21H7KB120

ODE 21H7KB120 is a 21H Series, 2/2-way Normally Closed (NC), pilot-operated (indirect/combined acting) solenoid valve designed for water, air, and inert gases

ODE 21H7KB120 is a 21H Series, 2/2-way Normally Closed (NC), pilot-operated (indirect/combined acting) solenoid valve designed for water, air, and inert gases. It features a brass body, NBR seal, and a large 12 mm orifice for high flow capacity.

Operating Principle

Unlike the 21A direct-acting valves you asked about earlier, the 21H7KB120 is a pilot-operated valve:

• Power OFF: Valve stays closed.
• Power ON: Pilot system opens the main valve.
• Requires minimum 0.1 bar pressure differential to operate correctly.

Fluid Compatibility

The NBR-sealed version is recommended for:

• Water
• Air
• Inert gases
• General industrial fluids compatible with NBR

Operating temperature for NBR seals is −10°C to +90°C.

Typical Applications

• Water treatment plants
• Industrial automation
• Industrial washing equipment
• Packaging machinery
• Thermoregulation systems
• Car wash systems
• Air handling systems
