HTS Maxon 8000 Series Pneumatic Shut Off Valve

The Honeywell Maxon Series 8000 Pneumatic Safety Shut-Off Valve provides reliable, automatic shut-off for fuel gas service. Designed for high-pressure applications, this air-actuated valve delivers tight sealing and rapid response times for safety-critical combustion systems. It is available in multiple body sizes and configurations to meet general-purpose or hazardous-area classifications.

Features & Benefits

• Pneumatically operated safety shut-off valve for fuel gas service.
• Fast-opening and tight-sealing design for high reliability.
• Available in normally-closed or normally-open configurations.
• Supports general-purpose, non-incendive, and intrinsically safe area classifications (ATEX and Division-rated models available).
• Offered in both standard and high-pressure body constructions.
