Complete Your Low-Temperature Installation with Pre-Fabricated Valve Insulation & Jackets That Fit! EXTOL Proven Products Extol of Ohio, Inc., in business since 1962, has specialized in providing quality fabricated insulation systems for refrigeration processes common to the food and beverage industry. We use cellular, rigid materials to supply constant thermal performance plus moisture and corrosion resistance.

EXTOL Advantages

Our quality, precision cut 2-piece insulation valves fit the contour of the most complex valve shapes. This reduces installation time and saves you money. To provide a USDA accepted system for indoor insulation, we have teamed with PIC Plastics to provide heavy duty (.030″) white UVR PVC Valve covers to fit T-Shaped valves, Y-Shaped valves and Control Valves with Strainers. Colors are also available.

Meeting Demanding Deadlines

Through our continuing development efforts we now provide custom matching PVC, Metal or Fiba-Clad Covers for the non-standard shapes found with valves, valve groupings, Control valves with Strainers and for non-standard Y-Shapes for both indoor and outdoor roof applications.

Each pre-formed valve order is custom fabricated to meet your demanding project requirements and schedule. Experience Extol’s on-time performance!


Reduced Energy Expenditures

Un-insulated valves and flanges create excessive heat gains for your refrigerant piping. Extol’s Valve Insulation will equip your system with continuous process control.
