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.…

The three-way ball valve is mainly used to block, distribute and change the flow direction of the medium in the pipeline. There are two types of three-way ball valves: T-type and L-type. The T-shape can interconnect three orthogonal pipes and block the third channel. …

The gate valve is an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be surfacing with metal materials to increase wear resista…

Pneumatic ball valves are widely used in petroleum, chemical plants, power generation, paper industry, nuclear energy, airlines, rockets and other units, and their daily life. Pneumatic ball valve is a kind of gate valve with pneumatic electric actuator, and the pneumatic electric actuator has a relatively fast speed and a faster switching speed, which is 0.05 seconds/time, so it is generally call…
