Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?

Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,

Q:How much is the 150LB of the valve?

150Lb=2.0MPa=20 kg.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.

Q:Pump, valve, these belong to the material?

The pump belongs to the equipment (electromechanical equipment), and the valve belongs to the pipeline material.

Q:What are the specifications of the valves PN25, DN50?

PN is the pressure. DN is caliber. In a nutshell, it's the valve of 25bar 50!

Q:I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?

Tiemuyu666, let's go inside and see if there's anything we need. For reference only

Q:Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!

A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!

Q:What valve is the FCV?

FCV is the control valve, you can adjust the valve opening according to the required flow.1, also known as the valve control valve, in the field of industrial automation and process control by adjusting the control unit outputs the control signal, the final control element with the power to change the media flow, pressure, temperature, level and other parameters. Generally composed of actuators and valves.2, according to the characteristics of the trip, the control valve can be divided into straight stroke and angular stroke. According to the power used by the executing agency, according to its function and characteristics are divided into linear characteristics, such as percentage characteristics and parabolic characteristics of the three. Control valve applies to air, water, steam, a variety of corrosive media, mud, oil and other media.

Q:What valve is the YQZ45X-16Q?

Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.

Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?

The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.

Q:What is the valve?

Is the switch, switch on the pipeline and can walk on water, air, oil and so on go. A lot of categories, you can control the on-off, control pressure safety valve, as well as a lot of filtering valves.
