Maxon 57371 Valve Position Switch Assembly for 3-6 Inch GP VCS1/VOS1

The Maxon 57371 is an open/close switch assembly designed to provide positive valve position feedback for large-frame Maxon safety shutoff valves. Engineered for use with 3-inch through 6-inch general purpose (GP) VCS1/VOS1 valve models, this switch assembly delivers discrete "valve open" and "valve closed" signals essential for burner management systems and flame safeguard controls.

Key Features:

• Provides independent valve open and valve closed position feedback for safety interlocks
• Compatible with 3-inch to 6-inch GP VCS1/VOS1 valve bodies and actuators
• Mounts directly to valve actuator with robust cam mechanism for position tracking
• Dry contact outputs integrate with PLCs, flame safeguards, and safety relays
• Enables code-compliant proof-of-closure (POC) and open-position interlocks
• Industrial housing with repeatable trip points for reliable combustion applications

This switch assembly is a critical component in industrial and commercial combustion systems, supporting start-permissive logic, emergency shutdowns, and maintenance diagnostics. The precision-engineered design ensures accurate valve position monitoring in demanding environments where reliable fuel control is essential for safety and operational compliance.
