What are the positive and negative effects of a regulating valve?
The positive and negative effects of a regulating valve are relative to the actuator of a pneumatic diaphragm regulating valve, where the upper part of the diaphragm is filled with air and the push rod moves downward, known as the positive effect. The lower intake and upward movement of the push rod are called reactions.
The air opening and closing of the regulating valve are relative to the entire regulating valve system. As the signal increases, the valve gradually opens into an air open valve, and as the signal increases, the valve gradually closes into an air closed valve. When there is no signal, the pneumatic valve is in the closed state and the pneumatic valve is in the fully open state.
