Asco Numatics has introduced the (WS)LPKF low-power pilot with Ex d certification for the compact 551-, 552- and 553-series pilot valves.

The valve is available with either an aluminium or stainless-steel enclosure and with a power consumption of 0.5W at 24VDC.

It has a low consumption and is intended for the process industry.

The low-wattage coil reduces battery drain and heat rise, minimises wiring costs and provides energy savings.

The savings in power usage over the installed life of the solenoid valve lower the total cost of ownership.

Compatible with the Asco Numatics 551-553 ranges in aluminium, brass (551 range only) and stainless steel, the valves have a large flow range of up to 860 litres per minute for the 551 valve and 3,800 litres per minute for the 553 valve.

Certified according to ATEX, IEC Ex and FM, the new range is suitable for applications in the offshore market, where high levels of safety and superior resistance to aggressive operating environments are required.

The housing and cover of the enclosure are in 316L stainless steel or painted aluminium and the operator can be rotated 360 degrees to select the best position for cable entry.

Electrical connection is via a shielded or unshielded cable gland (1/2 NPT) to access screw terminals.

The enclosure is supplied with a plastic exhaust protector fitted as standard and a metal exhaust protector is available as an option.

The operators are suitable for use in ambient temperatures from -40C to +60C and the flameproof enclosure is rated to 112GEx d IIB + H2 T6, 112DEx tD A21 IP67 T85C, Certification: IEC Ex, ISA and EN 60079-1, 61241-1.
