Series 21 Solenoid Pilot Controlled Vacuum Valves 2/2 Valves Piping 2/2 Normally Closed or Normally Open Valves Pipe the unit into the system by connecting the vacuum source or pump to the normal air pressure inlet port (port 1). The normal outlet port is the work port (port 2). Note: 2/2 vacuum valves provide only on/off control and do not have an exhaust function.

Series 21 Solenoid Pilot Controlled Full Vacuum Valves Full Vacuum — 3-Way Normally Closed Full Vacuum — 3-Way Normally Open This valve functions as a normally open valve. Pipe the unit into the system by connecting the vacuum source or pump to port 3, the normal exhaust. Leave port 1 open to atmosphere, and the normal outlet remains as the work port (port 2). This valve functions as a normally closed valve.
