Solenoid pilots are used with other pilots for overrides in
domestic hot water or safety applications. The “Normally
Closed” Solenoid pilots are designed to shut down the
Main valve if there is a power failure. “Normally Open”
Solenoid pilots are designed for heating, or other
applications where overheating will not be harmful, since
they remain open during a power failure.
• Remote control
• Emergency shut-down feature
• Automatic start-up and shut-down capability (timer required)
• More economical to use than electric shut-off valves
• Operating modes
– Normally Open
– Normally Closed
• 120 volt electrical service required
• Maximum operating pressure 250 psig (17.3 bar)
Do not use “Normally Open” Solenoid
pilots for direct temperature control in
domestic water applications.
Failure to follow this warning can cause
serious burns, personal injury, or death.
