The ASCO Series 327 3/2-way solenoid valve is a direct-acting, high-reliability valve engineered for precise control of air, gas, and light fluid systems. Designed to operate with zero minimum pressure, it delivers dependable switching performance even in low-pressure or vacuum conditions.
Its balanced poppet design enables strong flow performance while minimizing energy consumption, making it ideal for both standard and mission-critical applications.
Built for durability, the valve incorporates advanced sealing materials that reduce friction and prevent sticking, ensuring long service life and consistent operation in demanding environments.
Best suited for:
- Process valve piloting
- Industrial automation systems
- Oil & gas and chemical processing
- Power generation facilities
