The manufacturing dimensions and pressure ratings of the WCB Floating Ball Valve with Flanged Connection comply strictly with API 6D and ASME B16.34 standards to ensure system compatibility and mechanical safety.
Cast carbon steel (ASTM A216 WCB) provides exceptional mechanical strength, pressure containment, and thermal stability up to 425°C.
Under line pressure, the floating sphere shifts slightly downstream, pressing firmly against the resilient outlet seat ring to achieve tight shutoff.
The stem is installed from inside the valve body with an integral shoulder, preventing stem ejection during abnormal pressure spikes.
Allows complete internal maintenance, sphere polishing, and seal replacement without replacing the entire valve body assembly.
Carbon steel (WCB) provides high structural integrity and pressure resistance at a practical cost compared to full stainless steel bodies. Combining a WCB body with SS304, SS316, or 13Cr stainless steel internal balls and stems prevents corrosion, surface scoring, and galling when handling non-corrosive or mildly aggressive industrial liquids, steam, water, and oil.
The valve body features an ISO 5211 mounting pad option. This standardized top platform allows direct mounting of pneumatic or electric rotary actuators without requiring custom brackets or shaft couplings, simplifying automated line setup.
The pressure endurance and chemical stability of the WCB Floating Ball Valve with Flanged Connection fit critical fluid control networks:
Controls fuel flow across oil transmission lines, gas metering manifolds, and distribution manifolds.
Manages non-corrosive hydrocarbons, industrial solvents, and process air. High-corrosion environments can be equipped with stainless steel CF8/CF8M body materials.
Provides dependable isolation across high-temperature steam networks, boiler feedwater lines, and condensate systems.
Demonstrates long-term mechanical durability in municipal water plants, industrial filtration setups, and high-frequency slurry lines.
Zhejiang Zhongguan Valve Manufacture Co., Ltd. operates complete internal production lines, including precision CNC machinery, automatic spray lines, dedicated sleeve installation setups, and heavy-duty pressure testing equipment.
Extended stem configurations suit underground buried piping or thick thermal insulation layers.
Optional padlockable handle devices prevent accidental manual operation on critical media lines.
Full manufacturing support for ANSI, DIN, BS, and GB flange connections to fit localized piping requirements.
Leveraging a northern water valve supply chain (primarily cast iron) and a southern industrial valve manufacturing base in Wenzhou (cast steel and stainless steel), Zhongguan supplies projects and stockists across Southeast Asia (Vietnam, Malaysia, Singapore) and global markets.
Single-unit maintenance orders and large project packages are produced with equal care.
Standard inquiries receive full quotation proposals within 24 hours. Dimensional CAD drawings are available upon technical request.
All products carry ISO certifications and a 1-year quality warranty, including free replacement for verified manufacturing defects. Review our certificates for more detail.
