12 ackflow Preventers Used on boiler feed lines to prevent boiler water from returning to the potable water system. oiler water may contain chemicals and bacteria that could contaminate the potable water system. Series 9 ual heck Valve with Intermediate tmospheric Vent Sizes: 2" M3 (5mm), 3 4" M2 (20mm) Series 9 is designed to protect drinking water supplies from dangerous crossconnections in accordance with national plumbing codes and water authority requirements for non-potable service applications for smaller supply lines such as laboratory equipment, processing tanks, sterilizers, and dairy equipment. It is ideally suited for boiler feed lines to prevent backflow when supply pressure falls below system pressure. Series 9 is suitable for use on hot or cold water and can be used under continuous pressure. It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing. secondary check valve utilizes a rubber disc-to-metal seating. In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system. onstruction is brass body with stainless steel working parts, integral strainer and durable rubber discs. Female union inlet and outlet connections. Sizes 2" (5mm) and 3 4" (20mm). rain is 2" (5mm) thread connection.

IMPORTNT This valve should only be used and properly installed so that spillage of water could not cause damage. To avoid water damage due to valve operation, a drain pipe must be installed. It should terminate approximate 2" (305mm) above a floor drain or through an air gap piped to a floor drain, or other suitable place of disposal. Under no circumstances, should the vent opening or drain line be plugged.

They are also used to prevent re-circulation of cold return water to the boiler to prevent condensation in the boiler. Series LF70 and LFL70 Hot Water Temperature ontrol Valves Sizes: 2" " LE FREE * Series LF70, LFL70 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. The LF70-M2 can be set to any temperature between 90 F and 60 F (60 F and 20 F for model LFL70-M2) with flow rates as low as 0.5 gpm and as high as 23 gpm (refer to capacity chart on the back). The superior flow characteristics of this valve provide accurate temperature control to the requirements of SSE 07** across the rated flow range. The LF70 and LFL70 feature Lead Free* construction to comply with Lead Free* installation requirements. 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 LF70-M2 and LFL70-M2 incorporate 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 (-PEX), Quick-onnect (-Q) or PV (-PV) connections.
