2/2 Way Solenoid Valve 1″ SST | 24V DC Normally Closed

The 2/2-Way Stainless-Steel Solenoid Valve provides dependable electrical on-and-off control for water, air, and compatible neutral fluids. This industrial valve combines a 1-inch DN25 connection size, corrosion-resistant stainless-steel construction, a 24V DC coil, and normally closed operation.

Its direct-acting mechanism is designed to operate without minimum inlet pressure, making the valve suitable for compatible zero-pressure, gravity-fed, low-pressure, and conventional pressurized systems.

When the solenoid coil is de-energized, the valve remains closed to stop fluid flow. Applying the specified 24V DC power energizes the coil and opens the valve. This fail-closed function supports automated shutoff, equipment protection, tank filling, system isolation, and process-control applications.

The low-voltage DC coil can be integrated into a properly engineered system using a compatible DC power supply, relay, timer, level switch, pressure switch, leak-detection device, control panel, or programmable controller.

Its stainless-steel construction provides strength and corrosion resistance for approved commercial and industrial applications. Potential uses include reverse osmosis equipment, deionization systems, industrial water filtration, process-water assemblies, irrigation equipment, compressed-air systems, and OEM machinery.

Confirm the coil polarity, voltage tolerance, current draw, maximum pressure, temperature range, thread standard, stainless-steel grade, enclosure rating, and fluid compatibility before installation.

Technical Specification

Key Features

• 2/2 way normally closed (NC) operation
• Direct acting design (no minimum pressure required)
• 1″ DN25 connection size for high-flow applications
• Stainless-Steel valve body for corrosion resistance
• 24V DC solenoid coil
• Fast response and reliable sealing
• Suitable for continuous duty cycles
• Compact, serviceable industrial design

Applications

A 2/2 way normally closed (NC) stainless-steel solenoid valve is designed to remain closed when de-energized and open only when power is applied. This makes it ideal for applications requiring fail-safe shutoff, controlled flow, and reliable on/off operation.
