Pressure Reducing Valves
Reducing valves fill the system to a preset pressure for optimum performance. Combination Dual Unit Valves include pressure reducing valve and relief valve. Features and Benefits: Fast fill feature reduces start-up time and labor. Low inlet pressure check valve help prevent loss of system pressure if the supply water drops below system pressure. Convenient cleanable strainer is designed to prevent dirt and sediment from entering the system.Union connection available with 1/2″ male NPT thread and 1/2″ female sweat tail-piece for fast, flexible system connection. Brass body construction is highly resistant to corrosion – ideal for water systems.
Series 100 Inline Booster Pumps
The industry standard circulator for decades, Series 100 is still the one by which most others are judged. With well over 10 million units installed, the Series 100 remains a leader in applications such as hydronic heating and domestic hot water circulation.
Series 100′s three-piece, oil lubricated design provides for easy field service with bearings, shaft and seal all housed in an assembly which can be easily repaired or replaced. The Series 100 oil lubricated motor is specifically designed for the Series 100, and its resilient mounting provides quiet, dependable service with minimum annual lubrication. UL and CSA listings are standard.
