Rotork Australia solenoid valve range

Rotork Australia’s Fluid System division has available the Bifold Group range of direct mount solenoid valves, manifold and accessories for general valve actuator applications. These valves are available in 3/2 or 5/2 5/3 port configurations.

Compact in design, the solenoid valves feature a NAMUR mounting pattern, according to VDI/VDE 3845, that is designed to mount to any NAMUR valve actuator. This may reduce actuator response times, space requirements and also negate the need for a back plate. Rotork claims that installation costs are lower as the need for tubing fittings, brackets and assembly labour are reduced. All mounting screws and seals are included with the valve.

The solenoid valves have a mounting/spacer block which is free to rotate through 360°. This feature prevents the solenoid housing from coming into contact with the switch box and ensures the filter regulator remains upright.

The range also includes the manifold option which incorporates the NAMUR interface kit, based on the AXIS system, allowing the direct mounting of, for example, filter regulators and check, flow control, pressure relief and manual valves.

Rotork claims the system will accommodate all valve actuators in any orientation, resulting in no restrictions. The multifunction rotating system includes: inlet/exhaust flow control valve, high flow quick exhaust valve and optional fully rotational filter regulator.

The robust design is manufactured from 316 L stainless steel with an operating temperature range of -60 to 180°C, complies with worldwide approvals Ex d, Ex ia, Ex emb and is explosion-proof. A wide range of override options is available including auto reset, spring return manual override, stayput manual override, manual reset, tamperproof manual latch and latch energised.

The solenoid valve assemblies have SIL 3 third party certification to IEC 61508.
