Yister 3v 4v series pneumatic solenoid valve

時間:2024-09-04

Yister pneumatic solenoid valve 3V110/3V210/3V310/3V410 and 4V110/4V210/4V310/4V410 with a multi-colored aluminum body can be designed to function either with an internal or external pilot mechanism, and it can be configured to be normally open (NO) or normally closed (NC). 

1. **Body Material and Design:**
   - **Aluminum Body:** The valve body is made from aluminum, which is lightweight, corrosion-resistant, and durable.
   - **Multi-colored Finish:** The aluminum body could be anodized in various colors for aesthetic appeal or functional differentiation. Each section or component of the valve could be colored differently to indicate different functions or connections, such as red for the pilot section, blue for the main valve body, etc.
2. **Pilot Mechanism:**
   - **Internal Pilot:** The valve uses the process air pressure to move the valve spool or diaphragm. This means that a small solenoid controls the pilot air, which in turn operates the main valve. This is energy efficient as it uses the system’s pressure to assist in valve actuation.
   - **External Pilot:** An external source of air pressure is used to actuate the valve, separate from the system pressure. This setup might be necessary when the system pressure is too low or when the valve needs to operate independently of the process pressure.

3. **Valve Operation:**
   - **Normally Open (NO):** In this configuration, the valve remains open when the solenoid is not energized. The flow of air or fluid is continuous until the solenoid is activated, which closes the valve.
   - **Normally Closed (NC):** The valve remains closed when the solenoid is not energized. The flow of air or fluid is blocked until the solenoid is activated, which opens the valve.

4. **Applications:**
   - Such valves are used in various industrial applications where controlling the flow of air or gas is necessary, such as in pneumatic systems, automation equipment, or process control industries.

 5. **Customizations:**
   - **Size:** The valve size can be customized depending on customers demand.
