product overview

Yi'erValve productionQ944/Q945 electric three-way ball valves can be divided into L-shaped and T-shaped. The L-shaped (GFQ44F) electric three-way ball valve is used for switching the flow direction of the medium, which can connect two perpendicular channels; Electric three-way ball valve T-shaped (GFQ45F) three-way ball valve is used for medium diversion, merging, and flow direction switching. Electric three-way ball valve T-shaped tee can connect three channels to each other or two channels to each other. Electric three-way ball valves generally adopt a two seat structure, but can also adopt a four seat structure according to user requirements.

Product Features

1The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable, plastic is widely used as the sealing surface material for ball valves, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to twist 90 ° from fully open to fully closed, making it convenient for long-distance control.
5. Easy to maintain, ball valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface during the process.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball twists 90 degrees, it should present a curved surface at both the inlet and outlet to intercept the flow.
8. Three way ball valve is a relatively new type of ball valve, which has some advantages exclusive to its own structure, such as frictionless switch, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Paired with a multi turn electric actuator, it can achieve precise and tight control of the medium. Widely applicable to harsh cutting off conditions such as oil, urban water supply and drainage.

9. The L-shaped three-way ball valve mainly functions to divert the medium, while the T-shaped three-way ball valve mainly functions to merge.

10. The use temperature of PPL sealed electric three-way ball valve is 250 ° C or below, occasionally higher than 250 ° C is fine, but it cannot be equal to or higher than 250 ° C for a long time, otherwise it is easy to cause damage and leakage of the sealing ring, greatly reducing the service life of the valve body.

11. The operating temperature of the hard sealed electric three-way ball valve is 425 ° C, and its seals are all made of metal seals, suitable for high-temperature working media. Its seals are wear-resistant, temperature resistant, and tightly closed, meeting the standard of no leakage. Its cost is much higher than that of soft sealed three-way ball valves

12. The electric actuator can be extended with a bracket of about 20 centimeters to avoid excessive pipeline temperature affecting the normal operation of the electric actuator

13. The electric actuator is an intelligent regulating type, controlled by 4-20mA signal, which can achieve temperature and flow control, and play a role in adjusting the valve body at any angle.
