HYDRAULICS & PNEUMATICS PRODUCTS COMPACT SOLENOID GAS VALVES
A new range of compact solenoid gas valves which comprises four valves featuring units designed for high pressure cut-off, safety shut-off, proportional flow control and purge/drain applications, have been launched by Magnet Schulz. The pressure cut-off valve offers input
pressure capability of up to 1050bar. This features an internal design that balances the pressure around a primary sealed tube, housing the valve that the hydrogen runs through. The pressurised gas is bled either side
of the spool, allowing the spool to move freely under magnetic control from the separate electric coil due to a negligible pressure differential. The body size of the 1050 bar high pressure cut-off valve is just 32mm in diameter. The new range includes intrinsically safe explosion-proof variants of the
cut-off, safety shut-off and proportional flow control valves, specifically to address static gas-powered fuel cell system applications where ATEX/IECEx certification is mandated. The range is also suitable for compressed natural gas (CNG) fuel installations and other gas applications. Mobile and portable applications, including vehicles governed by
the EC79/2009 type approval of hydrogen-powered motor vehicles regulation, do not require this certification. Here, thanks to their compact sizes, applications in automotive fuel cell developments are a core target sector, the company explains.

Valve islands offer the ability to connect multiple solenoid valves, each with their own individual coils, together in one component. Streamlined design offers space savings, whilst lower installation costs are achieved since there is no need to wire each individual valve. A reduction in visible wiring also achieves a more aesthetic and compact finish, plus reduced energy usage. Camozzi Automation’s extensive
UK stock of HN and F Series components gives it the ability to assemble and dispatch bespoke multipole valve islands with maximum speed, meaning that from specification to
delivery can often be
undertaken in as little as 24 hours. Of further benefit, customers also have the option to configure their own valve islands using Camozzi’s online configurator.

MAGNET DRIVEN GEAR PUMPS OFFER HIGH PUMPING PERFORMANCE
Michael Smith Engineer’s Micropump range of magnet driven gear pumps has been extended to include new options which provide exceptional pumping performance for high system pressure applications. The GLH Series of compact, magnetically driven,
external gear pumps are designed for fluids handling applications with system pressures up to
103bar (1500psi) and maximum differential pressures to 8.5bar. They can deliver flows from 2l/min up to 22l/min (at 2850rpm) on liquids with a maximum viscosity range up to 2500cp, at temperatures up to 121˚C. Providing rugged, reliable and leak-free performance for any high-precision pumping application, these compact units can be incorporated into the design of high-precision fluids handling systems. The GLH Series can be coupled with multiple drive and motor
options while a choice of configurations means they can meet the most challenging applications, the company adds.
