The valve is for use in wet system risers, preaction system risers and wherever a check valve with a drain connection and gauge connections can be utilized. When used with a flow switch on wet pipe systems not requiring a mechanical alarm, the Easy Rise~ Swing Check Valve may replace an alarm check valve. 1-A Features 1. Ductile iron body for less weight and extra strength. 2. Rated to 250 psi (17.2 bar) water working pressure. 3. Rubber-faced clapper hinged to access cover for quick removal and easy servicing. All moving parts can be serviced without removing the valve from the installed position. 4. With the cover/clapper assembly removed, clapper rubber replacement requires removal of only one screw. 5. Valve housing tapped for inlet and outlet pressure gauges, and system main drain. 1-B Accessories 1. 250 PSI (17.2 bar) Trim Packages Trim Packages include: A. All necessary nipples and fittings B.
