbed onto the face.

4. A balancing hole and a piston type seal are set on the throttle stop valve's disc, making sure of a stable operation, light and flexible open-close and a small open-close torque.

5. Throttle, stop and draining valve and the dual-action type throttle valve have both throttle and stop(Zero-Leakage with the seal) actions, with the throttle portion separated from the sealing face so as to reduce the erosion of the gas flow to the seal.

6. The dual-action type throttle valve also features a multiple-stage throttle function and a big throttle pressure differential and is suitable for throttle and stop under a high pressure.

7. The packing uses a V-Type Packing structure with self-seal ability, without need to adjust and with both open and close extremely light. Ans assisting sealing grease injector is set in the packing place to have its sealing performance reliable.
