Filter Valves
Purpose of speed regulating valve:
1. It is strictly prohibited to use tools other than hands to turn the adjustment cover. When the adjusting cap is at the upper and lower limit positions, no additional external force may be applied, otherwise the valve body may be damaged and air leakage may occur;
2. When the speed regulating valve is closed, some air leakage is allowed. Therefore, it is not recommended to use the speed control valve in situations where internal leakage is strictly prohibited.
