Accept the fully connected MAC solenoid valve structure and perform element leakage sealing throughout the entire pressure range, making it easier for the pipeline 

system to perform ball cleaning and pipeline maintenance. Accept special molding process, lining the lining material on the inner wall of the valve housing, which can 

withstand the erosion of strong acid and alkali media. The valve structure consists of a full bore floating ball type (two-stage) and a full bore fixed ball type 

(three-stage), which are important for cutting off or connecting corrosive media in pipelines, and can be used for fluid adjustment and control.

The characteristic of MAC solenoid valve is that the valve seat sealing ring is composed of multiple layers of stainless steel sheets on both sides of a soft T-shaped 

sealing ring.

The sealing surface between the MAC solenoid valve plate and the valve seat is a slanted cone structure, and a heat-resistant and corrosion-resistant alloy material 

is welded on the slanted cone surface of the valve plate; The structure in which the spring fixed between the adjustment ring pressure plate and the adjustment 

bolt on the pressure plate are assembled together. This structure effectively compensates for the tolerance zone between the shaft sleeve and the valve body, as well 

as the elastic deformation of the valve stem under medium pressure, solving the sealing problem of the valve in the bi-directional exchange of medium transportation 

process.

The MAC electromagnetic receiver is composed of multiple layers of stainless steel sheets on both sides of a soft T-shaped sealing ring, which has the dual 

advantages of metal hard sealing and soft sealing. It has zero leakage sealing performance in both low and high temperature situations. The experiment proves 

that when the pool is in a positive flow state (the direction of medium flow is the same as the direction of butterfly plate rotation), the pressure on the sealing 

surface is generated by the torque of the transmission device and the effect of medium pressure on the valve plate. The tighter the compression between the 

inclined conical surface of the valve plate and the sealing surface of the valve seat when the positive medium pressure increases, the better the sealing effect.

MAC solenoid valve, as a component used to achieve on/off and flow control of pipeline systems, has been widely used in many fields such as petroleum, chemical, 

metallurgy, hydropower, etc In the known butterfly valve technology, its sealing form mostly accepts sealing structure, and the sealing material is rubber, 

polytetrafluoroethylene, etc. Due to structural limitations, it is not suitable for industries that are resistant to high temperatures, high pressures, corrosion, and wear. 

The existing comparative butterfly valve is a three eccentric metal hard seal butterfly valve, with the valve body and valve seat as integrated components, and the 

sealing surface layer of the valve seat is welded with heat-resistant and corrosion-resistant alloy material

Connected together, an electric valve is formed through installation and debugging, and electric energy is used as power to connect the valve driven by the electric 

actuator, achieving the purpose of opening and adjusting the valve, as well as the purpose of opening and adjusting the pipeline medium. Electromagnetic valve is a 

type of electric valve that uses the magnetic field generated by the electromagnetic coil to pull the valve core, changing the coil of the valve body to cut off power 

and the valve core to switch on and off, relying on the pressure of the spring to retract.

It can be used for analog adjustment of medium flow in liquid, gas, and air system pipelines. In the control of large valves and air systems, electric valves can also be 

used as two position switches. Electric valve: It can have AI feedback signals, which can be grasped by DO or AO, and is more commonly seen in large pipelines and 

air valves.

The MAC solenoid valve housing is precision cast by investment casting, with high strength and smooth appearance. The parts in contact with the liquid are all 

fluoroplastics, so it can be used within the range of -50 to 180. It can work in corrosive pipelines and pipelines of any concentration. The electric fluorine lined ball 

valve can also be divided into two-piece and three piece structural types, with low fluid resistance, fast opening and closing speed, and simple structure. In addition, 

the ball valve with FEP lining layer has chemical stability and can be used for any strong corrosive properties except for "molten alkali metals and elemental fluorine". 

It accepts full bore and floating ball structure, and the valve can be closed without leakage in the entire pressure range, which is more convenient for ball passing, line 

sweeping and pipeline maintenance of the pipeline system. Ball parts and valve stem casting (forging) As a whole, the possibility of the valve stem bursting out of the 

pressure bearing part due to pressure changes fundamentally ensures the safety of use in engineering.

The action force distance of MAC solenoid valve is larger than that of pneumatic valve, and the opening and closing speed of electric valve can be adjusted. The 

structure is simple and easy to maintain. During the action process, due to the buffering characteristics of the gas itself, it is not easy to get stuck or damaged. 

It must have a gas source, and its control system is also simpler than that of electric valve. Pneumatic valves have sensitive response, are safe and reliable.

 Many factories with high requirements for control have set up compressed air stations specifically for pneumatic instrument control components. Electric means 

electricity. And a device that can grasp its flow rate.

Simply put, MAC solenoid valve is a valve controlled by an electric actuator to open and close the valve. It can be divided into two parts, the upper part is the 

electric actuator and the lower part is the valve. There are two types of MAC solenoid valves, one is the angular stroke electric valve: it is used by the angular 

stroke electric actuator in cooperation with the angular stroke valve to achieve a 90 degree rotation of the valve to control the fluid flow in the pipeline; 

Another type is the straight stroke electric valve: it is used in conjunction with a straight stroke electric actuator to achieve the up and down movement of the 

valve plate and control the flow of the pipeline fluid. It is generally used in equipment with a high degree of automation.

Internal leakage is usually caused by damage to the sealing surface of the valve seat or valve core. This can be done by grinding the sealing surface of the valve 

seat or valve core, but there is also a special situation where the valve stroke may not be set properly if it is electric or pneumatic. External leakage depends on 

where it leaks. If the valve body leaks, it can only be replaced.

If there is internal leakage, it should be due to the disappearance of the sealing surface. Please treat the sealing surface and see the effect.

External leakage can be easily handled. For the Sino French flange leakage, tighten the bolts of the middle flange again. If it still doesn't work, open and check if 

the gasket of the middle flange is damaged. For the leakage at the packing point, press the packing cover tightly. If the packing is too loose, add more packing. 

If it leaks directly on the body, it can be welded at low pressure. If it is high pressure, give up directly. It is safe. For internal leakage problems, it is difficult to 

determine the situation, and it may not be closed tightly. Close it again with force. Secondly, if the valve seat seal is damaged, it needs to be re ground. For valve 

core damage, it depends on whether the fluorine lined globe valve is damaged by flushing or by medium impact, but both need to be re welded with sealing surfaces.
