Pneumatic fittings, tubing and valves
Push-to-connect fittings, compressed air tubing and control valves for industrial pneumatic control circuits.
Category Overview
This category covers three complementary product groups for equipping industrial pneumatic control circuits: push-to-connect pneumatic fittings, PU pneumatic tubing to carry compressed air between circuit components, and control valves (manual, solenoid and emergency). Tose'e Tejarat Sayyalat supplies all three together so that a pneumatic control panel can be equipped completely.
A pneumatic control circuit is the part of an industrial automation system that uses compressed air (typically 6 to 10 bar) to command the valves, cylinders and pneumatic actuators on a production line. Designing it correctly requires dimensional compatibility between three main elements: the diameter and pressure grade of the tubing, the size and standard of the quick fitting, and the valve mounting interface (sub-base or NAMUR) on the actuator. A mismatch in any of the three causes pressure loss or leakage in the circuit.
Industry reference — international standards for pneumatic control circuits
The table below lists the international reference standards for each element of a pneumatic control circuit. These standards also underpin the technical catalogues of established international brands such as Parker (Legris/Prestolok series), Festo and SMC.
| Circuit element | Reference standard | Application |
|---|---|---|
| Push-in pneumatic fittings | ISO 6150 (thread) and the common push-to-connect design | Tool-free connection of tubing to circuit components |
| Pneumatic tubing (PU) | Common metric sizes (such as 4×6, 6×8, 8×10 mm) | Carrying compressed air between control circuit components |
| Industrial sub-base valve | ISO 5599-1 (sizes D1, D2, D3) | Mounting directional control valves on a manifold |
| Solenoid mounting interface on the actuator | VDI/VDE 3845 (NAMUR interface) plus ISO 5211 (mechanical shaft connection) | Mounting solenoids and limit switches on rotary actuators |
