Imported electric three-way ball valve imported from Lovol Leo

Imported electric three-way ball valve imported from Lovol Leo
Brand introduction of electric three-way ball valve /  Brand introduction
Lovol group is the world's leading supplier of fluid control products and services
Its products are designed and manufactured for various industrial and general commercial applications
Since its establishment nearly a century ago, more than 300 dedicated engineers have continuously developed high-quality valves and accessories to meet different market needs
All products are operated under a strict quality system that meets the ISO9001 international standard
Leo products and distributors are distributed in 43 countries around the world

Product structure /  Product structure： 
The electric three-way ball valve can be L-shaped and T-shaped
The L-shaped three-way ball valve is used for the switching of medium flow direction, which can connect two mutually perpendicular channels; T-shaped three-way ball valve is used for medium diversion, confluence and flow direction switching
T-shaped tee can connect three channels to each other or two of them
Three way ball valve generally adopts two seat structure, or four seat structure according to user requirements

  Working principle /  Working principle：
Electric valve usually consists of electric actuator and valve
The electric valve uses electric energy as power to drive the valve through the electric actuator to realize the opening and closing action of the valve
So as to achieve the purpose of switching the pipeline medium
Solenoid valve is a kind of electric valve; The magnetic field generated by the electromagnetic coil is used to pull the valve core, so as to change the on-off of the valve body
When the coil is powered off, the valve core will return by the pressure of the spring

Key points of model selection /  Selection points：
The selection of electric ball valve mainly considers the following problems

1
Connection mode
There are threaded connection, flange connection, clamp connection, welding connection, clamp connection and ferrule connection

2 pressure of the medium used
Generally, floating ball electric ball valve is often used for medium and low pressure media, metal hard sealed electric ball valve can be used for high pressure, and fixed ball electric ball valve can be used for high pressure and large diameter

3 temperature of the medium used
Temperature ≤ At 150 ℃, the soft sealing electric ball valve with Teflon plastic valve seat is selected, ≤ At 300 ℃, the opposed polystyrene sealing ring valve seat can be selected
Metal hard sealed electric ball valve shall be selected when the temperature exceeds 300 ℃

4
Corrosivity of the medium used
304 stainless steel, 316 stainless steel, 316L stainless steel, UPVC Plastic, special alloy and other materials are selected according to the corrosion of process medium

5V electric ball valve has good regulating performance and large adjustable ratio
It can accept the dc4-20ma standard signal of the control system for proportional adjustment
When the process pipeline needs electric regulating ball valve, it can be selected preferentially, which is suitable for suspended particles and fibrous media

6
The optional voltage of electric ball valve is generally AC220V, AC380V, special voltage DC24V, etc
, which need to be explained when ordering

7
The electric ball valve is generally controlled by switch, and the feedback contact output is active output and passive output
There is also a continuous resistance output signal, which can distinguish the valve opening

8 the connection mode of ISO5211 high platform ball valve and electric actuator is preferred
Standardized installation, convenient maintenance in the future

When the medium temperature is high, the connecting bracket shall be lengthened appropriately to prevent the high temperature from reaching the electric actuator and affecting the service life

9 three way electric ball valve and four-way electric ball valve are mainly used to switch the flow direction of medium
Three way ball valves are divided into L-type and T-type
Four way ball valves are mainly adjacent 90 DEG; Pipeline reversing

Features /  Characteristics：
1
The electric three-way ball valve has compact structure, rapid opening and closing, smooth flow channel and small fluid resistance

2
The electric three-way ball valve has good sealing performance: it uses the elastic deformation of polytetrafluoroethylene, the material of four-sided valve seat, to realize leak free sealing

3
One valve of electric three-way ball valve is multi-purpose: any port can be used as an inlet without leakage
The three-way valve can be made into either L-shaped port or T-shaped port

4
The electric three-way ball valve is easy to maintain: after the pressure of the system is relieved, the inspection and maintenance can be carried out without removing the whole valve body

 
Installation and use /  Installation and operation：
1
Before use, pay attention to check whether the components are damaged during transportation, and then install them;
2
Please pay attention to whether the medium flow direction is correct during installation;
3
Please pay attention to whether the installation conditions meet the technical requirements (such as working pressure, temperature range, etc
), and then install and use;
4
Try to avoid using in vibration environment, and pay attention to anti freezing measures at low temperature;
5
For electric valves, check the coaxiality of the coupling, then connect the temporary power supply, check and adjust the limit device of the valve in the state of fully open and fully closed, and repeat the test for at least 3 times
The electric system should act reliably and have clear instructions
