NFPA D03 (SWH-G02)

FEATURES

• Armature operates in oil system. Impact is cushioned, noise is reduced and solenoid life is increased.
• Wet armature solenoid eliminates pushpin seal, therefore no seal wear or leakage for longer valve life.
• Molded coils for maximum insulating properties, which is impervious to moisture and dirt.
• Plug-in solenoid, for ease of maintenance.
• All spools and bodies are interchangeable, simplifying maintenance.
• Indicating signal lights and bolt kits are standard.
• High pressure, high flow rating, and low-pressure drop.
• Specially designed, balanced spool allows proper shifting force, for maximum reliability and long life.
• Viton seal kits are available for fire-resistance fluids.
