YT11Htype

This series valve is developed by reference to similar foreign products, belong to the direct acting type film spring pressure reducing valve, its outstanding characteristic is high sensitivity pressure reducing valve is greatly increased the diaphragm working area, therefore, compared with the same kind of pressure reducing valve, diaphragm sensor to the downstream pressure change obviously, small changes in the downstream pressure (for example, 0.01 MPa) will cause the diaphragm and the valve core obvious adjust action, thereby greatly improving the voltage regulation function. This series of products are especially suitable for pipelines with large changes in inlet pressure and outlet flow, which require good and stable outlet pressure.

Note: parameters are for reference only, or incomplete. Valves can be selected according to the requirements of different pressure, material, diameter, driving mode. Please contact us by phone or online.
