API Flanged Stainless Steel Globe Valve

Description
Our API flanged stainless steel globe valve is generally applied in pipelines of all kinds of corrosive media. The flanged globe valves consist of valve body, disc, shaft pin and valve stem. The sealing face appears to be flat or conic. The disc moves along the valve seat central line. Currently, it enjoys wide application in pipelines of tag water, sewage, construction, petroleum, chemical, foodstuff, textile, medicine, electricity, ship, metallurgy, and energy system.

Advantages
1. API flanged stainless steel globe valve has good sealing performance and long service life.
2. Through two shot blasting treatment, the surface is gloss and smooth.
3. The friction between sealing faces is small.
4. Such globe valve adopts precision casting body and CNC processed disc.
5. We offer broad pressure classes including Class 150, Class 300,Class 600, Class 900 and Class 1500.

Features
(1) API flanged stainless steel globe valve has features of simpler structure and easier maintenance when compared with gate valve.
(2) With no relative sliding between disc and valve sealing face, abrasion and scratch are not serious.
(3) The disc stroke is short when flanged globe valves start or stop. Thereby, its height is a bit lower than that of gate valve, while the structure length is longer.
(4) Medium passway is not smooth inside API flanged stainless steel globe valve, so the hydraulic resistance is large, resulting in large power consumption.
(5) When the nominal pressure of medium flow direction is less than 16MPa, medium flows up from lower disc. When the pressure is more than 20MPa, medium flows down from upper disc, strengthening sealing performance. When in operation, medium flow direction is one way and can not be changed.
(6) The valve stem axis of API flanged stainless steel globe valve is vertical to valve seat sealing face.

Classification
1. According to different passway directions, API flanged stainless steel globe valve can be subdivided into straight-through, straight-flow, angle and plunger type.
2. Depending on the thread location on the valve stem it can fall into upper and lower threaded stem type.
3. Basing on the use, anti corrosion flanged globe valves include steam jacket, forged steel, oxygen use, bellows, and cryogenic type.
