Designed for reliable, low-residence discharging and sampling from the bottom of reactors, tanks and process vessels, this manual-operation tank-bottom angle valve (bottom flush / slurry angle valve) provides fast, dead-space-free draining and feed control. The valve can be welded directly to the vessel or installed using the bottom flange, and is available with flange connections meeting ASME standards.
Key features
- Integrated-body construction for robust use in industrial service
- Disc opens into the tank for thorough discharge; available outlet angles: 45°, 50° and 90°
- Rotation-resistant stem guidance to ensure straight-line stem motion and prevent twisting
- Wear-resistant protection plate and cemented-carbide (or tungsten-coated) sealing faces for superior erosion and corrosion resistance
- Auxiliary line sealing to improve overall seal reliability
- Designed for easy installation either welded or flange-mounted at the tank bottom
