Flomatic says its Flo-Trol valves provide consistent, reliable performance for a variety of applications, including groundwater heat pumps, low-yield water well tanks, tankless water heaters, water softeners, irrigation systems and UV filters. Recent additions to the flow regulator line include ⅜ inch through 3-inch models and standard flow range offerings from .19 to 120. With only one internal controlling mechanism — a Buna-N self-cleaning orifice — Flo-Trol flow regulators provide constant flow over a wide pressure range. www.flomatic.com
