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 the medium, the force of the valve is larger than the force of the open valve, so the diameter of the stem should be large, otherwise the stem top bending fault will occur
