SKU CH-RNDN-B1VKQ

Two-way normally open actuator controls flow direction in HVAC systems

  • 2-way normally open actuator controls flow direction
  • Legend Valve 800-710 model ensures reliable HVAC operation
  • Designed for RV heating and cooling systems
  • New condition guarantees full factory performance
  • California Proposition 65 warning for chemical awareness

Product Identity

The Legend Valve 800-710 is a 2-way normally open actuator designed for HVAC systems in recreational vehicles. It controls fluid flow by remaining open when de-energised, making it suitable for fail-safe heating or cooling circuits. Installers and RV owners use it to automate zone valves or isolation duties in hydronic and forced-air setups.

Operational Limits

The actuator operates in a normally open configuration, so power must be continuously applied to hold the valve closed. This behaviour defines the control logic and wiring requirements for any thermostat or building-management system. The component carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm, which may restrict its use in certain regulated environments.

Pre-Installation Checks

Verify that the control voltage and signal type match the actuator's coil specifications before wiring. Confirm the valve body port size and thread pattern align with the existing piping to avoid adapters. Ensure the mounting orientation and ambient temperature range suit the RV mechanical room layout.

Questions about this item

Which Legend Valve 800-710 version should I choose for a normally open requirement?

The 800-710 model is a 2-way normally open actuator, so it fits systems needing flow until energised.

What does the 2-way normally open design mean once installed in an RV heating system?

It allows fluid or air to pass by default and closes only when the actuator receives a signal.

How does the actuator interface with the valve body and what does that cap in practice?

It mounts directly to a compatible 2-way valve body and controls on-off flow without modulation.
