Product Description
J41H flanged globe valves are designed and manufactured to API and ASME standards.Globe valve, also known as cut-off valve, belongs to the forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.When the medium from the lower part of the disc into the valve, the operation force needed to overcome the resistance is the friction force of the stem and packing and the thrust generated by the pressure of t...

Summary
The V cut has large adjustable ratio and equal percentage flow characteristic, realizing stable control of pressure and flow.
Simple structure, small volume, light weight, smooth flow channel.
Provided wrth large nut elastic automatic compensation structure to effectively control the sealing face of seat and plug and realize good sealing performance. The eccentric plug and seat structure can reduce wear.
The V cut produces wedge shearing force wrth the seat t...
