Features and Operation
- Direct acting, normally closed operation with responsive switching.
- No additional oil lubrication is required.
- Multiple valves can be assembled together to save installation space.
- A manual override assists with installation and commissioning.
- Several standard voltages are available. The voltage for this model is specified above.
Symbol ports: P is the air inlet, A is the working port and R is the exhaust. In the catalog’s normally closed symbol, P to A is closed and A is connected to R when de-energized. When energized, P connects to A. The spring returns the valve to its normal position.
