Buy Bellows Control Valve Y44H/Y44T – Class 16 – Carbon/Stainless Steel – Flanged – Manual
The Y44H/T Bellows Pressure Reducing Valve from VALVEHU is designed to provide precise downstream pressure control in steam, air, and non-corrosive media pipelines, especially at temperatures below 180°C. This valve is a reliable choice in industrial systems where stable outlet pressure and high sealing performance are essential.
The Y44H and Y44T models integrate a bellows-type design that isolates the control chamber from the process media, which significantly improves sensitivity and lifespan. Manufactured in stainless steel and carbon steel options, this valve is ideal for medium-pressure applications. Its flanged connection offers ease of installation and secure mechanical strength, making it compatible with various pipeline setups. The internal flow path and regulating mechanism are optimized to reduce pressure efficiently while maintaining stable outlet flow.
The bellows pressure reducing valve functions by adjusting the pressure via the internal spring-loaded control assembly. The difference between the inlet and outlet pressure must be greater than or equal to 0.5 bar to ensure consistent performance. The product complies with GB/T12244-2006 for design and GB/T12221-2005 for structure length, ensuring durability and standardization.
This control valve offers excellent compatibility with steam and gas media, thanks to its stainless steel bellows and valve components, and is engineered for operational safety and maintenance simplicity.
For businesses seeking a reliable, high-quality solution in pressure regulation, this model offers long service life, accurate control, and robust performance.
