T40H-10, T40H-16, T40H-25 manual control valves: applies to the work pressure is 1.6MPa, the medium temperature ≤ 200 ℃ (and ≤ 2.5MPa, medium temperature ≤ 350 ℃) of steam or hot water pipe as regulating the flow of. According to rotate the hand wheel clockwise to close the manual control valve, when the valve rod drives the valve down, straight to two conical sealing contact to close the pipeline closed.
Product features: ① to improve supply condition: all the branches and thermodynamic point manual control valve can be according to design flow regulation, achieve the temperature condition is good, the valve gate valve, globe valve than good regulating performance, it has an approximate linear regulation performance. Therefore, the heating of buildings uneven phenomenon effectively improve. The save energy: heat pipe network due to temperature stress disorder, causing some branch flow is too large, so that some construction temperature is too high, the user had to open the window, to achieve the purpose of saving energy. Improving the management of hydraulic conditions: manual adjustment valve is controlled according to the rated flow of the excess flow of network management, operation is reduced, the original water conditions have deteriorated to get some improvement.
Y43H-40, Y43H-63 type pilot valve piston steam: the flange connection, the piston type structure form, the valve seat sealing surface material for Cr13 stainless steel, nominal pressure PN40~PN63, valve body materials for WCB steam pressure reducing valve.
Y43H-40, Y43H-63 type pilot valve piston steam from the main valve and pilot valve composed of two parts. Mainly by the main valve seat, the main valve plate, piston, spring and other parts. Mainl
