With integrated flange ends for safe bolt-on installation and quarter-turn operation, Zhongcheng Machinery's Flanged Stainless Steel Ball Valve provides enterprise-grade flow control. This valve's full bore design, which lowers flow resistance and preserves effective fluid transfer throughout pressure ratings from Class 150 to Class 2500, is made of high-quality SS304/SS316 materials.
Our valve functions reliably in temperatures between -29°C and 200°C and employs state-of-the-art sealing technology for tight shutdown performance. We offer corrosion-resistant valves certified under ISO9001/14001/45001, HSE, TÜV, and BV standards. We can create 200 sets annually and have more than 30 years of manufacturing expertise. Every device is put through rigorous API 598 pressure testing to ensure zero-leakage performance in demanding drilling mud circulation and oilfield solid control systems.
Our products conforms to international standards, including ASME B16.34 for wall thickness and API 6D for pipeline service applications. The full bore structure lowers turbulence and pressure loss, and wear-resistant body architecture adapts to slurry that contains solid particles.

Your Flanged Stainless Steel Ball Valve's premium-grade stainless steel construction shields it against chemical and environmental damage. To increase SS316 steel's resistance to chloride on offshore platforms and in marine conditions, molybdenum is added. The passive chromium oxide layer provides long-term protection against oxidation. This extended service life significantly reduces your maintenance costs and system downtime.
A carefully machined spherical disc ensures tight metal-to-metal contact during closure. The valve maintains zero-leakage performance at the high pressure and high vibration conditions found in industrial pipes.Fire-safe design features comply with API 607 standards. If primary PTFE seats fail during thermal events, secondary metal seals prevent catastrophic fluid release automatically.
Maximum throughput capacity is maintained and flow constraints are removed using a full bore design. When compared to reduced bore options, this design reduces pressure drop over the valve body. Because the cavity's interior surfaces are smooth, less solid deposition takes place there. Throughout the valve's service life, your system benefits from reduced pumping costs and increased operational efficiency.
In large pipe sizes, flanged connectors offer better structural stability than threaded joints. Bolt-on attachment makes removal for inspection simple and does not interfere with other piping sections. Smooth quarter-turn action with low torque requirements is made possible by precision-threaded stems. For increased safety in dangerous areas, anti-static devices provide electrical continuity between the ball, stem, and body.
Your drilling operations benefit from our valve's ability to handle aggressive hydrocarbons and drilling mud containing solid particles. The wear-resistant body construction withstands abrasive slurry in solid control systems and mud circulation pipelines.
Suitable for low-pressure to high-pressure applications on various drilling rig models. The valve provides reliable shutoff sealing that prevents environmental contamination at wellhead and flowline installations.
Process industries require valves that resist corrosive media and maintain sterile conditions. Our SS316L grade Flanged Stainless Steel Ball Valve offers non-reactive properties essential for pharmaceutical manufacturing.
CIP (Clean-in-Place) sterilization procedures are not detrimental to the valve. A smooth inside finish makes it easier to thoroughly clean between production batches and inhibits the growth of microorganisms.
Because of its strong resistance to chloride-induced pitting, this valve is the industry standard for seawater handling systems. For desalination plants and offshore platforms, its resistance to corrosion in harsh saltwater conditions is crucial.
Thermal expansion, which is typical in temperature-varying marine applications, is accommodated by the flanged design. Despite constant exposure to harsh marine environments, your systems remain intact.
Municipal water facilities and industrial wastewater treatment plants utilize our valves for reliable flow isolation. The robust construction ensures consistent performance across varying water chemistry conditions.
Full compliance with drinking water regulations makes these valves suitable for potable water distribution networks. Long service intervals reduce maintenance burden for utility operators.
Zhongcheng uses a multi-phase inspection procedure to make sure your valve satisfies strict safety requirements. To confirm the accuracy of the alloy composition, each unit is subjected to Positive Material Identification (PMI) testing.
Hydrostatic and pneumatic pressure testing follows API 598 procedures strictly. We perform both shell and seat leakage tests to ensure zero fugitive emissions and environmental compliance.
Dimensional verification against ASME B16.10 confirms face-to-face compatibility with your existing piping systems. Surface finish inspection checks Ra values to eliminate casting defects or burrs that could compromise performance.
We have ISO 9001 Quality Management, ISO 14001 Environmental Management, and ISO 45001 Occupational Health and Safety certifications. Additional assurance of production quality is provided by third-party verification from BV and TÜV.
We understand that different applications demand specific configurations. Our engineering team offers flexible customization of valve dimensions, flange ratings, and seat materials to match your process requirements.
Choose from domestic or international motor brands for actuated versions. ISO 5211 mounting pads enable seamless integration with pneumatic or electric actuators based on your automation needs.

Comprehensive Technical Package:
Q: Why choose flanged connections over threaded joints for stainless steel ball valves?
A: In big pipe sizes, flanged connectors offer easier installation and more structural stability. They successfully stop leaks brought on by vibration or thermal expansion, which endanger threaded joints in high-stress applications.
Q: How do I select between SS304 and SS316 materials?
A: Compared to SS304, SS316 is more resistant to chlorides and marine conditions because it contains molybdenum. Choose SS316 for seawater, coastal locations, or chemical processes involving chlorinated chemicals.
Q: Can these valves be automated for remote operation?
A: For smooth integration with pneumatic or electric actuators, ISO 5211 mounting pads are included in the majority of combinations. Remote control and integration with automated process control systems are made possible by this.
Q: What maintenance intervals should I expect?
A: The robust design extends operational lifespan significantly. Typical packing replacement occurs every 2-3 years depending on cycle frequency. Full bore design minimizes wear from fluid turbulence.
Q: How does the fire-safe design protect my facility?
A: Secondary metal-to-metal seals stop catastrophic fluid loss in the event the primary PTFE seats melt during fire exposure. API 607 testing is used to confirm this design's improved safety compliance.
