What is the difference between globe valve model WJ and J

What is the difference between globe valve model WJ and J

The modeling method for globe valves was developed from international valve modeling standards.

　　Globe valve type representation:

　　Globe valve additional code: w bellows, d low temperature, b insulation;

　　1) Globe valve category code: j for globe valve;

　　2)Globe valve transmission mode: manual without code, 5 bevel gear, 6 pneumatic, 9 electric;

　　3)Connection mode of globe valve: 4 flange connection, 6 welding;

　　4)Structure form of globe valve: 1 through, 2 Z through, 3 through, 4 angle, 5 Y through, 6 balanced through, 7 balanced angle.

　　type, 8 needle type;

　　5)Globe valve sealing material: direct processing F fluorine rubber, H stainless steel, N nylon plastic, Y carbide, M monel alloy, W valve body;

　　6)Nominal pressure of globe valve: 16 means 1.6mpa and 16 kg of pressure, PN1.6-32mpa, IN150LB-1500LB, 5-63k;

　　7) Globe valve body material: A titanium alloy, C carbon steel, I chromium molybdenum steel, P stainless steel 304, R stainless steel 316;

　　For example: WJ41H-16C bellows disconnecting valve, W bellows, J disconnecting valve, 4 flange, 1 through type, H stainless steel, 16 pressure 16 kg, carbon steel.
