Vacuum Valve Technology Pneumatic 2/3-Way Vacuum Switching Valve MVV
1. Introduction and application
- The valve is a 2/3-way pneumatically controlled cone valve with a normally open or closed type.
- The valve is suitable for applications where air needs to be rapidly introduced into a vacuum system to restore atmospheric pressure.
2. Benefits.
- Control of vacuum on/off or venting function
- Suitable for lines with large nominal flow rates
- Short opening and closing times
3. Design
- The body is made of aluminum alloy;
- (4) is the compressed air inlet;
- When the valve is used normally open, (1) is the vacuum pump interface, (2) is the pressure relief port, and (3) is the action port.
- When the valve is used normally closed, (1) is the pressure relief port, (2) is the vacuum pump interface, and (3) is the action port.
