Pneumatic Valves
Pneumatics
Pneumatic valves are the core switching elements in every fluid power system - controlling flow paths from 2/2-way to 5/3-way configurations, operating at working pressures typically ranging from 0 to 10 bar, with flow rates (Cv/Kv) spanning 0.1 to over 5.0 m³/h depending on valve size and body design. Solenoid response times of 5-30 ms (direct-acting) and pilot-operated designs for up to DN50 port sizes make these components critical for cycle times in automated production lines. Key standards governing selection and installation include ISO 5599-1 (directional control valves), ISO 4401, and NAMUR NE 24/NE 44 for intrinsically safe environments.
As a specialist distributor for industrial pneumatics, fluidics-equipment.com stocks 3,090 pneumatic valve products across 17 subcategories - covering solenoid valves, ISO-standard directional valves, valve islands, check valves, throttle valves, stainless steel variants, and NAMUR-interface types from leading brands including Airtec and YPC. All products are sourced to comply with applicable ISO, DIN EN, and ATEX requirements for industrial and process automation.
