Slurry letdown and vent angle control valves are the most critical control valves used in the discharge pipe between autoclave in oxygen pressure leaching workshop and flash tank, being able to affect the normal operation and stability of the device as well as the production cost. In order to meet the customer's use requirements, our Slurry letdown and vent angle control valves have made reasonable design in structure and material selection.
- Valve chamber cushioning design;
When the pulp passes through the valve core, it must first be decompressed to facilitate the cushioning effect. With cushioning design, the inner chamber can reduce the medium pressure instantaneously, and the pulp will not wear and wash the valve body too heavily. - No dead band design at turning position;
the no dead band design can keep the fluid flowing smoothly, without frontal erosion of shell wall and inner parts due to sharp turning. - Special Materials; The plug and seat are made of WSV alloy material with strong cavitation resistance, which can effectively reduce the damage of the plug and seat caused by cavitation. Therefore, our Slurry letdown and vent angle control valves can work longer in high-speed flow medium.
- Hawking Metal Surface Processing Technology;
The surface roughness of the elements processed by Hawking Machine is less than Ra0.2, which improves its surface hardness and wear resistance, reduces the wear of sealing filler and the valve torque, and makes the seal of dynamic sealing part more reliable. - Spring loaded to compensate seal automatically;
The belleville spring is used to load the connecting bolt between packing and gland flange to prevent abnormal change of pressure and temperature in pipeline. The belleville spring can automatically compensate for and protect sealing.
