Aira Euro Automation is a heavyweight in the valve industry, and their ISD Model Solenoid Valve is a flagship choice for industrial automation. It is a high-performance, internal-pilot operated valve designed primarily for handling air, water, oil, and inert gases.
Key Technical Specifications
The ISD series is celebrated for its balance of durability and precision. Here is a breakdown of what makes it tick:
Design: 2/2 Way (2 ports, 2 positions) normally closed.
Body Material: Typically forged brass or investment cast stainless steel (CF8/CF8M).
Pressure Range: Operates efficiently between 0.5 bar to 10 bar (depending on the specific orifice size).
Media Temperature: Capable of handling fluids ranging from -5°C to 80°C (with standard seals) or higher with specialized Viton or EPDM internals.
Performance Features
The "ISD" model stands out due to its Diaphragm-style construction. Unlike direct-acting valves, the internal pilot uses the pressure of the fluid itself to assist in opening and closing the valve. This allows the ISD model to control high-flow rates with relatively low power consumption.
Quick Response: Features a millisecond switching time, essential for precise dosing or safety shut-offs.
Reliability: The forged body ensures it can withstand high-pressure spikes without deformation.
Versatility: Available in sizes ranging from 1/2" to 2" BSP/NPT, making it adaptable for small-scale labs or large-scale manufacturing plants.
Common Applications
You will find Aira ISD valves in environments where "set it and forget it" reliability is mandatory:
Water Treatment: Controlling flow in RO plants and filtration systems.
Textile Industry: Managing steam and liquid flow in dyeing machines.
Pneumatics: Actuating air cylinders and massive air-line distribution.
HVAC Systems: Regulating chilled water or condenser lines.
Maintenance & Safety
To ensure longevity, it is recommended to install a Y-strainer upstream. Since the ISD model is pilot-operated, small debris can clog the pilot orifice, causing the valve to stick.
