Gate Valve

Main materials: CF8\CF8M \CF3, CF3M, WCB

Features:
* Temperature range: -40º C~180º C~280º C
* Suitable medium: water, oil, steam, nitric, acid, acetate acid and some corrosive liquids
* Face to face and end to end dimensions conform to ASME B 16.10 / BS 2080 / DIN
* End flange dimensions conform to ASME B 16.5 / API 605 / BS 3293 / DIN
* Butt weld end dimensions conform to ASME B 16.25
* Anti frictional ball bearings are provided in higher sizes and classes
* The strength of stem to stem to gate connection is stronger than the strength of the stem at the root of the operating thread
* All the valves provided with backseat arrangement
* Bi-directional shut-off
* Deep stuffing box
* Body ports are streamlined, permitting unobstructed flow, reduces turbulence, results  in lower pressure drop and lower erosion
* For low temperature and cryogenic services (cold box and non-cold box applications) extended bonnet as per SB 6364 available

Applications:
Gate valve is widely used in fluid-handing systems for flow control. Typical gate valves are designed to be fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.
