Product standards:

Design and manufacturing: JB/T5298 flange dimensions: JB / 79 structure length: JB/T5298

Pressure and temperature: GB9131 inspection and test: JB/T5298

Product features:

1. The seat of the sealing structure should be elastic pre-tightening force, either upstream or downstream seal seat sealing structure at the same time. Seating and sealing seal between content is always face to face.

2. The seat has self-cleaning function, and in the process of the valve opened or closed without being directly eroded by the airflow. The seat should consist of lubrication, no wear materials.

3. The valve actuator fault will not affect other parts of the valve, repair and replacement work can be conducted without dismantling the valve.

4. The yoke sleeve: aluminum bronze yoke sleeve needle thrust bearing, the greatest degree to reduce operating torque.

5. The valve stem: length of thread until the bracket; Pin and spot welding; Has the stability.

6. Pressure seal: simple structure, configuration of segmented retaining ring and mild steel silver plated gasket to aid disassembly and provide maximum bonnet seal.

7. Seat ring: welding seat ring is perpendicular to the flow channel, easy to maintain.

8. Actuators: these valves can be furnished with electric, pneumatic or hydraulic cylinder actuators. 12 the following configuration standards manual handwheel, oblique gear operator DN350 above configuration.

9. The yoke: fully fabricated yoke is seismically testing, easy maintenance and actuator mounting.

10. Gland: a two-piece, self-adjusting gland, avoid being pop up.

11. Integral backseat: hardfaced, the longest service life.

12. The disc: spring loaded discs can adjust themselves, reduce actuator torque requirements.

13. Overall: stop integrally cast carrier stop, positions carrier disc assembly, stable and reliable seating.
