Mini-solenoid valves claim lower consumption

Asco Numatics product story

Asco Joucomatic has extended the range of operation for its 302 Series of mini-solenoid valves, with new 2/2 (NC-NO) and 3/2 (NO-U (universal) and universal vacuum) versions.
Asco Joucomatic has extended the range of operation for its 302 Series of mini-solenoid valves, with new 2/2 (NC-NO) and 3/2 (NO-U (universal) and universal vacuum) versions.
In common with existing valves in the 302 series, the new additions offer the lowest energy consumption on the market: just 0.5W for a flow rate of 11 litre/min.
They are designed for use in the medical, automation packaging and process control sectors.
The new 15mm valves offer OEMs and users a mini-shutoff facility (2/2 NO-NC), and also the flexibility of universal (ie pressure at any port) operation on air or neutral gases or vacuum.
Rated for operation at 0.5, 1 or 2W, they offer excellent life, at 100 million cycles, and benefit from IP65 or IP67 protection for high integrity operation in aggressive environments.
In addition, the option of an intrinsically safe "ia" version is available for use in areas (0-20 II 1GD) where combustible gas/dust pose a continuous danger.
The 302 Series incorporates an IXEF body and PET spool designed as a monobloc assembly, which guarantees no rotation of the valve spool.
This combination ensures that the 302 is a robust unit with a long service life.
The valves suitability for automation use is also enhanced by a "lighter- than-light" specification, including integrated LEDs and electrical protection, which facilitates integration directly into equipment and machines and also into robotic systems.
The 302 Series design with its CNOMO mounting to standard E06.36.120N offers users the flexibility of several operating configurations: mounted on a subbase for direct control of small-diameter cylinders, fast and simple pneumatic connection is assured - whether single or multiple valves are employed - by a new modular aluminium base; mounted on Asco Joucomatic Series 304 electropneumatic interfaces for flow rates of up to 154 litre/min; integrated directly into remote valve actuators (with a maximum volume of 50cm3) for piloting operations or controlling pressure-operating valves; or combined with an Asco Joucomatic manifold, whether standardised or not.
All these operating configurations benefit from the facility for two methods of pneumatic connection: a CNOMO pneumatic interface - on the same side or opposite side to electrical connections (M12 or flying leads).
Depending on the requirements of each specific application, the user can choose the appropriate electrical connection (DIN, ISO, M12 or flying leads) and level of protection - the 302 is the only mini-solenoid valve on the market offering IP67 protection for perfectly safe operation in aggressive environments.
For more general applications, an IP65 rated version is also available.
