The pneumatically operated amplifier valve is a 3/2 N.C. valve, changing low pressure signals into 2 - 8 bar pressure signals.
The valve construction allows permanent reduced air consumption at rest.

Both the sender and receiver should be supplied with filtered, non-lubricated compressed air.
The sender requires a supply pressure of 0.3 - 2 bar. In the case of the receiver (max 8.7 psi), this is done in order to prevent the danger of contamination. The air jet from the sender interrupts the free outflow of the air jet at the receiver. A back pressure is produced which generates a control pressure at outlet A of the receiver. This pressure signal is typically sent to an amplifier valve. If an object breaks the air jet between the sender and the receiver, the signal drops to zero.

The air signal from the receiver element (2LBSR) 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.
