Z41HChromium-molybdenum steelGate ValveOverview：

Z41HThe lifting and closing part of a gate valve is the gate plate, which moves perpendicular to the fluid direction. Gate valves can only be fully open or fully closed and are not suitable for regulation or throttling. The gate plate has two sealing surfaces. In the commonly used wedge gate valves, the two sealing surfaces form a wedge shape, with the wedge angle varying according to the valve parameters, usually...5oThe gate of a wedge gate valve can be made as a solid unit, known as a rigid gate plate; or it can be designed to undergo slight deformation, enhancing its workability and compensating for deviations in the sealing face angle during the manufacturing process. This type of gate plate is called an elastic gate plate. When the gate valve is closed, the sealing surface can be sealed solely by the medium pressure, meaning that the sealing surface of the gate plate is pressed against the valve seat on the other side by the medium pressure to ensure a seal, which is known as self-sealing. Most gate valves use forced sealing, meaning that when the valve is closed, external force is applied to forcibly press the gate plate against the valve seat to ensure the sealing integrity of the sealing surface. The gate plate of a gate valve moves in a straight line along with the valve stem, and this type of valve is called a lift stem gate valve.(Also known as a clear stem gate valve. Typically, the lifting rod features trapezoidal threads, which convert rotational motion into linear motion through the nut at the top of the valve and the guide slots on the valve body, thereby transforming the operating torque into thrust. In some valves, the nut of the valve rod is set on the gate plate. When the handwheel is rotated, it drives the valve rod to rotate, lifting the gate plate. Such valves are called rotating rod gate valves or hidden stem gate valves.

Z41HChromium-molybdenum steelGate ValveBoasts the following advantages:：

1Low fluid resistance, with minimal abrasion and erosion on the sealing surfaces.

2．Easier to open and close.

3Media flow is unrestricted, without disturbing the flow or reducing pressure.

4Simple in design, short in structure length, good in manufacturing process, and widely applicable. Gate valve types: They can be divided into wedge gate gate valves and parallel gate gate valves according to the sealing surface configuration. The wedge gate gate valves can further be categorized into single gate plate, double gate plate, and elastic gate plate types; while the parallel gate gate valves can be divided into single gate plate and double gate plate types. According to the position of the valve stem thread, they can be classified into exposed stem gate valves and concealed stem gate valves.
