What is the difference between valve j941H-40 and j41H-40?
J941H-40 is an electric globe valve, flange joint, inner part 13Cr, material carbon steel, pressure 40 kg and 4.0MPa, 9 represents electric, 4 represents flange, 1 represents straight through, and J41H-40 is common flange connection
I see "valve design manual" category code table, in front of 9 of the electric drive, no 9 is the ordinary hand wheel drive.
The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one
