Pneumatic valves

Frequently asked questions — Directional Valves

• How to choose between a pneumatic valve and another component from the pneumatic family?

  The choice depends on the function required in your pneumatic circuit. Whereas the pneumatic components category encompasses various elements for air regulation or treatment, the valve is specifically designed to direct, stop or alter the direction of the compressed air flow to the actuators. The valve should be favoured whenever the directional control of a cylinder or a pneumatic motor is the main objective of the installation, in addition to the other components required for pressure management or filtration.
• What are the criteria for selecting the right series of valves?

  The selection of the series must be rigorously aligned with the technical requirements of your application, particularly in terms of flow rate, operating pressure and control mode. It is imperative to check the compatibility of the proposed series with your operating environment to ensure optimal sealing and a service life consistent with the technical specifications. Analysing the characteristics specific to each series is essential to avoid any sizing errors, as each range responds to distinct operational constraints inherent to its technical design.
• Should specific lubrication be provided for valves?

  The need for lubrication depends directly on the technical recommendations associated with the selected valve series. Some models are designed to operate without oil input in the compressed air flow, while others require constant lubrication to maintain the operation of seals and internal components. It is essential to consult the specifications of the chosen series to determine whether lubricated or non-lubricated air is required, in order to ensure the durability of the equipment and prevent premature wear of the components.
• What precautions should be taken for mounting and sealing?

  To ensure the sealing of the circuit, the assembly must comply with the recommendations relating to the types of connectors and the specific tightening torques for the valve series used. Particular attention must be paid to the installation environment, especially regarding the presence of impurities that could compromise the seals. Correct installation also involves checking the alignment of the pneumatic connections to prevent any mechanical stress on the valve body, which could alter its performance and reliability over the long term.
