What Is a Three Way Ball Valve ?
Product description
3-way ball valve have characteristics of large circulation capacity, compact structure, good sealing performance, long life, etc., economical and practical, easy to maintain. It is widely used in petroleum, chemical, natural gas, electric power, metallurgy, food, pharmaceutical and other occasions with strict requirements. It can also be applied to water, steam, oil, liquefied gas, natural gas, coal gas and other media. In addition, special hardening treatment can be selected according to customer needs, suitable for -196 ~ 400 ℃ , providing safer and more extensive applications.
Features
1. The valve body adopts precision casting or forging,with compact structure and beautiful appearance. The spool and stem of the O-type three-way ball valve make a rotating movement. When the spool is turned, the spool and valve seat are always in close contact with each other, which has a strong shearing ability;
2. The valve seat can be designed to be Preload by cylindrical spring or butterfly spring, with automatic compensation, self-sealing and automatic pressure relief in the valve cavity, suitable for high temperature and high pressure occasions;
3. The rotating design of the valve ball can ensure the smooth operation of the valve ball and reduce the operating torque;
4. There are optional soft and hard seals, and the sealing surface can be hardened, suitable for a variety of working conditions;
5. The automatic pressure relief design of the valve middle cavity. When the medium temperature of the valve body cavity rises and causes abnormal pressure increase, it does not need to pass the safety valve, but can automatically relieve pressure only by the function of the valve seat, which improves the safety of the valve when conveying liquid medium. Sex
6. Emergency fat injection rescue, in some special occasions, due to foreign objects in the medium or fire caused by the accidental failure of the valve seat seal, the grease injection valve provides a quick connection with the grease injection gun, which is convenient and quick to inject the sealing grease into the valve seat sealing part To mitigate the leak;
7.Ball valve Antistatic design、Anti-flying design of valve stem；
8.The elongated stem design is suitable for low temperature applications;
9.Three-way ball valve Any port can be used as an inlet without leakage It can be made into L-port or T-port channels according to the working conditions, which makes installation more convenient；
10.Inspection and maintenance can be performed without removing the entire valve body after the system is relieved of pressure；
11.Three-way ball valves are divided into L-type and T-type. L-type is suitable for medium flow switching, which can connect two channels perpendicular to each other.
T-type is suitable for medium splitting, confluence or flow direction switching;
12.The two-seat sealed three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. It can switch the flow direction of the pipeline medium, and can also connect or close the two perpendicular channels;
13.The four-seat sealed three-way ball valve has a beautiful shape and reasonable structure, which can not only realize the switching of the medium flow direction, but also make the three channels communicate with each other, and flexibly control the merge or split flow of the medium in the pipeline；
14.Any port of the four-way ball valve can be used as an inlet without leakage, and can be made into various types of channels according to the working conditions,making the installation more convenient;
15.The four-seater sealed four-way ball valve has a beautiful shape and reasonable structure, which can not only realize the switching of the medium flow direction, but also make the four channels communicate with each other, and flexibly control the merge or split flow of the medium in the pipeline.
