The JOEPAI stainless steel monoblock ball valve is specifically designed for precise flow control of liquids and gases. Its single-piece body construction ensures high leak-tightness and eliminates weld points, significantly reducing the risk of leaks.
A perforated ball inside the valve rotates to start or stop the flow. Operation can be performed manually via a lever or automatically using an actuator. The robust stainless steel body offers excellent resistance to corrosion and wear, ensuring long-lasting performance with minimal maintenance.
Monoblock ball valves are widely used across industrial and commercial applications, especially in pipelines carrying chemical substances.
Common applications include:
∙ Water treatment plants
∙ Steam lines and pressurized gas systems
∙ Food and beverage industry (hygienic design)
∙ Pharmaceutical and petrochemical facilities
∙ Marine engines and power plants
The compact monoblock design allows easy integration into space-constrained systems and ensures safe operation under high temperatures and pressures.
The stainless steel monoblock ball valve contains a spherical ball with a central hole, rotated via a stem. When the hole is aligned parallel to the pipeline, flow is released; when perpendicular, flow is completely stopped.
This rotation can be done manually or with an automatic actuator. The design ensures a high-integrity seal between the ball and seat, providing safe operation even during sudden pressure changes.
Monoblock ball valves are available in various sizes and pressure ratings. General specifications include:
