Product Guide

Manual pneumatic valve

A pneumatic valve or valve-assembly component for a specified control function. Port arrangement, switching states, actuation, control voltage where applicable and flow capacity define the selection; proportional control and on/off switching are different requirements.

Practical purchasing guidance for universities, research laboratories, industry and institutional buyers.

Applications and workflows

Typical workflows help you define the application and compare suitable product configurations.

  • Compressed-air control and pneumatic installation
  • Industrial automation, positioning and handling
  • Industrial switching, control and circuit protection

Technical selection criteria

Include these parameters in your inquiry to align laboratory users, technical teams and purchasing.

  • Valve function, number of ports and actuation method
  • Port size, thread standard and tubing connection
  • Working pressure, flow capacity and required air quality
  • Output signal, supply, protocol and response time
Variants and compatibility

Dimensions, tolerances, load class, material compound and connection standards may distinguish similar-looking parts. Use the original part number or a verified drawing whenever possible.

Documentation and delivery

A dimensional match alone is not a replacement approval. Verify load, duty cycle, material, medium and installation against the machine documentation. Request traceable part identification and the relevant technical drawing. Pressure-rated or safety-critical installations require their own suitability review.

Confirm the required documents, packaging and delivery conditions for the selected item and destination.
