Plug valve, a valve that uses a plug body with a through hole as the opening and closing component. The plug body rotates with the valve stem to achieve opening and closing action. A small plug valve without packing is also known as a "cock". The plug body of the plug valve is mostly a conical body (also known as a cylinder), which forms a sealing pair in conjunction with the conical hole surface ...

1. Introduction to Y-type Filter Y-type filters are an indispensable filtering device in pipeline systems that transport media. Y-type filters are usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the normal use of valves and equipment. The Y-type filter has the characteristics ...

The small hole floating ball valve has the function of automatically opening and closing pipelines to control water level. This valve is made of high-quality copper material, with a small size and easy installation, high sensitivity for use, low head loss, and no water hammer phenomenon. It can greatly improve the utilization rate of the water tower (pool). For new water towers (pools), due to the...

The regulating valve positioner is the main accessory of the pneumatic actuator, which is used in conjunction with the pneumatic actuator to improve the position accuracy of the valve, overcome the influence of stem friction and medium imbalance, and ensure that the valve is correctly positioned according to the signal from the regulator. Positioners are required in the following situations: 1. Wh...

Ball valve structure There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flo...

Pneumatic valve is an actuator that uses compressed air to drive and operate the valve. Its opening and closing speed is relatively fast, and it is commonly used for quick two position cut-off. It can also be used to regulate flow. Due to its main reliance on air source for operation, it has high practicality in flammable and explosive situations, and can be used to control gases, liquids, oil pro...

1. Pneumatic valve positioner ooster When the air capacity of the booster control valve is large or the pneumatic signal transmission distance is long, the use of the booster can improve the response speed. 6. Speed Controller Speed Controller is installed in the regulator signal and drive part between the device, so that the regulator signal delay. Can also be used to prevent water hammer phenome...
