Shandong Yuhong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of tank bottom discharge valve in China. We have world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale bulk high-grade tank bottom discharge valve from our factory.
A tank bottom discharge valve mounts directly at the vessel outlet of reactors, storage tanks, and mixers where complete drainage matters. It cuts product residue and shortens cleaning, for chemical, pharmaceutical, food, and fine-chemical service.
A standard globe valve sits below the outlet nozzle and leaves a cavity where product collects after discharge. For sticky, resinous, polymeric, or crystallizing media that is not just a cleaning nuisance - it hits product quality and safety. The bottom-mounted design keeps the internal passage nearly level with the tank floor, so product drains out and leaves far less behind.
Many of these valves also regulate, not just isolate. Beyond opening and closing, they hold a steady discharge rate for batch reactors, mixing tanks, and dosing - useful where flow must stay controlled through the run. We review medium, temperature, pressure, flow, pipe size, and discharge needs, calculate Cv, and pick the trim so the valve fits both the process and the vessel.

Key Features
Built for the Bottom Outlet
The valve sits right under the vessel outlet. Compared with a standard globe valve, the flow passage runs closer to the tank floor, so less liquid stays behind and emptying is more complete.
Handles High-Viscosity Media
Some media flow slowly; others thicken as they cool. A conventional outlet valve traps a lot of material in the vessel. The bottom design lets product leave more fully - less waste, easier next batch.
Easy to Clean
Many lines clean the tank after every batch. The smooth passage washes out better; less residue means shorter cleaning and lower water or solvent use.
Trim to the Media
Clean liquids take standard trim. Viscous or particle-laden products get an optimized internal structure for better flow and less chance of blockage.
Applications
- Chemical reactors
- Mixing tanks
- Storage tanks
- Batch reactors
- Polymer production
- Resin manufacturing
- Pharmaceutical vessels
- Food processing tanks
- Cosmetic production
- Fine chemical plants
Manufacturing & Quality Control
The body is machined to match the tank connection accurately:
- Sealing surfaces re-inspected before assembly for reliable shut-off
- Hydrostatic test, seat leakage test, and stroke test before shipment
Documentation available per project: material certificates, pressure test reports, and inspection records.
Packaging & Shipping
Each valve is cleaned before packing and the sealing face is protected against transit damage. Large valves ship in export wooden cases; smaller sizes per your requirement. Packing photos and ID labels are sent before shipment.
Procurement Notes
Matching an existing reactor
In most projects the connection dimensions are built to the vessel drawing, so retrofits are straightforward.
Maintenance
Internal parts service without replacing the body - plug, seat, and seals swap out, which lowers lifecycle cost.
Sticky or crystallizing product
Our engineers may specify a special trim or body material from the operating conditions.
FAQ
Q1: Can this valve completely empty the tank?
It is designed to minimize retention. Actual performance also depends on vessel structure and install position.
Q2: Is it suitable for viscous media?
Yes. It is widely used for resins, polymers, adhesives, and other high-viscosity products.
Q3: Can it be installed on an existing reactor?
Often, yes. Connection dimensions are built to the equipment drawing.
Q4: Can the internal trim be replaced?
Yes. Plug, seat, and sealing parts are replaceable during maintenance.
Q5: Can this valve be automated?
Yes. Pneumatic and electric actuators are both available to suit the control system.
Q6: What do you need to quote?
Medium, temperature, pressure, flow rate, tank outlet size, and connection standard.
Why Choose Yuhong Valve
Tank bottom valves are usually custom, because no two vessels are the same - a catalogue valve may not match the reactor outlet or the discharge performance you need. We work from your drawing or spec so the valve fits the connection and the process; before production we calculate Cv so it controls steadily while it drains.
Equipment makers value consistency, so for repeat projects we keep records and drawings on file - future orders stay compatible with earlier equipment. Material certificates, inspection reports, and pressure test records support your documentation and acceptance.
