Manual valves, also called block valves, are operated manually with a lever or handwheel.  They are primarily on/off but some can accommodate simple throttling.  In addition to regular valve uses, manual valves allow you to isolate of part of a process for maintenance, like removing pipe or equipment downstream.  They can also be used to stop all flow in a line for an extended period of time.

Type of manual valves include:

  • Ball valves
  • Butterfly valves
  • Gate
  • Globe valves
  • Diaphragm

Like all valves, manual valve requirements vary greatly in the parameters that need to be considered when specifying a valve and unfortunately, no one valve can handle every application.  Considerations include type of material flowing through the pipe, pressure, temperature, cavitation, flashing, noise and emissions.

Cross Company has decades of experience in specifying the correct control valve for an application.  Our experts can choose from a variety of manufacturers that we represent, including Neles (formerly Jamesbury), Flo-tite, Adams Valves, Apollo, Max-Seal, Parker and Steriflow.  We take the time to learn about your application and what you’re trying to accomplish and then make a tailored recommendation for your particular need.

We’ve also got a range of articles on our website to help educate you on the different types of valves and their applications.  Check out our series Valves 101, Ball Valves and Butterfly Valves.  For more information on all types of valves, visit the Resources section of the site.
