The H43 Series BASO valve is a combination A valve, B valve, and automatic pilot valve. A manual valve handle with On, Off, and Pilot positions allows operation of the valve without a thermostat. Application include room heaters, wall furnaces, and commercial cooking.
The H43 valve contains a plug valve with multiple drillings, which allows it to serve as both the main burner valve and pilot valve. The valve handle indicates the operating position. Safe lighting is accomplished by a positive interlock between the valve handle and reset button, which allows for resetting the valve to the pilot position only. The handle incorporates a lock button to prevent accidentally turning off the valve. The lock button must be lifted to permit turning the plug valve to the Off position. The main burner may be throttled between the On and Pilot position through the use of the handle.
- Compact Permits installation in dimensionally-restricted applications
- Safe Lighting Interlock Allows gas flow only to the pilot at the time of lighting
- Shutoff Lock Requires pull button to be lifted and turned to Off position, preventing inadvertent shutoff of the pilot
H43 valves may be mounted in any convenient position with the reset button and manual valve handle accessible.
