Wafer Knife Gate Valves
- Our standard wafer knife gate valve is used within many different fields of applications.
- The special shut-off technique of this valve makes it suitable for both fluids and dry media such as pulp, sludge, biomass, powder and different kinds of waste.
- Standard body material: stainless steel or coated nodular iron
- Special body material: Duplex, Hastelloy, 254, SMO and Titanium.
- The valve is equipped with a gate in stainless steel, with different alloys as options.
- The gland box can also be supplied with a box bottom scraper or with double gland for the most demanding applications.
- Valve is designed, manufactured, inspected and tested according to pressure equipment directive 2014/68/EU category I and
II module A2. The valve is CE marked when it is applicable.
