aThe equivalent lengths for removable insulating boxes of valves are calculated as per table a, line 4b. They are valid for single skin boxes made of two parts with fasteners. These equivalent lengths include the jacketing stops for piping on both valve sides. 等值长度为可移动的绝缘的箱阀门根据...
During the time that both valves are open, the pressure in the two sieve beds and on opposite sides of the drive cylinder equalize and a portion of the gas in the pressurized sieve bed and drive cylinder side is captured rather than being vented to ambient. System efficiency is increased ...

The cusps of semilunar valves are open and stretched during ventricular systole and closed during ventricular diastole to prevent regurgitation of the blood into the ventricle. Points to be noted: A. No chordae tendinae or papillary muscles are related to semilunar valves. The connection of the ...
The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load...
A metal butterfly valve operates in a resilient valve seat which is interposed as a gasket between the flanges of two pipe ends, the seat having portions which project radially outwardly beyond the pipe flanges and which have tapered sides to match the tapers of the pipe flanges. Semicircula...
