Gate Valve

An advanced gate valve is a shutoff valve that can be fully opened or fully closed by vertically lifting the gate. Its core function is to reliably cut off the flow of media in the pipeline. It is suitable for working conditions that require bidirectional sealing or frequent opening and closing. The gate valve's opening and closing parts are gates, which move perpendicular to the fluid flow direction. The gate is driven by the valve stem to move along the valve seat axis to form a linear opening and closing action. It has the characteristics of small fluid resistance, straight passage without obstruction, and stable sealing performance. Its sealing surface usually adopts a wedge structure. According to the gate type, it can be divided into rigid gate and elastic gate. The latter compensates for processing errors through micro-deformation to improve sealing reliability.

Zhongguan gate valves are widely used in the fields of petroleum, chemical, water conservancy, and electric power. They are especially suitable for the shutoff needs of large-diameter, high-pressure or particle-containing medium pipelines, but are not suitable for flow regulation. The material selection includes cast iron, stainless steel, alloy steel and special lining materials, which can adapt to complex environments such as corrosive and high temperatures.

According to the structure, it can be divided into open stem (exposed lifting stem) and concealed stem (built-in valve stem). The open stem is convenient for observing the opening and closing status, while the concealed stem saves installation space. Modern gate valves reduce impurity accumulation through the flat bottom valve seat design, and enhance durability through the overall rubber coating process. At the same time, it optimizes weight and maintenance convenience, becoming an indispensable basic control component in industrial piping systems.

Rising Stem Design Resilient Seat Gate Valve

Rising Stem Design Resilient Seat Gate Valve is a common type of valve widely used in pipeline systems for media such as water, steam, and oil. It has the characteristics of good sealing, intuitive operation, and easy maintenance. At the same time, the Rising Stem Design Resilient Seat Gate Valve is an industrial valve, and the opening and closing component of the soft seal gate valve is the gate plate. The direction of movement of the gate plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

BS5163 Standard Resilient Seat Gate Valve

BS5163 Standard Resilient Seat Gate Valve is BS 5163 in the British Standard Resilient Seated Gate Valve is a specification for resilient seated gate valves in the British Standard, applicable to water supply, drainage, and other general industrial systems。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 when the medium temperature is not high, it is 2 ° 52 '' ''. 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 process ability and compensate for the deviation of the sealing surface angle during the processing.
