Steel full-bore (bore diameter equals the nominal pipeline diameter) ball valves 11s41p PN 16 are used on pipelines as shut-off devices that completely block the flow of working media. The operating principle involves rotating the ball through a 90° angle. In the open position, the axis of the ball's bore aligns with the pipeline axis, allowing media to flow freely through it. In the closed position, the ball rotates so that its wall completely blocks the flow.
The valve marking is decoded as follows:
- 11 – valve type (ball valve);
- s – body material (carbon steel);
- 41 – model number;
- p – sealing material (plastic).
Design Features
- Valve repairability, as it features a split body design.
- The ball mechanism is made of stainless steel, preventing corrosion and extending the device's service life.
- Face-to-face and connection dimensions of 11s41p DN 50, 80, 100 valves match those of gate valves 30ch6br, 30ch6bk, and 30s41nzh.
- In addition to diameters that allow gate valve replacement, this product line includes diameters with standard bore (reduced bore design).
Applications
- In municipal heating systems, the 11s41p ball valve is installed to shut off heat carrier supply during maintenance.
- At chemical plants, it's used to block flows of process liquids.
- In gas pipelines, it serves as a shut-off element to prevent gas leaks.
- At oil refineries, it controls flows of crude oil or finished products.
