DIAPHRAGM VALVES
Straight Through - Body

 

Kim Valves provide a wide variety of body materials and linings (see chart below) to suit various applications ranging from lime dosing to slurry handling where abrasion is a problem.

Kim Valves 'ST' valve body construction offers many end connections to suit various international standards. Available in BSP / NPT thread DN8 - DN50 and flanged to suit ANSI 125 / 150, BSTD/E and other drilling patterns on request. Face to face standard dimension is offered as per BS5156 but also available in DIN & MSS as an option.

Straight Through body construction is generally used on line media which is either abrasive and / or has a high viscosity and solids content. Use an 'ST' style valve when the line media reaches 10% solids or greater. If less than 10% solids is evident and the velocity and viscosity is low see the 'WT' style valve section on previous page.

Request a 'ST' valve for these applications and alike;

  • Slurry isolation
  • Lime dosing
  • Abrasive media
  • High flow / low pressure drop applications
  • Non acidic services
