BASO H91RA-4C REVB Gas Valve

The BASO H91RA-4C REVB Gas Valve is a heavy-duty, electrically operated shut-off valve designed for high-demand HVACR and industrial gas-fired applications. Engineered for precision, this 2-wire automatic gas valve utilizes a bipolar magnetic operator to provide reliable on/off control for natural gas and LP systems. With a 3/4" NPT inlet/outlet and a 120V AC 60Hz coil, it supports a flow capacity of 310 CFH at a 1/2 PSI pressure drop. This unit serves as the direct replacement for H91RA-4 and H91RA-1 models, ensuring a seamless fit during field service. The rugged aluminum body and UL-listed steel cover with a conduit hub make it ideal for boilers, commercial cooking equipment, and industrial heaters. Its normally closed configuration and 1/8-27 NPT pilot taps allow for integrated pilot gas flow, maintaining safety and performance standards essential for professional contractors.

Common Questions

What is the maximum operating pressure for the H91RA-4C?
This valve is rated for a maximum pressure of 0.5 PSI (35 mbar), making it standard for low-pressure gas-fired appliances.

Can the H91RA-4C REVB be mounted in any orientation?
For optimal performance, it should be mounted on a horizontal manifold with the magnetic operator in the upright position, though it can be tilted up to 90 degrees from vertical.

Is this valve suitable for high-voltage industrial systems?
Yes, this specific model is designed for 120V AC electrical demand signals from thermostats or controllers.
