VAPOR RELIEF VALVES Vapor relief valves are safety valves designed to open when tank pres- sure rises above 250 PSI. Used on applicator, storage, and nurse tanks, they will protect tanks, piping or hose from excessive pressure caused by overfilling or fire. Relief valves should be replaced 5 years after the date of manufacture which is stamped on the valve. ¾ in. Vapor Relief Valve for Applicator Tanks Part No. A1301A 1-¼ in. Vapor relief valve for Storage Vessels Part No. A1310A RELIEF VALVES A1301A

HYDROSTATIC RELIEF VALVE Hydrostatic relief valves are designed to relieve liquid pressure in valves, hoses, or piping wherein liquid may be trapped. Pressure set at 375 PSI.

Note: All safety relief and hydrostatic relief valves must be changed five years after date of manufacture. ¼ in. Hydrostatic Relief Valve Part No. A1327

ANHYDROUS AMMONIA SUPPLIES RELIEF VALVE MANIFOLD The A1416 relief valve manifold is used on large NH3 tanks to al- low removal of a relief valve for inspection or replacement, without the need to evacuate the tank. Adequate relief protection is provided by the remaining relief valve in the manifold. Bleeder valves relieve vapor pressure under each relief valve after closing the manifold port, and each port can be closed separately, meeting code requirements.

RELIEF VALVE ADAPTER Relief valve adapters are used when the NH3 hose assembly remains on the toolbar instead of the nurse tank. Install the adapter between the NH3 quick coupler and the NH3 hose assembly. Install a ¼ inch hydrostatic relief valve (A400 or A1325) into the re-

lief valve adapter to provide vapor relief to the NH3 hose assembly in excessive pressure situations. 1 in. MNPT x 1 in. FNPT Part No. A2031 1-¼ in. MNPT x 1-¼ in. FNPT Part No. A2032
