Gate valve application:

The opening and closing member of the gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of the fluid. As the cut-off medium, the whole flow is straight through when fully open, and the pressure loss of the medium operation is minimized. Gate valves are generally suitable for applications that do not require frequent opening and closing, but also maintain the shutter fully open or fully closed, and are not suitable for use as adjustment or throttling. The gate valve has small fluid resistance, applicable pressure and temperature range, unrestricted flow direction of the medium, and good sealing performance. It is widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking and other transportation pipelines to cut or circulate media.


Gate valve classification:

The types of gate valves 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 be further divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valves can be Divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: open gate valve and dark gate valve. This type of valve should generally be installed horizontally in the pipeline.
