| Griswold Controls Air Handling: “Precisely!” |
|
| IR-IS |
The IR-IS is a matched set composed of the Isolator "R" and the Isolator "S" Valves. The IR controls the flow on the return side, while the IS functions as a Y-strainer on the supply side. Because both valves feature integrated ball valves, complete isolation of the coil for removal or inspection is accomplished with a turn of two handles.

| IB-TY |
The Isolator "Y" is a supply-side automatic flow control valve with integrated isolation ball valve and Y-strainer. The Isolator "B" is a union ball valve. Together, they constitute a complete package, providing isolation to the coil for easy maintenance, a reliable automatic flow control, and a Y-strainer. This multi-function package means cost savings to you in both material and labor.
