Pneumatics specialist Airtec offers a wide range of electrically and pneumatically actuated cryogenic valves for reliable, fail-safe regulation and control tasks, even at double-digit sub-zero temperatures.
These include the robust, stainless steel piston spool valves from the ICK-09 and ICK-10 series with electric actuation and G 1/8 or G 1/4 connection. The IP65-rated units are ideal for harsh operating conditions, e.g. in shipbuilding and marine technology, chemical plant engineering, the animal feed and food industry or agricultural technology. They are available in 5/2-way and 5/3-way versions and are designed for a temperature range of -30 °C to +80 °C.
At a control and operating pressure of between 2.5 bar and 8 bar with filtered, oil-free and dried compressed air in accordance with ISO 8573-1:2010, flow rates of 810 Nl/min to 2100 Nl/min are achieved, depending on the device variant. AIRTEC's programme includes the modular base plate systems RF-09/n and RF-10/n for the construction of frost-resistant valve terminals, which can be configured with any number of stations with units of both valve sizes. Free valve stations can be sealed with appropriate sealing plates.
