10 utomatic ir Vent Valves Used on boiler piping to automatically and continuously vent air from the system water and prevent air collecting in system piping. Series FV-4M utomatic Vent-Valve Sizes: 8" " ( 25mm) NPTF Provides automatic air venting for hot or cold water distribution systems. Purges air that may be in the water system and utilizes a float to actuate the valve plug which is located at the top of the valve. Once the air is displaced and the system pressure is sustained, the valve plug seals and prevents any water from escaping the system. The float vent also operates as an anti-vacuum device since it will permit air to enter the system when it must be drained.

21 Thermostatic Mixing Valves Expansion Tanks Used on boiler supply lines to control the temperature of supply water to heating zones by mixing hot boiler water with cooler return water. They are used to provide control of tempered water to the domestic hot water system. They are also used to prevent re-circulation of cold return water to the boiler to prevent condensation in the boiler. Series 70-M2, L70-M2 SSE 07 Listed* Hot Water Temperature ontrol Valves Sizes: 2" " (5 25mm) Ideal for use at the hot water source to maintain and limit temperature in domestic systems. Series 70-M2, L70-M2 Hot Water Temperature ontrol Valves are specifically designed for mixing hot and cold water on hot water supply systems. They can be used for a variety of applications to reduce the temperature of the hot water from the system, and are ideal for radiant heat applications. This series features a double throttling design which combines the control of the hot and cold water to provide a sensitive response to changes in water temperature passing through the mixing chamber. These valves also provide additional safety as they restrict mixed water out to a drip upon loss of cold water supply to the valve. s an added feature, the 70-M2, L70-M2 series incorporates integral check valves and filter washers in both the hot and cold water inlets to protect against cross flow. vailable with threaded (-UT), solder (-US), PEX or PV connections.
