Class 2500 Gate Valve

Class 2500 Gate Valve

A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The so-called Class 2500 gate valve is a gate valve that can stand ANSI class 2500. Class 2500 refers to the pressure/temperature rating of the valve. It means that the nominal pressure is from 42 MPA. It belongs to high nominal pressure.

Class 2500 gate valve has a full port design with OS&Y, outside screw and yoke and BB, pressure seat bonnet and rising stem. It has a fully guided and flexible wedge. The main parts of Class 2500 gate valves are one body, two seats, one wedge, one stem, one gasket, one bonnet, one back seat, several packing, one gland, one gland flange, one stem nut, two eye nut, two pins, two spilt pins, one name plate, one hand wheel, one stem nut and so on. As for the material of the parts, there are carbon steel, alloy steel stainless steel, brass and iron.

Class 2500 gate valve actually is a kind of gate valves. Therefore, it has the same features and working principle of gate valves. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. Class 2500 gate valve also has the distinct feature above-mentioned. Class 2500 gate valve is used for cut-off the medium, when full open the flow through the whole pipe, when the media running, there have a minimum of pressure loss. Class 2500 gate valve is usually used for the working environments which do not use frequently and keep the disc full-or full-closed. But it does not applicable to regulator or reducing the medium. When the flow of medium is high-speed, the disc to open at local conditions can cause the vibration of the disc, and the vibration damper may damage the disc.
