FJ41H PN25~PN40 throttle cut-off emptying valve

Product features:
1. The valve is a new type of throttling, cut-off and empty-out product. The valve adopts the cage-shaped fan army throttling, with multi-stage throttling effect, obvious throttling effect, reliable sealing, easy operation and maintenance, etc.
2, the valve with a double seal (hard, soft seal) to seal reliable, hard alloy cover can be more resistant to airflow erosion, wear resistance, double seal can be achieved in the high-pressure gas medium conditions of zero leakage. 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 and a piston-type seal to ensure stable operation under the condition of full differential pressure, light and flexible opening and small opening and closing torque;
5. Throttle cut-off vent valve and double-acting throttle valve have throttling and cut-off at the same time (seal is zero leakage). The throttling part is separated from the sealing surface to reduce airflow erosion of the seal;
6. Double-acting throttling globe valve also has multi-stage throttling function, with large pressure difference of throttling, which can be applied to throttling and cut-off under high pressure;
7, packing with self-sealing capacity of v-shaped packing structure, no need to adjust, very easy to open and close. The packing box is equipped with auxiliary seal grease injection structure, which makes the valve packing seal performance reliable.
8. The valve can be maintained online, and the pipeline can replace a series of wearing parts such as packing under pressure;
9. The valve has a large drain hole at the bottom of the valve, which should be opened when necessary to clean up the dirt in the valve.
Scope of use: the product can be used for refining, chemical, liquefied gas. Oil and gas storage and transportation industries. No Information
