RUF3 Series - Check Valves

Product Type(s) : Check Valves
Description :

The RUF Series Check Valve is used in places where a return flow of product in pipelines must be avoided.  This check valve is utilized in brewery, dairy, chemical and pharmaceutical processing.

WHERE TO BUY

FEATURES

Advantages

  • Reduced maintenance cost due to robust and reliable bearing. The valve has minimal parts.
  • Flexible design - the valve can be installed horizontally or vertically.
  • Easy to maintain - the intermediate flange design means that the valve can easily be removed from the line.
  • Profile seals with ID markings that eliminate gaps and facilitate ordering of spares.
  • Minimum flow resistance/pressure drop
  • Smooth flow due to ball-shaped valve body
  • Minimum response pressure at 0.72 psi (0.05 bar)
  • Full opening cross-section at 1.16 psi (0.08 bar)
  • Designed for CIP cleaning
  • Soft seat seal
  • The RUF3 check valve is designed for direct welding into process pipelines
Theory of Operation

Non-return check valve working principle


A non-return valve is used in places where return flow of product in pipelines must be avoided.

The valve opens by pressure of the liquid against the spring-loaded valve disc. The closing process is initiated by the preloaded spring when the liquid flows in the flow direction stops.

Components of the RUF3 non-return check valve:

  1. Flange
  2. Flange screw
  3. Flange seal
  4. Shaft bearing
  5. Housing seal
  6. Pressure spring
  7. Valve shaft
  8. Seat seal
  9. Valve body

Key Applications

Used to prevent return flow of liquids, can me used in multiple industries.

Dairy Processing

Brewery Processing

Pharmaceutical Processing

Chemical Processing
