Y43H pilot piston steam pressure-reducing valve

This series of valve, made up of main valve and guide valve. Main valve made up of valve seat, main valve plate, piston, spring and other components. Pilot valve mainly made up of valve seat, valve disc, diaphragm, spring, adjusting spring and other components. Setting entrance pressure through regulating regulation spring, adjust throttling area of main valve through drive piston of pilot valve, reduce and regulate pressure
