A flat gate valve is a sliding valve in which the closing members are parallel rams. The closing member may be a single shutter or a double shutter with a distracting mechanism therebetween. The pressing force of the shutter to the valve seat is controlled by the medium pressure acting on the floating shutter or the floating valve seat. In the case of a double gate flat gate valve, the expansion mechanism between the two shutters can supplement this pressing force.


Company Profiles:

Steel types Longzhu uses contain carbon steel, middle-low alloy steel, duplex stainless steel ASTM A995 4A/5A/6A, ASTM A351 CK3MCuN and ultralow temperature steel types with special uses; while cast irons cover alloy cast iron, high-chromium iron, etc.


Material selection

a. What is the corrosive environment? – Atmospheric, water, concentration of particular chemicals, chloride content, presence of acid.

b. What degree of forming is required to make the component? – Austenitic steels are the most formable of all the types being able to undergo a high degree of deep drawing or stretch forming. Generally, ferritic steels are not as formable but can still be capable of producing quite intricate shapes. Duplex, martensitic and PH grades are not particularly formable.

c. It must also be borne in mind that steel type alone is not the only factor in material selection. Surface finish is at least as important in many applications, particularly where there is a strong aesthetic component. Availability. There may be a perfectly correct technical choice of material which cannot be implemented because it is not available in the time required.
