Tilting Disc Valves
The check valve is a reliable metal seated non-return valve with oblique seating angle widely used in industries such as:
- Pulp and Paper
- Wastewater treatment Plants
- Food and Beverage etc.
Main features:
- Short Face to Face
- Minimum pressure drop
- Low pressure opening allowance
- Good sealing
- Quick operation (inclined seat reduces the stroke distance)
Accessories:
- Auxiliary spring
- Counterweight
- Shock absorber
Sizes: DN 40 to DN 900 (larger diameters on request) Working pressure:
- DN 40 to DN150: 25 kg/cm2
- DN 200 to DN500: 16 kg/cm2
- DN 600 to DN900: 10 kg/cm2
Standard flange connection:
- DIN PN 10
- ANSI B16.5 (class 150)
- Other flange connections are available on request.
