Vertical check valve H42W-16P Carbon steel/cast iron/stainless steel

https://owlice.en.made-in-china.comThe H42H/W stainless steel flange vertical check valve is normally closed. Due to the pressure of the inlet medium in the pipeline, the spring resistance is overcome to open the valve. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the spool to the seat and closes the valve, preventing the medium from flowing back, so it acts as a stop.  Length of valve external structure and end face dimension of connecting flange:modelinside nominal diameter DNMain connection dimensionsLDD  1D  2D  6bff  1Z-cpdHH42W-16P  H42W-16R4020014511085 162 4-189550230160125100 162one4-1810565290180140120 182one4-1812080310195165135 203 8-18130100350215180155 203 8-18140125400245210185 223 8-12155150480280240210 243 8-23180200600335295265 263 12-23215modelinside nominal diameterDN(mm)size (mm)L1L2L3DD1D2bfZφH42W-25 PH42W-25R15 858595654516 4φ1420 9595105755516 4φ1425 100105115856516 4φ1432 1051501351007816 4φ1440 1151601451108818 4φ14501401251701601251002034φ14651601451801801451202238φ18801851552001951601352238φ181002102102102301901602438φ23125 2752752752201882838φ251503002253003002502183038φ2520038038038036031027834312φ25 Frequently asked questions:1.
