Yt11H Increase the sensitivity of the thin film type pressure reducing valveDetailed product description：

Yt11H enlarged thin film high-sensitivity pressure reducing valve is particularly suitable for pipelines with large changes in inlet pressure and outlet flow rate, requiring stable outlet pressure. The Yt11H high-sensitivity pressure reducing valve is developed based on similar foreign products and belongs to the direct acting diaphragm spring pressure reducing valve. Its outstanding feature is that it greatly increases the working area of the diaphragm. Therefore, compared with similar pressure reducing valves, the diaphragm has a particularly obvious sensing effect on downstream pressure changes. Even small changes in downstream pressure (such as 0.01MPa) will cause significant adjustment actions of the diaphragm and valve core, greatly improving the pressure stabilizing function.
