FAQS

How many types of valves are there?

Valves are used in fluid or gaseous handling applications to start or stop the flow, regulate or throttle flow, prevent backflow, and relieve and control pressure. Below you can see the different types of available:
  • Valve gates.
  • Butterfly valves
  • Valve globes
  • Valves with needles.
  • Valve inspection
  • Piston
  • Plug
  • Sluice
  • Ball
  • Diaphragm
  • Knife Gate
  • Parallel Slide
  • Pinch

What is valve size?

The most common method for sizing a control valve is to calculate the flow coefficient, Cv, which measures the valve body and trim capacity. The number of gallons per minute (GPM) will pass through a valve with a pressure drop of 1 psi at 60 degrees Fahrenheit (15.5 degrees Celsius).

What is the connection method of valves?

Regardless of the pressure level or valve size, flanged connections are the most common method of connecting valves. Flanged, threaded, and welded end connections are the most common ways to connect valves to pipelines and fittings. Valve end connection selection for general service is a simple question of whether the selected end connection type is available for the required valve type.

What is the operation mode of the valve?

A handwheel attached to the valve stem or Yoke nut is rotated clockwise or counterclockwise to manually close or open a valve. This is how globe and gate valves are opened and closed. Automatic valves, such as safety valves, pressure-reducing valves, steam traps, check valves, and mechanical regulating valves, rely on the medium's energy to open and close the valve.

What are the applications of valves?

Different uses, different materials, and additional pressure and temperature conditions necessitate a wide range of valves and valve configurations to meet the needs of all services and conditions. Valves are used in fluid or gaseous handling applications to start or stop the flow, regulate or throttle flow, prevent backflow, and relieve and handle pressure.

What is the size and pressure of valves?

At 60 degrees Fahrenheit, how many gallons per minute (GPM) will pass through a valve with a pressure drop of 1 psi (15.5 degrees Celsius)? Almost every pneumatic and hydraulic system contain pressure-control valves. It helps with various tasks, including keeping system pressures below a set limit and maintaining a set pressure level in a circuit.

What is the material of valves?

The materials used to build valves do not have to be completely corrosion resistant to the process fluid, as long as the fluid can be contaminated! If the purity of the process fluid is critical, all materials in contact must be corrosion resistant. If a certain amount of contamination is acceptable, the valve materials may be attacked.
