ZDAOX43 rail plug valve
ZDAOX43 rail plug valve: profile close to the gate, and the use of flange connection, the valve plug internal rotation principle to achieve opening and closing. Reasonable design principle, simple, beautiful to meet market demand. It can be used to cut off or connect the pipeline medium on various working conditions such as oil, chemical, pharmaceutical, fertilizer, power industry and other working conditions with pressure level of 150 ~ 900Lb (1.6 ~ 32.0MPa) and working temperature of -29 ~ 150 ℃. Track plug valve works: When the rail plug valve is fully open, the passage of the plug valve body aligns to ensure the desired minimum pressure drop. Turn the handwheel stopper toward the direction of the valve , and at the same time drive the valve plate to rotate 90 degrees. When the handwheel continues to be rotated, the stopper will depress so that the valve opens to both sides, the valve plate will tightly press on the valve seat, So that the valve is closed; when the hand wheel to the opposite direction of rotation, the first plug to move upward, so that the valve seat in the separation, continue to turn the hand wheel, so that the plug valve plate rotated 90 degrees, and finally the stopper channel in the body channel Align, so that the valve is fully open state. Rail Plug Valve Features: â‘ rail plug valve in the process of opening the valve plate and seat in a state of disengagement, the process of switching zero friction, sealing surface will not wear. â‘¡ plug rotating flexible, but also to ensure that the inlet and outlet flange and the end of the seal, while sealing with a soft seal (Viton), the seal is through the seal around the valve to achieve. â‘¢ unique dovetail groove protection and fixed ring, so that the seal is closed at zero leakage. â‘£ wide range of media, regardless of the installation direction. No vibration, low noise.
