1, Throttling cut-off vent valve is a new type of throttling, cut-off, vent products, throttling cut-off valve adopts cage fan legion throttle, with multi-stage throttle effect, throttle effect is obvious, reliable sealing, convenient operation and maintenance, etc
2, The valve adopts double seal (hard and soft seal) to make the seal reliable, hard alloy cover can be more resistant to airflow scouring, wear resistance, double seal can achieve zero leakage under the condition of high pressure gas medium. Long service life of valve
3, The sealing surface of the valve seat adopts taper seal, which is conducive to cleaning the dirt attached to the sealing surface of the valve itself
4, The valve disc is provided with a balance hole, piston seal, to ensure the stable operation under the condition of open/close full pressure difference, open light and flexible, open and close torque is small
5, Throttling cut-off vent valve and double acting throttle valve at the same time with throttling and cut-off (seal is zero leakage) action throttling part and sealing surface separate, in order to reduce the airflow of the seal scouring
6, Double acting throttling globe valve also has multistage throttling function, throttling pressure difference is large, can be used for high pressure throttling and cut-off
7, Packing with self-sealing ability of the V-shaped packing structure, no need to adjust, open and close very light. Packing box is equipped with auxiliary sealing grease injection structure, so that the sealing performance of the valve packing is reliable
8, Throttle cut-off vent valve can be online maintenance, pipeline can be under pressure to replace a series of vulnerable parts such as packing
9, Throttling cut-off valve at the bottom of the valve is provided with a large sewage hole, if necessary to open, clean up the dirt in the valve.
