Pneumatically Operated Amplifier Valve Series 2L (Cv = .13)

Mod. 2LA-AM (Amplifier Valve), 3-way/2-position, Ports 1/8" BSPP, *(Will accept Pro-Fit® fittings)
The pneumatically operated amplifier valve is a 3-way/2-position normally closed valve, changing low pressure signals into 2 - 8 bar pressure signals.
The valve construction allows permanent reduced air consumption at rest.
Pilot pressure applied at Port 12 actuates valve and allows pressure (2 - 8 bar) to flow from inlet P to outlet A). 1 → 2. A constant "leak," or air consumption, occurs while unit is at rest from inlet 1 to atmosphere.

Technical Drawing


Basic Assembly/Circuit Guide
Basic Assembly/Circuit Guide Basic Assembly/Circuit Guide
The air signal from the receiver element (2LB-SR) will typically become the input pilot signal to the amplifier valve (2LA-AM). Receiver element (2LB-SR) will typically connect its port 2 (or "A"), to the amplifier valve pilot port 12.
Pilot pressure applied at Port 12 actuates valve and allows pressure (2 - 8 bar) to flow from inlet P to outlet A). 1 → 2. A constant "leak," or air consumption, occurs while unit is at rest from inlet 1 to atmosphere.
