Maxon 150SMA11AA11BB22A0 Gas Valve
The Maxon 150SMA11AA11BB22A0 Gas Valve is a 1 1/2" ANSI threaded, normally closed electromechanical safety shut-off valve designed for high-demand industrial burner systems. Part of the 5000 Series, this automatic gas shut off valve features a rugged cast iron body and a NEMA 4 enclosure rating, making it suitable for general-purpose natural gas service in diverse environmental conditions. It operates on a 115VAC 60Hz solenoid and motor voltage, utilizing a 6-second motor timing for reliable safety shut-off valve cycles. This model is equipped with the VOS2/VCS2 switch options, providing dual Proof-of-Open and Proof-of-Closure verification for maximum system safety. With a Standard Port flow capacity and internal trim package 1 (400 series stainless steel seat and hardened ductile iron disc), it handles a maximum operating pressure differential of up to 70 PSIG. The inclusion of Buna body O-rings and bumper ensures a positive seal for natural gas applications, maintaining compliance with ANSI standards for terminal gas train components.
Key Benefits for Contactors:- Enhanced System Monitoring: Integrated VOS2 (Valve Open Switch) and VCS2 (Valve Closed Switch) provide definitive signal feedback to the flame safeguard or PLC.
- Durable Sealing: Features a 400 series stainless steel seat and PEEK follower ring within the trim package for high-cycle reliability and minimal leak rates.
- Standardized Flow: The 1 1/2" DN40 standard port design offers a Cv of 53, optimizing pressure drop across the gas train.
- Environmental Protection: NEMA 4 cast iron construction protects internal electromechanical components against dust and moisture in mechanical rooms.
- Automatic Reset: The auto-reset motor eliminates the need for manual intervention after power restoration or safety limit clears.
What is the difference between the 150SMA11AA11BB22A0 and manual reset models?
This specific model is a 115V automatic reset version, meaning it re-opens upon signal command after a safety shutdown, whereas manual reset models require a physical lever pull to restart the gas flow.
Can this valve be used for propane or other fuel gases?
While designed primarily for natural gas service with BUNA N seals, compatibility with other gases depends on the specific chemical composition and pressure requirements; verify with 400 stainless steel and cast iron material compatibility charts.
Is the VOS2/VCS2 switch package field-replaceable?
The VOS2/VCS2 switches are integrated into the actuator assembly; for maintenance, ensure the proof-of-closure (VCS2) is correctly wired to the interlock circuit for proper burner startup sequencing.
