This series of pressure reducing valve belongs to the pilot piston type pressure reducing valve. By the main valve and pilot valve two parts. Main valve mainly by the valve seat, the main valve plate, piston, spring and other parts of the composition. The pilot valve is mainly composed of valve seat, valve, diaphragm, spring, adjusting spring and so on. By adjusting the spring pressure to set the outlet pressure, the use of the diaphragm sensing outlet pressure change, through the pilot valve opening and closing the main valve throttle position of the flow area of the size, to achieve the function of pressure relief.
This series of products made the following improvements in the ordinary valve base, increase the piston area, changing the throttle structure, change the seal in the form, structure and improve the pilot valve spring adjustment form to the following aspects of improving the performance of the product.
1, improve the change of the pressure on the export of the sensing performance, improve the sensitivity, greatly reducing the pressure due to upstream pressure changes, flow changes and other factors caused by the pressure deviation.
2, improve the streamline distribution, reduce the noise.
3, improve the sealing surface structure, to extend the life of the sealing surface.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
