Emerson‘s ASCO™ Series 327C Direct Acting Solenoid Valve – Precision, Efficiency, and Reliability
The ASCO™ Series 327C Direct Acting Solenoid Valve is a high-performance 3/2-way solenoid valve designed to operate with zero minimum pressure, making it an optimal choice for demanding industrial applications. This advanced solenoid valve is engineered with a balanced poppet construction, enabling high flow capacity while minimizing power consumption. It is widely used in power plants, refineries, and chemical processing facilities, where efficiency and reliability are critical.
The ASCO™ Series 327C Direct Acting Solenoid Valve features PTFE rider rings and graphite-filled seals, significantly reducing friction and preventing sticking. These elements extend the service life of the valve, ensuring consistent and long-lasting performance. The non-breathing design, along with Emerson’s advanced sealing technology, makes it an excellent solution for harsh environments, including hazardous areas and applications requiring extended dormancy.
