The three-position four-way valve, also known as the electromagnetic reversing valve, is specialized in the screw compressor unit.
The three-position four-way solenoid valve belongs to the fluid working system category, and includes four cut-off portions controlled by electromagnets mounted on the valve body, which are installed on the valve body in two groups, and the electromagnets on the same side of the valve body. The power supply is connected in parallel and turned on and off at the same time; each cut-off part is composed of a compression spring, a tapered valve core, a sealing gasket, a guide sleeve, a sealing ring, a nut, and a combined sealing gasket. The valve core has a through hole, the electromagnet is opposite to the tapered valve core, and the through hole communicates with the front cavity and the rear cavity; the front cavity of the cut-off portion 15 and the front cavity of the cut-off portion 9 share the A port, and the cut-off portion 15 The middle cavity passes through the D port, the middle cavity of the cut-off portion 9 passes through the C port, the middle cavity of the cut-off portion 14 and the middle cavity of the cut-off portion 11 share the B port, and the middle cavity of the cut-off portion 15 communicates with the front cavity of the cut-off portion 11 The middle cavity of the cut-off portion 9 communicates with the front cavity of the cut-off portion 14. The utility model has the advantages that it has no internal leakage problem, prolongs the service life, and is not restricted by pressure, and is suitable for gas and liquid control.

Three Way Plug Valve
The 3-way ball valve has particular structure and design of appropriative control system.It could be used widely in automatic controll systems and industrial sectors like metallurgy,mining, petroleum,chemical,electricity,light industy,watercraft and so on,matching with pneumatic control system.It is applicable to mixed or split stream project of different substance like fluid,gas or stive.We adopt dynamic balance four sides of seat sealed structure(Y type 3-way ball valve is three sides of seat sealed),this kind of structure make sure the good sealing:the slippery flow passage make the resistance of fluid to be weaker,and make the stream more smooth.The valve could be divided to L type and T type by the new open-back type of flow passage.The flange connection of valve could be designed accordding to the requirement of customer.

Brief introduction of pneumatic three-way ball valve: Pneumatic three-way ball valve is used for medium reversing, confluence and diversion in pipelines. It is mainly composed of T-type or L-type three-way ball valves connected with pneumatic actuators. According to different connection methods, it can be divided into flanges and internal threads. Pneumatic three-way. type ball valve is to switch or store the flow direction of two mutually perpendicular channels, and achieve the distribution function, while the T-type ball valve can not only switch the flow direction of the material, but also make the three channels Interconnect or close any one of the channels to play the role of diversion and confluence. According to the needs of T conditions, a valve positioner and other related accessories can be installed on the pneumatic one-pass valve liner to control the operation of the ball valve core. Achieve automatic control of the medium in the pipeline. Advantages of pneumatic three-way ball valve: 1. Different connection forms can be selected, which are divided into pneumatic flange three-way ball valve and pneumatic thread three-way ball valve to meet different working conditions. 2. Sealing effect, the elastic deformation of soft seal tetrafluoroethylene can achieve leak-free sealing. 3. One valve with multiple functions: it can be made into an L-shaped port or a T-shaped port to achieve functions such as distribution, confluence, and diversion. 4. The pneumatic three-way ball valve is easy to install, and any port can be used as the flow inlet of the medium, and there is no leakage 5. It is widely used in environmental protection, oil products, metallurgy, steam, energy, papermaking, food and other pipeline systems to change the flow direction of the medium or achieve the separation or mixing of the medium. Pneumatic three-way ball valve standard specification: 1.Design and manufacture: GB/T12237-1989; API608. 2.Inspection and test: GB/T13927-1992; API598. 3.Flange connection: JB/T79]-2-1994; ASME/ANSIB165. 4. Structure length: JD-2002 Response device: also called limit switch, remote feedback switch signal (explosion-proof) Solenoid valve: choose two-position five-way for double action, two-position three-way for single action (explosion-proof) Triple piece: It can stabilize the air source, filter, and add lubricating oil to the cylinder Valve positioner: Input 4~20mA signal to realize valve adjustment function YT-1000R
