Pneumatic valves

Directional and flow control of compressed air in industrial control and automation circuits.

Product Overview

Pneumatic valves control the direction and flow of compressed air in industrial control and automation circuits. Tose'e Tejarat Sayyalat supplies manual (lever) valves, solenoid (electrically operated) valves and emergency stop valves for equipping pneumatic control panels.

Applications

  • Control circuits for industrial pneumatic equipment
  • Production line emergency stop systems
  • Control of pneumatic cylinders and actuators

End-User Industries

Industrial automationPetrochemicalSteelProduction lines
Manual, solenoid and emergency pneumatic valves

Technical Specification

Actuation typeManual (lever), solenoid (electrical) or emergency
Common electrical control voltage24 V DC or 220 V AC, according to the project specification
Typical working pressureGenerally up to around 10–16 bar (depending on valve type and application)
ConnectionThreaded (commonly BSP/NPT) or push-to-connect, to match the project's pneumatic pipework standard
Sub-base mounting standard (industrial valves)To ISO 5599-1 in sizes D1 (42 mm wide), D2 (52 mm wide) and D3 (65 mm wide)
Solenoid interface (NAMUR)The standard NAMUR interface for mounting solenoids on pneumatic actuators
Source: The pressure, voltage and mounting standard values above follow common industry standards for pneumatic valves (including ISO 5599-1) and are comparable with the catalogues of established international brands such as Festo, SMC and Parker. Exact figures depend on the valve type, the manufacturer and the project requirement.

In plain terms: An emergency stop valve should always be a mechanically latching type rather than purely electrical, because the circuit must still be able to be cut manually and immediately if the power supply fails. This is a point HSE safety inspections at large industrial plants usually check specifically.
