Q:What is the difference between Z41X gate valve and Z45X gate valve?

2 kinds of valve function, there is no difference.Nothing more than a one with a bright bar. One is a dark pole.Dark pole is cheaper.Everything else is the same. Contact me if you need another valve. Zhejiang Futai Valve Co., ltd.. The contact picture is in the head.

Q:What does valve qz45x - 10q mean?

Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure

Q:Function of gate valve

Valve strengths: (1) fluid resistance is small, due to the valve inside the valve channel is straight, and the medium flow through the valve does not change its direction of movement, so the fluid resistance is small. (2) the opening and closing moment is small, opening and closing more effort, as the gate valve opening and closing, the direction of movement of the gate and the direction of the media movement vertical, compared with the cut-off valve, valve opening and closing more effort. (3) the direction of the movement of the media is not limited, no disturbance, no pressure reduction, the media can flow in any direction from both sides of the gate valve, and all can achieve the purpose of use, more suitable for the direction of the movement of the medium may change in the pipeline. (4) the length of the structure is relatively short, because the gate of the gate valve is vertical inside the valve body, and the stop valve clack is horizontally placed in the valve body, so the length of the valve is shorter than the cut-off valve. (5) the sealing function is good, when the full opening, the sealing surface is less eroded. (6) when fully open, the sealing surface is less eroded by the working medium than the cut-off valve. (7) the shape is relatively simple, the forging technology is good, and the scope of application is wide.
