3 way 4 way ball valve

3 way ball valve introduction

3 way ball valve has L port, T port and Y type structure, which can meet the requirements of different production process.3 way ball valve has three entrances and exits, which are connected with three pipes for the merging, diverging and reversing of fluids.According to the operation,pneumatic and electric 3 way ball valve is optional.3 way ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline.3 way ball valve is widely used in petroleum, chemical industry, urban water supply and drainage and other conditions requiring strict cut-off. 
 
L port 3 way ball valve can switch the medium flow direction in two of the three pipelines, and also connect or close the two channels that are perpendicular to each other;T port 3 way ball valve can not only realize the switch of medium flow direction, but also make the three channels connected to each other, at the same time, it can also close any channel, make the other two channels connected, flexible control of the confluence or diversion of the pipeline intermediary;Y type 3 way ball valve has a mutual Angle of 120° and 135°, according to the need to achieve the medium flow direction switch, it is perpendicular to the two channels tee ball valve flow resistance is smaller.

3 way ball valve classification

L port 3 way ball valve
Under certain operating conditions, L port 3 way ball valve is adopted to improve the flow switch, and L port 3 way ball valve is used to cut off three pipe, L port 3 way ball valve adopts three seat structure design, also can use four seat structure design, using large sphere design,The 3 way ball valve not only has the flow switching function of ordinary L port 3 way ball valve, but also has the function of sealing and cutting off the three-way at the same time.
 
T port 3 way ball valve
There is no difference between T port 3 way ball valve and L port 3 way ball valve appearance, but the structure of the valve body spool is different.The T port 3 way ball valve can make the three orthogonal pipelines connect with each other and block the third channel, playing the role of diversion and confluence.L port 3 way ball valve can only connect two orthogonal pipelines, and cannot maintain the interconnection of the third pipeline at the same time, and only plays the role of distribution.
T port ball valve can replace the L port ball valve.L port 3 way ball valve is used to switch the flow direction of the medium, which can connect the two channels perpendicular to each other.
T port 3 way ball valve can not only realize the switch of medium flow direction, but also make the three channels connected to each other, at the same time can also close any channel, make the other two channels connected, flexible control of the confluence or diversion of the pipeline intermediary.
 
Y type 3 way ball valve
Y type 3 way ball valve is 120 degree or 135 degree structure,which can be equipped with manual, worm wheel, pneumatic, electric, hydraulic drive control. Y type 3 way ball valve 120 degree Angle,135 degree Angle) divided into 120° and 135°body structure, Y type 3 way ball valve flow path is flat, small fluid resistance, strong flow capacity.When switching medium has no retention, it will not cause secondary pollution.Y type 3 way ball valve is widely used in powder conveying industry,which can be matched with electric actuators and pneumatic actuators for automatic control.
 
Pneumatic 3 way ball valve
Pneumatic 3 way ball valve is made up of angle stroke piston pneumatic actuator and 3 way ball valve,which can be equipped with valve positioner to input control signal (4-20MADC or 1-5VDC) air source to control the operation.Pneumatic 3 way ball valve can also be equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa air source to achieve switching operation, and send two pairs of passive contact signals indicating the switch of the valve. Pneumatic 3 way ball valve is suitable for switching medium flow direction and distributing or mixing medium in pipeline system of water supply, petrochemical, metallurgy, mining, light textile, energy, paper making, food and steel, etc.

4 way ball valve introduction

4 way ball valve is known as two-way four-way rotary valve, one valve can be a valve to achieve positive and negative water supply switch, every turn 90℃, water supply mode switch once, before the need for four valves, valve 1, 4 open, valve 2, 3 closed;When reverse water supply valve 2, 3 open, valve 1, 4 close, now use a four-way ball valve to replace, easy to operate.
4 way ball valve is suitable for circulation system of liquid, gas, slurry and solid particle medium.4 way ball valve is used to replace the working principle of the manifold and valve group, which simplifies the procedure, facilitates the operation, reduces the cost, facilitates the control and has good synchronization
 

4 way ball valve feature

1. Small fluid resistance: the ball and valve body connecting the pipe section is equal, and the ball channel is connected by an arc, the medium through the ball, fluid resistance is small.
2. Good sealing performance: 4 way ball valve seat is made of PTFE material with certain elastic deformation and high strength to achieve good sealing performance and ensure the stability of the valve.
3. Long service life: Austenitic stainless steel is used for the valve core and bare neck, PTFE is used for the valve seat, which can achieve good corrosion resistance and extend the service life of the valve.
 

4 way ball valve application

4 way ball valves can be used in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation system;In the production of chemical products, medicine and food;In hydroelectric, thermal and nuclear power generation systems;In the water and drainage, heating and gas supply systems of urban and industrial enterprises;In the drainage and irrigation system of farmland;4 way ball valve is an important mechanical product closely related to production construction, national defense construction and people's life.4 way ball valve is used in all kinds of pipeline systems to cut off or connect the medium flow, so that the medium is transported to each designated point in accordance with a predetermined program.
