영하 196℃ 초저온배관에 사용되는 밸브로서 Packing의 동결방지를 위하여 Bonnet길이를 길게하여야 하며Sub-Zero처리를 하여 실온에서 변형이 가는것을 사전에 방지하여야 한다.Globe Valve의 용도는 유량이나 압력을 조절하는 목적으로 주로 사용된다.
■ YOKE SLEEVE
The standard material of the Yoke Sleeve is Nodular Ni-resist D2 with over a 1150℃(2100℉) dissolution point in conformity with API Std. Specifications.
■ BOLTING
The body-bonnet bolts are manufactured in accordance with API Std. 600 specifications. The nuts also strictly conform with ANSI B1.1 Strain-hardened austentic stainless steel.
■ BONNET
Austenitic stainless steel used for bodies and bonnets ofter excellent impact strength, minimize heat loss and protect against corrosion.
■ STEM
The heat treated stem delivers adequate mechanical properties as well as excellent surface hardness. Further, opening shutting friction is minimized by accurate machining and lapping.
■ DISC
The disc of our globe valves is a loose disc and can freely revolve around the stem. This prevents friction and galling with the seating surface when the valve is shut. The disc is furnished with a conical seating surface that has been ground and lapped to mirror finish. Stellite 6 for all medium and high pressure application prevents seizing and galling.
■ SEAT RING
Stellite 6 for all medium and high pressure application prevents seizing and galling.
■ BODY
Austenitic stainless steel used for bodies and bonnets offer excellent impact strength, minimize heat loss and pretect against corrosion
