What are the three types of swing check valves? A valve that opens and closes with the force of the medium flow to prevent the backflow of the medium is called a check valve. Check valves belong to the category of automatic valves. Mainly used in pipelines where the medium flows in one direction, allowing the medium to flow in only one direction to prevent accidents.…

This type of globe valve is designed in strict accordance with the ASMEB16.34 standard; the connection between the valve body and the bonnet, the installation of the stuffing box, the valve stem nut, and the upper seal are all designed in strict accordance with API600. The valve material selection fully complies with API600 requirements. The structural length conforms to ASMEB16.10; the flange con…

The silent check valve belongs to the automatic valve category. Its function is to prevent the backflow of the medium in the pipeline. It is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.…

Pneumatic double-seat control valve, as the name implies, has two valve cores and two valve seats in the valve body. It adopts a double-guide structure and is mainly composed of a multi-spring straight-stroke pneumatic actuator and a straight-through double-seat control valve body. The pneumatic double-seat control valve is generally used. Under the requirement of pressure compensation, the pressu…

The Y-type filter is mainly composed of a connecting pipe, a main pipe, a filter screen, a flange, a flange cover and a fastener. When the liquid enters the filter basket through the main pipe, the solid impurity particles are blocked in the filter blue, and the clean fluid passes through the filter basket and is discharged from the filter outlet.…

Electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve is energy-saving (only consumes electricity…

The structure of the thermal insulation valve insulation jacket is roughly the same, which is mainly composed of a thermal insulation layer and a thermal insulation shell. The thermal insulation layer is generally directly wrapped on the valve, and the thermal insulation shell is sleeved on the outer surface of the thermal insulation layer. The disadvantage is that the installation and disassembly…

Electric four-way ball valve is composed of angular stroke electric actuator and four-way ball valve. It is used in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation systems; ball valves are used in chemical products, medicine and food production; in hydropower, thermal power and nuclear power production systems.…
