What can be used to replace solenoid valves
Thread Content
I have a reaction tank, and I want to use limit switches to control the opening and closing of valves; I chose solenoid valves for this purpose. However, the pressure in the equipment is 3.0 MPa and the temperature is 233 degrees Celsius, and such solenoid valves are not available currently. I’m seeking advice from everyone – are there any other devices that can serve as a substitute? Urgent!
The solenoid valve is used to control the air supply system of the control valve, and it has nothing to do with \"equipment pressure of 3.0 MPa and temperature of 233 degrees Celsius\".
The limit switch is connected to the control room, while the solenoid valve is used to control the opening and closing of the valve
What medium are you using? Generally, a two-way valve will suffice; either electric or pneumatic types can be used. The difference is that pneumatic valves respond faster while electric ones respond more slowly.
Our company manufactures such solenoid valves; the maximum pressure they can handle is 6.4 MPa, and the maximum temperature is 450°C. The switching time is ≤1 second. The model is ZCZH-32BF, and the materials used are 304 or 316 stainless steel. You can contact us directly.
A limit switch can be added to the pneumatic ball valve
Using solenoid valves for such a long time affects their lifespan
In fact, solenoid valves are not only installed on control valves or on-off valves to regulate instrument air; there are also solenoid valves that are mounted directly on the pipelines
I did find one for sale, but my boss thought it was too expensive – over three thousand per unit. Are there any other cheap options to consider? Can the ball valve on the 6th floor be automated? The limit is at the bottom of the horizontal tank, while the air inlet is on top – how can they be connected?
Solenoid valves – what can the control switch be used for and why needs it to be replaced? Pneumatic valves also allow for fast switching
