Steel & O’Brien Sanitary Check Valves

Steel & O’Brien sanitary check valves are engineered to allow fluid to flow in a single direction while preventing reverse flow that can cause cross-contamination or equipment damage.

Valve Types and How They Work

  • Spring Check Valves: Use a spring-loaded shutter to seal the valve when flow reverses.
  • Ball Check Valves: Rely on gravity to move a ball into the flow path, blocking reverse movement.
  • Air Blow Check Valves: Use pressurized air to open a rubber plug; when air stops, a spring returns the plug to seal the valve—ideal for CIP systems and tank agitation.

All models are easy to maintain, disassemble, and clean, supporting efficient operations and uptime.
