Function

2/2 Failsafe Closed

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays closed (Failsafe) requires power to open

2/2 Failsafe Open

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays open (Failsafe) requires power to close

2/2 Double Acting

2 ports (inlet/outlet) with 2 positions (Open/Closed) - power or air one side to move - power or air opposite side to return.

3/2 Normally Closed

3 ports with 2 positions. Power off inlet closed, outlet open to exhaust - power on inlet open to outlet with exhaust closed.

3/2 Normally Open

3 ports 2 positions. Inlet open to outlet with exhaust closed - power on inlet closed with outlet open to exhaust.

3/2 Universal

3 ports, 2 positions flow can be in any direction. Can be piped as 3/2 normally closed flow into inlet, 3/2 normally open flow into exhaust, 3/2 diverting flow into outlet.

Proportional / Modulating

Valve opens proportionally according to signal input, either 4-20mA, 0-10v or 0-5 volt. Example 4mA valve closed, 8mA 25% open, 12mA 50% open, 18mA 75% open and 20mA fully open.
