Help: There are many types of valves in the piping diagram that I don’t understand, and they are only labeled in English. I have a question: What kind of valve is a Valve with blind? RAM Type Valve ? Is a Globe Valve actually a ball valve or a globe valve?
Globe Valve – Stop valve. Ball Valve: Ball Valve
A valve with blind refers to a valve equipped with a blind flange. A Globe Valve is a stop valve.
A globe valve is a type of valve in which the closing element (valve disc) moves along the center line of the valve seat. Stop valves are extremely common in use, but due to their high torque required for opening and closing as well as their relatively long structure, their nominal diameter is usually limited to below 250 mm; some versions can reach 400 mm, yet special attention must be paid to the inlet and outlet directions when selecting them. Generally, for globe valves with a diameter of 150 mm or less, the medium flows in from below the valve disc, whereas for globe valves with a diameter of 200 mm or more, the medium flows in from above the valve disc. This is due to the closing torque of the valve. To reduce the opening or closing torque, most globe valves with a diameter of 200 mm or more are equipped with internal or external bypass valves.
Valve with blind : Gate valve RAM Type Valve : Check valve Globe Valve: Ball valve
A globe valve is a sliding stem valve; it should be a straight-stroke valve. Globe valve with blind: a straight-stroke valve equipped with a blind flange. Ball valve is simply a ball valve
The valve up to which is a stop valve
Thank you all for your answers; many thanks. To summarize: Valve with blind: Valve/gate valve equipped with a blind flange. RAM Type Valve: Check valve. Globe Valve: Ball valve
