Sender and Receiver Element Series 2L
Sender and Receiver Element Series 2L

Mod. 2LB-SE (Sender)
Mod. 2LB-SR (Receiver)


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.

Series 2L Pneumatically Operated Amplifier Valve
Series 2L Pneumatically Operated Amplifier Valve

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.

Series 3 Air-Pilot Operated Valve
Series 3 Air-Pilot Operated Valve

1/8” NPTF, 3-way/2-position & 5-way/2-position
1/4” NPTF, 3-way/2-position, 5-way/2-position, 5-way/3-position,and dual 3-way/2-position valves.


The pneumatically operated,3-way/2-position, 5-way/2-position Series 3 valves have been designed with different methods of return: An Air-Pilot with mechanical spring, Air-Pilot return, or Air-Pilot with bias override return. This is possible due to the type of design consisting of a balanced spool, which means that it can be used for a very wide range of applications. (including reverse porting).
The 3-way/2-position valves are normally closed in the rest position when the pressure is supplied at P, and are normally open when the pressure is supplied at R, the use of A remaining unchanged. Moreover, the 5-way/2- position valves can be supplied via the ports R and S with two different pressures if a cylinder must be operated using a delivery pressure different from the return pressure.
On the valve series 3, two additional holes permit assembly onto the manifold CNVL without the use of a banjo bolt.
*See manifold codes at the end of this section.
New versions of this valve have expanded the range to higher flow 1/4” ported valves as well as dual 3-way/2-position valves. 1/8” and 1/4” valves can be mounted on a common manifold by means of a transition plate.

Series 4 Air-Pilot operated valves

1/8”, 1/4” NPTF, 3-way/2-position
5-way/2-position; 5-way/3-position
1/2” NPTF 5-way/2-position


The pneumatically operated,3-way/2-position, 5-way/2-position Series 4 valves have been designed with different methods of return:
an Air-Pilot with mechanical spring, Air-Pilot return, or Air-Pilot with bias return. This is possible due to the type of design consisting of a balanced spool, which means that it can be used for a very wide range of applications. (including reverse porting)
The 3-way/2-position valves are normally closed in the rest position when the pressure is supplied at P, and are normally open when the pressure is supplied at R, the use of A remaining unchanged. Moreover, the 5-way/2-position valves can be supplied via the ports R and S with two different pressures if a cylinder must be operated using a delivery pressure different from the return pressure.
On the Series 4 valves, two additional holes permit assembly onto the manifold CNVL without the use of a banjo bolt.
* See pages at end of sections for manifold options.
Key - Series 4 valves incorporate a double lip (Z) seal against the spool. This seal design has improved wear and sealing properties against the spool and spacer glands for when the fluid media is less than optimal.

Series 7 Solenoid and Air-Pilot Operated Valves
Series 7 Solenoid and Air-Pilot Operated Valves

(VDMA 24563)
ISO 15407-1, Size 26mm (size 01) and 18mm (size 02)
Side outlet manifold, Manifold assembly (non-plug-in)

The Series 7 electropneumatically and pneumatically operated valves have been designed to comply with ISO 15407-1 (VDMA 24563) standards size 26mm (VDMA 01) and size 18mm (VDMA 02).
The electropneumatically operated valves have the following types of operation available:

  • Air-Pilot, and air-spring return
  • Air-Pilot operation and return
Series 9 Air-Pilot Operated Valves
Series 9 Air-Pilot Operated Valves

Assembly with sub-base (ISO 5599/1 Standards) non-plug-in
Sizes 1, 2 and 3: 5-way/2-position; 5-way/3-position; single & double Air-Pilot valves


The Series 9 Air-Pilot operated valves have been manufactured in the sizes 1, 2 and 3, as recommended by the ISO Standards. Three different types of sub-base are available:

  • single sub-base with side ports
  • single sub-base with rear ports
  • manifold sub-base with common exhausts

complete with end blocks.
The Series 9 solenoid valves are also constructed so
as to be actuated in different ways:

  • Air-Pilot and spring return
  • Air-Pilot and return
  • Air-Pilot and differential
  • Air-Pilot return (bias override)
Series NA Valves (NAMUR Interface)
Series NA Valves (NAMUR Interface)

Air-Pilot operated 1/4” NPTF
3-way/2-position; 5-way/2-position; and 5-way/3-position valves
with Interface according NAMUR Standard


The valves Series NA are available in versions: 5-way/2-position and 3-way/2 position, Normally Closed or Normally Open. These are indirectly actuated valves and are available in single and double air pilot versions. The valve has a NAMUR interface pattern and can therefore be directly mounted on other suitable components that also have this hole pattern, such as certain rotary actuators ball valves or process valves. The single air pilot version is equipped with a mechanical return spring.
