2W Series 2-Way Direct Acting Zero Differential Solenoid Valve – Brass & SS304

Product Overview
The 2W Series is a high-performance, two-position two-way solenoid valve featuring a direct-acting or semi-direct-acting lifting diaphragm structure. This design allows for “Zero Differential” activation, ensuring the valve opens and closes reliably even at 0.0 MPa (0 PSI), making it the ideal solution for systems with inconsistent or minimal pressure, such as gravity-fed tanks and low-pressure pipelines.
