The sanitary pneumatic diverter valve is only one of the many types of valves, and the amount is relatively larger than other types of valves. The sanitary pneumatic diverter valve is a control component in the fluid delivery system, which can be used to control air, water, steam, and various corrosive media. The flow of various types of fluids, such as mud, oil, liquid metal and radioactive media, has the functions of cut-off, regulation, diversion, prevention of backflow, stabilization, diversion or overflow and pressure relief.

What is the working principle of sanitary pneumatic diverter valve?
1. The sanitary pneumatic diverter valve is installed on the oil return path of the two actuators to combine the oil return flow of the two loads to return the oil;
2. The two flow sensors of the sanitary pneumatic diverter valve share the inlet pressure P0. The greater the flow rate Q1 (or Q2) of the flow sensor, the lower the outlet pressure P1 (or P2); the two flow sensors of the sanitary pneumatic diverter valve share the outlet pressure. O, the greater the flow rate Q1 (or Q2) of the flow sensor, the higher the inlet pressure P1 (or P2). Therefore, the pressure feedback direction of the collecting valve is just opposite to that of the diverting valve;
3. The sanitary pneumatic diverter valve can only guarantee synchronization when the actuator returns to the oil.
The sanitary pneumatic diverter valve does not work, what are the possible causes and symptoms?
1. The sanitary pneumatic diverter valve has no signal and no gas source. ①The gas source is not turned on, ②The air pipe of the sanitary pneumatic diverter valve is blocked or the filter and the pressure reducing valve are blocked due to the freezing of the water in the gas source in winter, ③The compressor is malfunctioning; ④The main pipe of the gas source is leaking.
2. The sanitary pneumatic diverter valve has air source but no signal. ①The regulator is faulty, ②the signal tube is leaking; ③the bellows of the positioner is leaking; ④the regulating mesh is damaged.
3. The sanitary pneumatic diverter valve has no air source. ①The filter is blocked; ②The pressure reducing valve is faulty I③The pipeline is leaking or blocked.
4. The sanitary pneumatic diverter valve positioner has air source but no output. The orifice of the positioner is blocked.
5. The sanitary pneumatic diverter valve has signal but no action. ①The valve core falls off, ②The valve core is stuck with the society or the valve seat; ③The valve stem is bent or broken; ④The valve seat and valve core is frozen or burnt dirt; ⑤The actuator spring is rusted due to long-term use.
What are the structural characteristics of sanitary pneumatic diverter valve?
The sanitary pneumatic diverter valve is composed of a multi-spring pneumatic diaphragm actuator and a three-way confluence (diverter) valve with a cylindrical thin-walled window-shaped valve core. It has simple structure, light weight, sensitive action, and good flow characteristics. It can be equipped with electric valve positioning or pneumatic valve positioner, which can realize automatic adjustment and control of process pipeline fluid medium. It is widely used to control gas, liquid, steam and other media The process parameters such as pressure, flow, temperature, liquid level and other parameters are kept at given values. The sanitary pneumatic diverter valve is suitable for working conditions where a fluid is divided into two ways through a three-way valve or two fluids are combined into one fluid through a three-way valve.
