Which brand of drain valve is good

The drain valve of w&T is quite good.

Boiler blowdown valve, simply put, during the operation of the boiler, impurities, salts and sludge that are constantly concentrating in the water need to be discharged in a timely manner. If the pipes are not drained thoroughly or improperly, it will lead to: scaling of the boiler pipes and a decrease in heat transfer efficiency; The quality of the boiler water has deteriorated, and the steam carries salt. In severe cases, it can cause pipe burst and boiler corrosion.

There are generally three types: bottom drain valve, continuous drain valve and purge drain valve.

The harsh working conditions that need to be addressed include flash evaporation, cavitation, and high-flow erosion, etc. The W&T blowdown valve solution - specifically designed to address "flash evaporation, cavitation, and erosion", adopts an angular valve body structure + Venturi flow expansion design, integral valve stem & valve core design, sleeve guiding structure, CASCADE multi-stage pressure-reducing valve core to resist cavitation, and a quick-release maintainable design.

W&T does not produce "universal" valves - we only provide verified and effective solutions for real working conditions - flash evaporation, cavitation, high temperature, erosion.
