When we refer to EX-Air Valves we are talking about electrically controlled shuttle valves, as opposed to a pump that uses a c-spool piloted by an air signal from the pilot valve. The EX-Air Valve is available on all pumps except the NDP-15 series pumps.
This type of valve can be directly mounted on the pump or remotely mounted. It is available in single or dual solenoid versions in 12VDC, 24VDC, and 115VAC.
A pump equipped with this type of valve is used for metering and batch control. It is used with our YSC-3 controller or can also be used with a PLC (Programmable Logic Controller).
The standard Ex-Air valve that is used with the YSC-3 controller is a 12VDC single solenoid valve.
