WELCOME TO
GRISWOLD CONTROLS!

Celebrating over 55 years as the leader in flow control technology.


Griswold Controls has set the standard for innovative, reliable and quality products for HVAC and Irrigation applications.

Beginning with the original 100% stainless steel cartridge for automatic flow limiting control, Griswold Controls has been the leader in HVAC technology for flow control and the experts in irrigation applications. We offer a wide array of products including:

  • Automatic Flow Limiting Valves
  • Manual Balance Valves
  • 2 Way & 3 Way Actuated Ball Valves
  • Pressure Independent Valves
  • Coil Piping Packages

HIGHLIGHTS

We are excited to introduce the next phase in our Pressure Independent Product Line, the PIM™-A. The PIM-A joins the PIM product family as an adjustable pressure regulator that can maintain a constant pressure differential across ANYTHING!

Griswold Controls is excited to announce the launch of the QuickDisc™ manual balance valve. This valve combines a traditional venturi for flow measurement with a ceramic disc never before used in the HVAC market. Ceramic discs have been used for years in the plumbing industry and are a perfect option to replace the more expensive ball valve typically used in HVAC.

Please view this video which shows the disc’s movement and explains the benefits of the QuickDisc.

QuickDisc valves are available in 1/2” and 3/4” sizes, with or without unions. This product complements the current 1/2” to 18” QuickSet® manual balance valve offering.

Griswold Controls K Valve has been certified to meet various legal standards for lead free product.

Griswold Controls introduces Pinnacle Valve

Pinnacle Valve is a pressure independent actuated valve. This compact zone valve incorporates pressure independent technology to control the flow regardless of pressure fluctuations in the system. The Pinnacle’s higher close off pressures make it ideal for applications where traditional zone valves are prohibited.
