331 Series 15mm Miniature Solenoid Valve – Complete Guide To 3/2 Way Direct Acting Pneumatic Valves 2026-09-09
This guide provides an overview of the WAALPC 331 Series 15mm miniature solenoid valves, a family of 3/2-way direct acting pneumatic valves for space-constrained applications. Available in Normally Closed (NC) and Normally Open (NO) configurations, the series features a compact 15mm width, orifice sizes from 1.0mm to 2.0mm, operating pressure up to 10 bar (1.0 MPa), and fast response times (open <10ms, close <12ms). The guide covers ordering code structure, technical specifications, direct acting working principle, and key features including multiple socket connection types, voltage options (DC6V, DC12V, DC24V, AC24V), circuit board options, and power consumption from 2.5W down to 0.5W. Applications span textile machinery, medical devices, electronics manufacturing, and industrial automation. This guide serves as a practical reference for engineers and procurement specialists selecting miniature solenoid valves for compact pneumatic systems.
