SchuF & Fetterolf Piston Bottom Outlet Valve
SchuF & Fetterolf Piston Bottom Outlet Valve
SUPPLIER: SchuF & Fetterolf
AVAILABILITY: Canada
SchuF ram bottom outlet valves (BOVs) are ideal for draining tanks, reactors or pipelines containing viscous media or where rapid vessel drainage is important. SchuF ram BOV valves are dead space free, without sharp corners or edges, for fast and compete draining. A wide range of materials for body and trim are available to suit application needs. The valves can be cleaned in place through standard flushing ports for easy maintenance.
Design Parameters
- High‑temperature vessel drain
- Polymer melt service
- Reactor discharge
- Slurry and catalyst handling
- Viscous media
- Zero‑dead‑space bottom outlet service
Frequently Asked Questions
Find quick answers to some of the most common questions
How does a SchuF Piston Bottom Outlet Valve eliminate reactor dead space?
The valve’s solid piston extends fully into the vessel drain nozzle, sitting flush with the reactor floor to eliminate stagnant pockets and ensure complete batch mixing.
What is the difference between a Piston-Type and Disc-type Bottom Outlet Valve?
Piston valves retract downward into the valve body for full-bore flow, while disc valves extend upward into the vessel to break through heavy bottom crusts and polymer buildup.
How do SchuF Bottom Outlet Valves handle crusting and solid buildup?
Precision-machined metallic pistons physically break through bottom crusts during stroke movement, supported by optional body flush ports that inject solvent or steam to clear solids.
Can SchuF Piston Bottom Outlet Valves be serviced without unbolting from the reactor?
Yes. Rear-entry bonnet designs allow maintenance crews to extract the piston, stem, and packing sets from below without disconnecting the main body flange from the vessel nozzle.
