Modular valves ease installation
The IsysNet system is based on a modular construction, using robust quick-fit latching mechanisms that enable valve, I/O and communication modules to be installed on common manifold units in seconds.
Parker Hannifin has released pneumatic valves that meet ISO standard 15047 parts 1 and 2 (ISO sizes 02, 01, 1, 2 and 3) The IsysNet valves combine exceptional pneumatics performance, with 20% less power consumption and far lower breakaway forces, with integrated and fast serial bus communications that enable valves to be installed quickly and easily in a wide range of industrial applications

New series of Schrader pneumatic couplings
Parker Pneumatic has further extended its industry standard Schrader Range of quick acting pneumatic couplers with the introduction of the Euro Series.
The IsysNet system is based on a modular construction, using robust quick-fit latching mechanisms that enable valve, I/O and communication modules to be installed on common manifold units in seconds and without the need for extra connector plates that are typically required with other ISO valves.
In addition, modules can be reconfigured on site, while serial modules can be changed even when the system is powered up and without affecting the controlling software.
I/O modules are also colour-coded for quick identification.
The serial modules use a fast backplane with the latest change of state (COS) connections for optimum performance and allow an IsysNet manifold unit to be linked directly to sensors, limit switches and encoders and to remotely operated solenoid valves or other pneumatic devices.
The IsysNet system provides a choice of digital, analogue and high-wattage I/O, with individual modules incorporating comprehensive safety features such as short circuit and open circuit detection.
The system can be extended considerably using communication modules, which support up to 62 I/O modules and up to 252 inputs and 252 outputs.
Both electronic and pneumatic connections are built into a single manifold-mounted end plate.
Mechanically, the new IsysNet valve modules are compact, with a low profile and are available as single or double-solenoid modules, with internal or external pilots, Cv ratings of 0.6 to 6.0 and a choice of NPT or BSpp G standard ports.
Perhaps as importantly, the solenoid valves use up to 20% less power than conventional ISO devices of the same size, while the spool seals have a far lower breakaway force.
In addition, the spool seals feature a wear compensation system, with the land area of each seal designed so that it is constantly forced outwards to eliminate the effects of wear, providing in excess of 90 million cycle life.
The new IsysNet valves are CE marked and CSA/C-US approved, with NEMA 4 and IP65 certification. Request a free brochure from Parker Hannifin ...
