Check valves are generally installed in the discharge pipeline of the pumping system to ensure that the pumped medium does not flow back. With so many check valves on the market, finding the right one for your application can be a challenge. Before you start shopping for check valves, make sure you know the answers to these five questions.
For more information, please visit SUPCON.
The intended use of the valve and the environment in which it will be used are critical in order to select the correct valve for your specific application. It is very common to install the wrong check valve in the piping system, and the check valve should generally be selected according to the size of the pipeline.
Know that the flow rate is the most important, in gallons per minute (GPM), gallons per hour (GPH), if your process flow is higher than 8 feet per second flow through the valve, there will be higher wear Rate. When the flow rate is higher than 8 feet per second, whether it is a rubber valve or a metal valve, wear will cause performance degradation. The faster the flow, the more wear on the check valve, resulting in reduced life. Knowing the flow rate can help you choose the best check valve for your specific requirements.
Knowing the inlet pressure will help determine which type of check valve you need. Do you need a "ball" style check valve? Do you need a "swing" check valve? Or do you need a silencer check valve? Or a flange check valve or a wafer check valve? Determining which check valve you need depends on the orientation of the check valve in the pump system.
Back pressure is the pressure difference between the inlet and outlet pressures. For example, a valve is installed at the end of a pipe that discharges fluid into a small bore. How high will the water be above the surface as the flow rises? Back pressure occurs when water rises above this valve. Therefore, according to your detailed use, you should know how much back pressure the check valve needs to accept.
If the valve is installed submerged in the medium, this means that there is always a back pressure on the valve. In this case, you need to pick a check valve that is intended for submerged conditions and is manufactured from the correct material. The mistake of putting the wrong check valve in the piping system is relatively common. If your check valves are having frequent problems, it may be the result of a poor selection. Before purchasing a check valve, please inform Vitoli Valve salesman of your working conditions and needs in detail, and then you can choose a more suitable valve!

The electric control valve is a power-operated device that regulates a streamlined flow of gases, steam, water, and oil. It is considered one of the most important components used in industries to regulate the flow of materials.
Read this guide to find detailed information about working, application, advantages, and electric control valve pricing.
Electric control valve works on the principle of electromagnetic induction. It has a solenoid valve which is an electric coil. In its central position, it has a plunger or ferromagnetic core. When the solenoid valve is at rest position, its plunger closes a small orifice. When it is working, an electric current passes through a coil that creates a magnetic field. This magnetic field creates a force in an upward direction. Hence, it opens the orifice. This opening allows the liquids and gases to pass through it&#;however, the direction of flow of materials and exerted force work in the opposite directions.
The flow of liquids and gases in an electric control valve depends on these two factors:
The orifice diameter plays a central role in maintaining a flow rate and maximum operating pressure. A small orifice diameter generates more pressure and a more speedy flow of materials through it. Hence, you can easily maintain pressure differences from 0 bars up to the maximum allowable pressure ranges.
The amount of electric force generated is directly proportional to the flow of materials through an orifice. Therefore, more magnetic force means a more steady flow of materials. However, a permanent magnet generates a stronger magnetic field than a regular coil.

The valve positioner is a device that converts electric control signal from a controller device into an air signal. Thus, it controls the position of the entire system.
An air set or regulator maintains an accurate pressure level to the positioner. It smoothly channelizes air in the valve.
An electric control valve is available in the following materials:
You can contact our production team members to customize the electric control valve in any material to meet your industrial requirements. The selection of material is made by analyzing your requirements and intended industrial applications. The critical working conditions also play a significant role in choosing the suitable material for manufacturing an electric control valve.

The features mentioned above of electric actuators make them reliable for different industries. All you need to monitor their performance to ensure the best results regularly.
Use a blind flange to blind the output of the control valve. Check the body rating of the control valve. Open the valve at the time of testing. Now perform the test.
The amount of total pressure that a body can withstand without leakage is called body rating.
You can efficiently perform flow tests to determine leakage and streamline the flow of materials through the electric control valve.
If you observe any leakage, identify damages in the trim, actuator, and valve stem system. Probably, when these devices fail to connect properly, leakage occurs. Repair these damages to maintain a steady flow of gases, liquids, and semi-solid materials.

Closely monitor these stages to troubleshoot the working condition of an electric control valve. If you cannot troubleshoot the root cause, contact our trusted team members to solve your problem in just a few minutes.
An electric control valve requires either 4-20 mA or 0-10 V DC signal input. The input of 4 mA or 0 V closes the valve. Similarly, the input of 20 mA or 10 V DC opens the valve. However, any signal in between these two situations corresponds to a proportional situation. These input signal modulations are according to the industrial requirements. Therefore, any change in the signal input can lead to drastic changes in the output of an electric control valve. Moreover, this input signal can also be modulated as per industrial requirements to maintain a steady flow of liquids and gases.

Electric control valve permits automatic, semi-automatic, and manual operations. These high-performance valves are suitable for high-speed opening and closing of valves. The torque of the motor or position of the valve operates the actuator of an electric control valve. Similarly, a limit switch automatically stops the fully closed or fully opened valve. The utility of all these functions depends on industrial requirements and installation facilities. Although electric actuators are expensive, it is reliable for critical applications. It is perfect for low ambient temperatures, freezing pneumatic supplying systems, large stem forces, and devices with no air supply.
In an electric control valve, an electric actuation technique is used. It is actually a solenoid actuator in the electromagnetic coil. The solenoid actuator energizes and creates a magnetic force. This magnetic force pulls the armature and connects to the armature. However, it is done according to the requirements of the system.
Additionally, an electric control valve is also operated manually. Operator and critical working conditions control it. It would help if you had pushbuttons, pedals, and panels to manually control electric actuators.
