Inspection before valve installation ① Carefully check whether the valve model and specifications meet the drawing requirements. ② Check whether the valve stem and valve disc are flexible in opening, and whether they are stuck or skewed. ③ Check whether the valve is damaged and whether the thread...Read more -
The regulating valve is leaking, what should I do?
1.Add sealing grease For valves that do not use sealing grease, consider adding sealing grease to improve the valve stem sealing performance. 2. Add filler In order to improve the sealing performance of the packing to the valve stem, the method of adding packing can be used. Usually, double-layer...Read more -
Regulating valve vibration, how to solve it?
1. Increase stiffness For oscillations and slight vibrations, the stiffness can be increased to eliminate or weaken it. For example, using a spring with a large stiffness or using a piston actuator is feasible. 2. Increase damping Increasing damping means increasing friction against vibration. Fo...Read more -
