Working Principle
The ASCO 327 / 8327 Solenoid Valve operates using an electromagnetic coil that actuates a plunger to open or close internal flow passages. Its 3/2-way configuration allows switching between two output ports, making it ideal for controlling single-acting actuators, pneumatic cylinders, or pilot valves.
The direct-acting mechanism ensures consistent operation regardless of system pressure.
Typical Applications
Pneumatic and automation systems
Oil and gas control systems
Power generation equipment
Chemical and process industries
Machine tools and packaging lines
Food and beverage automation
Valve actuation and air control panels
