Filter Valves
Purpose of speed regulating valve:
1. It is 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 should be applied to it, otherwise the valve body may be damaged and air leakage may occur;
2. When the speed regulating valve is closed, partial air leakage is allowed. Therefore, it is not recommended to use speed control valves where internal leakage is strictly prohibited.
