Z41 stainless steel gate valve:

The opening and closing component of stainless steel gate valves is the gate, and the direction of movement of the gate is perpendicular to the direction of the fluid. Stainless steel gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.
The types of stainless steel gate valves can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration. Wedge gate valves can also be divided into single pole, double plate, and elastic gate valves; Parallel gate valves can be divided into single gate plate and double gate plate. According to the thread position of the valve stem, it can be divided into two types: rising stem stainless steel gate valves and hidden stem stainless steel gate valves.
