Y-type strainers, also known as pipeline filters, decontamination filters, or filter valves, are indispensable filtration devices in pipeline systems that transport media. They are typically installed at the inlet of pressure reducing valves, pressure relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the valves and equipment.…

Ball valve: It evolved from the plug valve. Its opening and closing part is a sphere. The sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with a V-shaped opening also has a good flow regulation function.…

The main factors that determine the controller action include: Location of flow control element: It is necessary to clarify whether the flow control valve is located on the input side or output side of the process. Fail-safe operation requirements: Does the process need to automatically take safety measures in the event of a fault. Valve action type: ATC (Air-to-Close): The valve opens when ther…

The working principle of the bellows can be clearly understood from the structural diagram: the valve stem runs through the bellows, the lower end of the bellows is welded to the valve stem, and the upper end is welded to the fixed plate. A through hole slightly larger than the diameter of the valve stem is set in the center of the fixed plate. During the valve installation process, the sealing ga…

A safety valve (SV) is a spring-loaded pressure relief device that is driven by the static pressure of the upstream medium and has the characteristic of opening quickly or "tripping". This type of valve is mainly used for compressible fluids, especially steam systems. According to the certification standards, safety valves can effectively protect equipment from damage under overpressure conditions…

A pilot-operated safety relief valve is a pressure control device in which the main relief component (main valve) is used in conjunction with a self-operated auxiliary pressure control device called a pilot valve, which controls the opening and closing of the main valve. Pilot-operated safety relief valves can be fast-acting or regulating, corresponding to pop-up pilot valves and regulating pilot …
