H284 and H5114 internal spring relief valves for Bulk Storage tanks can be used in the H500 Combo Joe relief valve manifold or as separate units. The valves are identical except for valve body materials. When used in ASME tanks, the valves have only the poppet and part of the body outside the tank. The adjusting screw and all other parts are inside the tank, safe from tampering.
 
Type H5114 internal spring relief valves can be used in the H500 Combo JoeTM relief valve manifold or as separate units on stationary tanks. The valve body material – Type H5114 of 316 Stainless steel Anhydrous Ammonia (NH3) or LP-Gas service. All other components are stainless steel, including a 300 Series Stainless steel spring for additional resistance to product contaminants. A thickly molded main seal improves service life and resistance to severe applications. Flow area is 3.20 sq. in. Standard product temperature rating is -20 to 160°F / -29 to 71°C.
 
When used in ASME tanks, internal spring relief valves have only the poppet and part of the body outside the tank. The adjusting screw and all other parts are inside the tank, safe from tampering. Field-Repairable valve seats allow for seat replacement without affecting relief setpoint. Standard setpoints listed with UL® for the TypeH5114 includes 250 and 265 psig / 17.2 and 18.3 bar. All set points between 100 and 400 psig / 6.9 and 27.6 bar are available with ASME approvals.
Outlet is 3 in. NPT for discharge stack connection. Type P104-24 pipe away adaptor (3 in. FNPT) is available for use with either valve. A 3-1/2 in. wrench can be used when installing or removing the valve. The drain deflector is furnished as standard on the Type H5114. The Type P299 Rain Cap ships standard with each valve.
