stainless steel globe valve can also be a stainless steel flange valve, the valve with flange connection. Stainless steel valve belongs to the cut-off valve, the valve body 301, 304, 316 stainless steel, stainless steel Industrial Valves is widely used in chemical industry, ships, food machinery and other industries. According to the operation can be divided into: manual stainless steel valve, stainless steel electric Industrial Valves, pneumatic valve, stainless steel welding stainless steel globe valve, hydraulic stainless steel globe valve.

basic little knowledge on globe valves are as follows:

globe valve is a kind of stop Industrial Valves, cut-off valve belongs to compulsory sealed valve, the valve is closed, must be pressure on the disc, to force a sealing surface does not leak. When the medium from the disc below to the valve, the operating force to overcome resistance, is stem and packing friction with the thrust produced by medium pressure, close the valve force stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens.

manufacturing standards: China GB, the mechanical JB, chemical standards HG, API, ANSI, DIN, JIS, JPI, British standard BS production.

the valve body material: copper, cast iron, cast steel, carbon steel, WCB, WC6, WC9, 20 #, # 25, forged steel, A105, F11, making, stainless steel, 316 l, 304 l, 316, 304, chrome molybdenum steel, low temperature steel, titanium alloy steel, etc.

connection mode: internal thread, external thread, flange, welding, butt welding, socket welding, card sets, clamp.

work pressure 1. 0Mpa- 50. 0Mpa。 Working temperature: - 196℃- 650℃。

once stainless steel globe valve is fully open, it will no longer have a contact between the seat and clapper sealing surfaces, and thus its sealing surface mechanical wear and tear is small, because most of the cut-off valve seat and valve disc is easy to repair or replace the whole valve sealing components without removed from the pipeline, that for valves and pipeline welding into one occasion is very applicable. Flow direction of medium through the valve changed, so stop valve flow resistance was higher than that of other valves.
