Straight-through Globe Valve |
Direct Flow Globe Valve (Y Valve) |
Application:
It is used in vapor system for hydrophobicity, degassing, nitrogen filling, dosing and sewage disposal.
Structural Features:
◇ The valve body and bonnet are made of integral die-forged parts;
◇ The valve body and bonnet are connected by clamping structure and fixed by stainless steel set screws;
◇ Valve body, disc sealing surface surfacing Stellite carbide, hardness HRC ≥ 40, sealing vice hardness difference about HRC3-5, surfacing layer thickness 3-5mm;
