Gate valve product series Stainless steel Japanese standard flange gate valve Shoulong gate valve Stainless steel Japanese standard flange gate valve Introduction
The fluid resistance is small because the internal medium channel of the gate valve body is straight, and the medium does not change its flow direction when flowing through the gate valve, so the fluid resistance is small .
The opening and closing torque is small because the gate plate movement direction is perpendicular to the direction of medium flow when the gate valve opens and closes. Compared with the stop valve, the opening and closing of the gate valve requires less effort.
The flow direction of the medium is not restricted. The medium can flow in any direction from both sides of the gate valve to achieve the purpose of use. It is more suitable for pipelines where the flow direction of the medium may change.
The structural length is shorter because the gate plate of the gate valve is placed vertically in the valve body, while the disc of the stop valve is placed horizontally in the valve body, so the structural length is shorter than that of the stop valve.
The sealing performance is good and the sealing surface is less eroded when fully open.
The sealing surface is easily damaged. When opening and closing, the gate plate and the valve seat are in contact with each other, and there is relative friction between the two seals, which is easily damaged and affects the performance and service life of the seal.
The opening and idle time is long and the height is large. Because the gate valve must be fully open or fully closed when opening and closing, the gate plate has a large stroke and requires a certain space and high overall dimensions for opening.
There are many parts with complex structure, which makes manufacturing and maintenance more difficult and the cost is higher than that of stop valves.
