Pneumatic Valves for metering and outlet valves

In automated lubrication and dispensing technology, pneumatic valves form the control-technical basis for activating media units. These valves regulate the flow of control air to open or close dispensing or outlet valves within milliseconds. The exact switching characteristic is crucial for the repeatability of dispensing cycles and the definition of clean break-off edges at the application point. ABNOX pneumatic valves are designed for high switching frequencies and a long service life in industrial continuous operation.

Pneumatically actuated dispensing components require a stable and fast-responding control signal. Delays in the pneumatic circuit lead directly to fluctuations in the amount of medium applied. The use of specialized pneumatic valves ensures that the piston stroke of the controlled valve occurs synchronously with the electrical signal from the PLC. This minimizes the risk of dripping or incomplete media application within the tribological chain.
 

Product Specification

Manufactured as directional control valves (e.g., 3/2- or 5/2-way), optimized for installation in control cabinets or directly on the actuator. The valves feature electromagnetic pilot controls with low power consumption and high thermal resistance. The internal design is engineered for high flow rates (kv value) with compact dimensions, enabling short switching times. Standardized push-in fittings for the pneumatic lines guarantee fast installation and a leak-free connection.

• High Switching Frequency: 
  The mechanical components are validated for millions of switching cycles without significant wear, which extends the maintenance intervals of the dispensing system.
• Minimal Switching Times: 
  Optimized flow paths within the valve housing ensure rapid pressure buildup at the actuator, resulting in a precise response from the dispensing device.
• Robust Housing Design: 
  The use of corrosion-resistant materials (e.g., anodized aluminum) provides resistance to industrial environmental influences and lubricated compressed air.
• Integrated Manual Override: 
  Enables manual functional tests during commissioning or maintenance without the need for electrical control.

The use of ABNOX pneumatic valves stabilizes the entire dispensing process through reliable time control. The exact separation between the pressurization and venting of the control chamber within the dispensing device prevents uncontrolled movement sequences. This leads to a significant reduction in reject rates and increases process speed in automated production lines. Consequently, these valves form the technological interface between electronic signal processing and mechanical media application.
