Reactor Bottom Valve
Description
REACTOR BOTTOM VALVE
Tank Bottom Outlet Valve | Y- Type Flush Bottom Valve | SS304 / SS316 | PN10 β PN40
MNC Industrial Valves manufactures high-performance Reactor Bottom Valves designed for complete discharge of fluids from chemical reactors, process vessels, and storage tanks.
These valves are installed directly at the lowest point of reactors or vessels, allowing complete draining of process fluids without leaving dead volume inside the vessel nozzle.
Reactor bottom valves are essential in batch processing plants, where complete discharge of product after each process cycle is required to prevent contamination and ensure process efficiency.
These valves are widely used in chemical plants, pharmaceutical manufacturing, specialty chemicals, petrochemical plants, and food processing industries.
PRODUCT OVERVIEW
The valve ensures zero dead space discharge, preventing accumulation of chemicals inside the reactor outlet.
SIZE RANGE
Manufacturing Range: DN 25 β DN 200
Typical configurations include:
DN 50 Γ DN 80
DN 80 Γ DN 100
The outlet size may be larger to improve discharge flow.
PRESSURE RATING
Available Pressure Ratings: PN10, PN16, PN25, PN40
Pressure rating depends on reactor design pressure and flange standards.

MATERIAL OF CONSTRUCTION (MOC)
SS316 is preferred for corrosive chemical environments.
Temperature Range: Typical operating temperature β20Β°C to +250Β°C. Higher temperature options available depending on seat material selection.
DESIGN FEATURES
- Flush mounting on reactor bottom

- Leak tight sealing system
- Smooth discharge flow path
- Suitable for viscous and slurry media
- Long service life
- Low maintenance requirements
WORKING PRINCIPLE
Reactor Bottom Valves operate by lifting the disc away from the seat using a threaded stem mechanism.
Operation sequence:
- Handwheel rotation lifts the stem
- The disc opens the outlet port
- Process fluid discharges through the outlet nozzle
- When closed, the disc seals against the seat
This design ensures complete discharge of reactor contents.
