Yamada^® EX-Air Solenoid Valves

Yamada EX-Air Solenoid Valves are electrically actuated shuttle valves designed for precise control of Air-Operated Double Diaphragm (AODD) pumps. Unlike standard c-spool valves piloted by an air signal, EX-Air valves operate via electrical input, allowing for accurate metering, batch control, and integration with automation systems.

Technical Specifications

• Pump Compatibility: Available on all Yamada pumps
  
• Mounting Options:
• Direct mount: Solenoid kit replaces standard air valve assembly on the pump
• Remote mount: Solenoid located separately; recommended for hazardous or explosion-proof environments
• Configurations: Single or dual solenoid versions
• Electrical Ratings: 12 VDC, 24 VDC, or 115 VAC
• Control Interfaces:
• Yamada YSC-3 controller (standard: 12 VDC single solenoid)
• Compatible with PLC (Programmable Logic Controllers)
• Electrical Connections: DIN
• Retrofit Capability: Kits can be installed in the field by replacing the air valve assembly

Functional Advantages

• Provides consistent pump cycle rate for batching or continuous flow
• Remote mount option improves safety in hazardous locations
• Simplifies preventive maintenance when paired with a controller
• Field retrofittable to existing pumps without major modifications
