Valves with Integral Position Sensing

Product Announcement from HydraForce, Inc.

Valves with Integral Position Sensing-Image

HydraForce has released valves with an integral sensing option capable of transmitting an on or off signal. These valves are designed with parts commonality in mind which allows these sensing options to be easily applied to numerous valves, and keeps the sensing option cost-effective. This new sensing solution was designed for interchangeable use with any existing HydraForce cartridge valve, is compatible with manual override options, and uses an industry standard cavity.

Smart hydraulic valves are a sensible choice for the following applications where position-sensing is important:

¨ Lifting

¨ Lowering

¨ Machine State (On, Off)

¨ Steering Modes

¨ Safety Modes with Manual Override

The innovative sensing option design consists of assembling a common solenoid valve pole tube and hydraulic valve assembly on the opposite ends of a coupling tube, which contains an elongated plunger. The new coupling tube, sensor and sensor housing are designed such that they are usable in valves of different types and sizes ranging from 10 to 16 sizes. These new components are connected to Hall Effect sensor element which monitors and transmits the appropriate voltage signal when the valve is actuated or in the neutral position. The sensing element chosen was a Hall Effect sensor which is known for its proven reliability in the field.

An additional benefit of the coupling tube containing the sensing element is that this enables the use of a manual override. This is an option that had previously not been available in an integral sensing valve. Poppet style valves incorporate a special poppet with elongated hydraulic overlap during transition; this ensures faulty detection does not occur in the case of leakage. Both Deutsch and M-12 connection options are available for connecting the sensing element into your wiring harness, allowing for easy system integration in both industrial and mobile applications.

Among the many uses for this sensing solution are monitoring of lifting and lowering functions, machine state, multiple steering modes, and to enable dual redundancy operation of hydraulic press and other industrial equipment.

These sensing options were designed with manufacturers laboring to meet the following specifications; 2006/42/EC: Machinery CE Marking, EN693:2001 Machine Tools, Safety Hydraulic Presses, EN12622: Safety of Machine Tools, Hydraulic Press Brakes, ISO13849: Safety of machinery -- Safety-related parts of control systems (part of the EN15000 spec). The items we supply are components and do not have a complete function of their own, and are to be fitted by our customers to their products, in accordance with the EC, EN, or ISO Directives. We have tested and passed all EMI and RFI and EMC tests which are intended to give assurance that the products supplied by us are, in isolation, capable of passing EMC tests required to CE rate the sensor.

However, it must be emphasized that when components and assemblies are fitted with their respective control equipment and wiring, the Electromagnetic Emission Signature as a whole will potentially be significantly changed and must therefore be subject to the customers own EMC tests and overall safety assessments in accordance with the relevant directive(s).
