Cole-Parmer Ball Valve (Item number 98514-01)

Which valves do you choose? With so many on the market, go through this list step by step to narrow your choices.

  1. What’s your application?  Read the description for each valve to see if a particular type will work with your application.
  2. What fluid type (liquid or gas) is compatible with valve materials? PTFE withstands many harsh or corrosive chemicals. For safety reasons, always use metal for pressurized gases.
  3. What is the temperature, pressure, and flow rate you will be using? Generally, metal can stand higher temperatures and pressures than plastic.
  4. How long do you plan on using the valve? Choose normally closed or normally open depending on the state the valve will be in most often. For solenoid valves, consider response time and length of time valve will be energized. Continuous (100%) duty solenoid valves are best for frequent on/off cycling.
  5. What are your maintenance requirements? Ball valves resist plugging and are easiest to service.
