ZC Tank Bottom Valve serves as a critical control component for mud tank suction manifolds in drilling operations. Designed for storage, circulation, and precise switching of drilling fluids, this valve installs within mud tank suction manifolds to control fluid flow, prevent backflow, and enable independent operation of individual tanks.
With nominal diameters ranging from 200~400mm and handwheel opening mode, our valve delivers excellent sealing performance and corrosion-resistant construction. Certified under ISO 9001/14001/45001, TÜV, and BV standards, it excels in pipeline manifold control and environmental waste slurry discharge applications. Backed by comprehensive technical support and a 1-year warranty, this valve ensures reliable operation in demanding drilling environments.
Our valve meets stringent industry standards. The table below outlines the core parameters:

The valve stem length can be customized according to your mud tank depth. The handwheel mounts on the operating platform atop the tank, allowing operators to control the bottom valve directly from the tank surface.
Our valve employs a conical valve core with rubber sealing surface. The manual screw downward pressure achieves a tight seal.
With mud pressure assistance inside the tank, the sealing effect enhances as pressure increases. This design effectively prevents mud leakage even in high-solid-content environments.
The vertical long-stick structure adapts to various tank depths. Operators can customize the valve stem length to match their specific requirements.
The handwheel rotation drives the screw mechanism with a large physical-mechanical transmission ratio. This design makes operation remarkably easy for your team.
Operators intuitively judge the valve's opening degree by counting handwheel rotations. The screw height provides immediate visual feedback on valve status.
This transparent operation reduces training time and minimizes errors during fluid switching procedures.
Drilling mud contains abundant solid particles including sand and debris. Chemical additives further increase corrosion risks.
We manufacture valve seats and cores from wear-resistant alloys or specialized synthetic rubber. The valve stem uses chrome-plated carbon steel for extended durability.
This material selection ensures long-term performance in abrasive environments where ordinary valves fail prematurely.
Drilling sites present severe vibration challenges. Our manual screw structure incorporates a self-locking function that prevents accidental opening or closing.
This safety feature maintains process integrity during equipment vibration. Your operations remain secure even during intensive drilling activities.
The valve withstands complex cleaning environments with aggressive caustic chemicals, ensuring consistent performance throughout its service life.
You'll find our Tank Bottom Valve indispensable in oil and gas drilling mud tanks. It controls fluid distribution across multiple tanks in solid control systems.
The valve enables independent tank operation for maintenance without disrupting your entire circulation system. This flexibility maximizes uptime and operational efficiency.
Our solution suits various drilling rigs including ZJ90, ZJ70, ZJ50, ZJ40, ZJ30, and ZJ20 models. It integrates seamlessly with existing mud circulation tank systems.
Tank cleaning operations demand complete drainage without residue. Our full-bore design eliminates sediment accumulation and blockage issues.
When you open the valve, mud and sediments flow out completely. Zero dead volume means no mud residue remains to contaminate subsequent batches.
This characteristic proves particularly valuable in sludge tanks, waste slurry tanks, and horizontal directional drilling (HDD) mud systems where thorough cleaning is mandatory.
Beyond drilling applications, the valve serves fine chemical synthesis environments. Manual operation provides safety during emergency shut-offs when handling viscous polymers.
The high-torque handwheel mechanism breaks through solidified crusts at the tank base—a common challenge with temperature-sensitive materials.
Your team gains precise flow throttling capability for controlled drainage scenarios where automation lacks the necessary tactile feedback.
Zhongcheng Machinery provides complete engineering documentation with your valve purchase. You'll receive detailed component diagrams and installation drawings.
Our technical team offers installation guidance and commissioning support. We ensure proper vertical alignment for optimal drainage performance.
Custom-angled weld-ends are available to match your tank's dish bottom slope. This customization guarantees complete fluid evacuation.
We protect your investment with transport-safe packaging. Each valve receives plastic film wrapping, rainproof tarpaulins, and secure strapping.
Pallets or wooden crates are provided based on your equipment requirements. Our efficient logistics network ensures smooth delivery through Tianjin and Shanghai ports.
In-stock products ship within 3 days. Customized orders deliver within 15 days—industry-leading turnaround times that keep your projects on schedule.
Your purchase includes operation and maintenance manuals in clear language. We provide industry training to ensure your team operates the valve correctly.
Engineering drawings and process flowcharts help integrate the valve into your existing systems. Our professional service team delivers complete project solutions.
The 1-year comprehensive warranty covers manufacturing defects and performance issues. We maintain complete spare parts inventory including seals, handles, and actuators for rapid replacement.
Zhongcheng Machinery's manufacturing facility spans 6,300 square meters in Xingping City, Xianyang. With over 30 years of machinery manufacturing expertise, we maintain stringent quality protocols.
Every valve undergoes Positive Material Identification (PMI) to verify alloy composition matches the Material Test Report (MTR). Surface roughness testing confirms Ra values meet CIP/SIP effectiveness standards.
We perform hydrostatic and pneumatic pressure testing according to API 598 standards. This confirms zero-leakage performance of seat and stem seals under operating conditions.
Dye Penetrant Inspection (DPI) detects micro-cracks in weld areas. These comprehensive tests ensure structural integrity before shipment.
Our ISO 9001 Quality Management System ensures consistent product quality. ISO 14001 Environmental Management and ISO 45001 Occupational Health and Safety certifications demonstrate our commitment to responsible manufacturing.
TÜV and BV approval validates our adherence to international standards. HSE Standards compliance means you can deploy our valves confidently in regulated environments.
All non-metallic gaskets and seals comply with FDA and USP Class VI standards. This prevents media contamination—critical for applications requiring process purity.
Q: Can I upgrade the handwheel to an actuator later?
A: Yes, our modular design allows handwheel replacement with pneumatic or electric actuators. The valve body remains in place, minimizing downtime and installation costs during upgrades.
Q: How often should I replace the valve seat?
A: In standard CIP/SIP cycles, seals typically last 6–12 months. We recommend inspection after every 500 cycles or following high-temperature sterilization procedures.
Q: Does the handwheel lock in position?
A: Professional-grade models include a locking nut or pin. This prevents accidental adjustment during high-vibration processes, maintaining your desired valve position.
Q: What if the valve cannot close tightly?
A: Clean accumulated sediment from the sealing surface first. If the issue persists, replace the sealing gasket. Contact Us at oliver@zcgukong.com for replacement parts guidance.
Q: Is installation at an angle possible?
A: Vertical installation provides optimal drainage. However, we manufacture custom-angled weld-ends to match specific tank bottom slopes when your application requires it.
Q: How do I maintain the valve for maximum service life?
A: Lubricate the screw and moving parts regularly. Open the valve fully and flush with water if blockage occurs. Replace seals proactively based on cycle counts rather than waiting for failure.
Q: What makes this valve better than ball valves or gate valves?
A: Our full-bore design eliminates dead volume that traps sediment. The straight-through flow path provides superior anti-blockage performance in high-solid-content mud compared to conventional valves.
