2W31 Series Direct Lift Diaphragm Solenoid Valve for Industrial Automation
DELCO's 2W31 Series Solenoid Valve features a direct lifting diaphragm structure, enabling it to function reliably from zero pressure, making it ideal for low-pressure systems. It is versatile, capable of controlling media such as air, gas, water, and oil. The design ensures consistent, leak-tight sealing to enhance product lifespan and overall reliability in various industrial applications.
Features
Zero Pressure Start and Wide Media Compatibility
✅ Direct Lifting Mechanism (Zero Pressure Start): The direct lifting (Direct Acting) design allows the valve to operate without the need for differential pressure, permitting reliable operation even at 0 MPa (zero pressure), which expands its suitability to low-pressure and gravity-fed systems.
✅ Enhanced Sealing with Diaphragm Structure: Utilizes a diaphragm structure to ensure consistent sealing performance, contributing to a longer product lifespan and high leak-tightness for reliable control.
✅ Broad Media Application: Suitable for controlling a variety of common fluid media, including Air, gas, water, and oil.
✅ Versatile Temperature and Pressure Ratings: Designed for a maximum working pressure of 1.0 MPa. Offers multiple sealing options for temperature ranges: NBR for up to 80℃, EPDM for up to 100℃, and VITON for up to 120℃.
✅ Flexible Power and Connection Options: Supports a wide range of voltages (DC 12V, 24V; AC 24V, 120V, 240V/60Hz, 110V, 220V/50Hz) and features connection sizes from 3/8'' to 2'' with thread (BSPP/NPT/BSPT/NPT) or flange options.
