Stainless Steel Rising Stem Flange Gate Valve BZ44W-16P Working Principle

The gate valve's gate moves linearly with the valve stem, known as a rising stem gate valve (also called an open stem gate valve). Typically, the rising stem features a trapezoidal thread that converts rotational motion into linear motion via the nut at the top of the valve and the guide groove on the valve body, transforming operating torque into operating thrust. The sealing surface can rely solely on medium pressure for sealing, meaning the medium pressure presses the gate's sealing surface against the opposite valve seat to ensure sealing, which is self-sealing. Most gate valves use forced sealing, meaning when the valve is closed, external force is required to press the gate against the valve seat to ensure sealing integrity.

Stainless Steel Rising Stem Flange Gate Valve BZ44W-16P Features

1. Meticulous material selection, complying with domestic and international standards, ensuring high overall material quality.

2. Meets the requirements of advanced domestic and international standards, offering reliable sealing, excellent performance, and an aesthetically pleasing design.

3. Advanced and rational sealing pair matching; the sealing surfaces of the gate and valve seat are hard-faced with Stellite cobalt-based hard alloy of varying hardness, ensuring reliable sealing, high hardness, wear resistance, high-temperature resistance, corrosion resistance, excellent anti-galling properties, and long service life.

4. The valve stem undergoes quenching and tempering as well as surface nitriding treatment, providing good corrosion resistance, anti-galling properties, and wear resistance.

5. Features a wedge-type elastic gate structure; medium and large diameters are equipped with thrust bearings, reducing friction, and include an impact manual mechanism for easy and smooth operation.

6. Compatible with various piping flange standards and flange sealing surface types, meeting diverse engineering needs and customer requirements.
