Manufacturer JOEPAI Produced Wafer Type Monoblock Ball Valves with ISO 5211 Direct Mounting Pad are compact fluid control devices clamped directly between pipe flanges, ideal for space-constrained and weight-sensitive applications such as offshore oil platforms and chemical processing plants. With a 90° manual rotation, these valves offer excellent sealing performance, high flow capacity, low flow resistance, and long service life. They are suitable for gas, liquid, steam, sewage, and fibrous media. JOEPAI integrates precision casting technology with strict quality control, backed by ISO 9001 certification and global exports. With strong production capacity, JOEPAI ensures reliable delivery for demanding industrial projects.

1. Compact & Space-Saving Design
The Wafer Type Monoblock Ball Valves with ISO 5211 Direct Mounting Pad features a compact structure that takes up significantly less space in the pipeline — up to 30–50% less space than traditional flange-to-flange ball valves. This makes it ideal for space-constrained installations.
2. No Body-to-Cover Joint – Reduced Leakage Risk
Unlike conventional ball valves, the single-piece monoblock body has no connection between the body and the cover, eliminating potential leak paths and enhancing system safety and reliability.
3. Flexible Actuator Compatibility
Equipped with ISO 5211 direct top flanges, the valve can be seamlessly integrated with pneumatic, electric, or hydraulic actuators, in addition to manual lever operation.
