Wenbao Valve / WBV Industrial Pipeline Valves & Fully Welded Ball Valves

Technical specifications and global distribution of industrial pipeline valves manufactured by Wenbao Valve Co., Ltd. (WBV): fully welded ball valves DN15-DN1200, forged steel valves, and automated assemblies.

Wenbao Fully Welded Pipeline Ball Valves

Wenbao fully welded ball valves are engineered from carbon steel 20 and A105 for pressures PN16–PN40 and sizes DN15–DN1200. The welded three-piece body eliminates emissions in district heating networks. Stainless steel balls 304/316 with PTFE+C seats withstand severe hydraulic cycling.

Fully Welded Body Architecture for District Heating Networks

Wenbao Valve Co., Ltd. has manufactured industrial valves since 1985, engineering fully welded pipeline ball valves for municipal heating systems and gas transmission pipelines.

The body is fabricated from three forged carbon steel sections (Grade 20 / ASTM A105) joined by automated submerged arc welding. The welded body eliminates external flange connections, preventing emissions and providing reliable pipeline service.

API 6D Forged Steel High-Pressure Ball Valves

The Wenbao (WBV) forged steel valve series is designed for operating pressures up to Class 600 (PN100), serving petrochemical refineries, power generation, and high-pressure steam lines.

Dense forged grain structure in carbon steel A105 and stainless alloys F304/F316 prevents micro-porosity under severe pressure cycling. Valves feature integrated anti-static earthing and API 607 fire-safe metal-to-metal secondary seating.

Compact Wafer Thin Ball Valves Series Q71F

Wenbao Q71F series Clamp Thin wafer ball valves are engineered for compact installation in modular heat exchangers, pumping skids, and confined process plants.

The ultra-short face-to-face dimensions reduce overall assembly weight and length by up to 60 percent compared to standard flanged valves, while mounting directly between ASME, DIN, or GOST companion flanges.

Automation with Pneumatic and Modulating Electric Actuators

Wenbao ball valves incorporate standardized ISO 5211 direct mounting pads for direct coupling with quarter-turn actuation systems without requiring external brackets.

Skids can be equipped with Q671F pneumatic double-acting or spring-return cylinders with 4-20 mA electro-pneumatic positioners, or Q971F intelligent modulating electric actuators featuring manual handwheels.

Quality Verification, Hydrostatic Sizing and Mechanical Testing

Manufacturing operations in Wenzhou adhere to ISO 9001 and European Pressure Equipment Directive PED/CE requirements. Every production unit undergoes shell hydrostatic testing and zero-leakage seat air testing.

The factory testing center utilizes WEW-300B hydraulic universal testing machines and automated cycling rigs to verify tensile integrity and endurance through more than 20,000 full operating cycles.
