A compact directional pneumatic valve that can operate as two independent valves in a single body (or in conjunction with a manifold) is now available in 1/4in as well as 1/8in sizes.

A compact directional pneumatic valve that can operate as two independent valves in a single body (or in conjunction with a manifold) is now available in a new size. Originally launched by Hoerbiger-Origa in a 1/8in size, the S10 valve is now also available as a 1/4in valve. The S10 addresses user requirements for smaller valves and also incorporate many other advantages, as Hoerbiger-Origa's product manager, Jochen Krinn explained: 'In recent times, the volume market trend for pneumatic control valves has swung away from the universal standard designs (like ISO), as companies can gain a competitive advantage by using more compact, efficient and economic valve designs'.

'This is being achieved in the S10 by the adoption of new materials, better manufacturing, higher precision and optimised designs.' He said: 'The S10-1/8in is less than two-thirds the size of our equivalent standard S9 valve; yet offers a 30% increase in flow rate'.

'Its life expectancy is in excess of 25 million cycles, so can it be installed with confidence in continuous process plants where it may receive no maintenance for literally years.' Krinn enthused: 'And perhaps best of all they are up to 30% cheaper than previous models.' Hoerbiger-Origa offers the S10 in a wide range of options, variants and configurations.

All come with the option threaded ports or push-in connections, manual overrides are standard with electrically actuated versions.

There are 2x3/2, 5/2 an 5/3 way versions and a choice of mono-stable or bi-stable formats, all with nominal flow rates of 650 litre/min for 1/8in, 1100 litre/min for 1/4in, and nominal power of 1.1W.

Options include an LED indicator and external pilot air.

The simplicity of the Slop's mounting manifold design makes it compact yet able to provide a common air supply for up to 16 valves.

Several different valve functions to be combined on the same manifold, a feature with considerable cost saving potential for systems builders.

Innovations on the manifold include flow dividers and intermediate compressed air connection.

These can be set up such that one section will feed valves at one pressure and another section will supply other valves at a different pressure.

It is possible to supply maximum three different pressure zones.

This is simply achieved by setting the flow dividers at two selected points and plugging the additional pressure port in between , such that each port of the manifold can then be fed with different pressures.
