STRUCTURAL FEATURES

◎ Body and Bonnet Connection
The body and bonnet of Class150～Class900 globe valves are usually with studs and nuts. And the body and bonnet of Class1500～Class2500 globe valves are usually of pressure seal design.

◎ Packing Seal

Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2μm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and com-pactness (Ra 0.8μm) and ensure the reliable tightness of the stem area.

◎ Stem Nut

Usually, the stem nut is copper alloy. It is also can be made of ASTM A439 D2 if being requested by the customer. For large sized globe valve, rolling bearing is fitted at the two sides of stem nut in order to minimize the open and close torque of the globe valve.
