6″ x 6″ Black Epoxy Coated 90 Degree Elbow – Flanged or Grooved Outlet – External Air
Betts 6” emergency valve meets HM183 requirements for an internal self-closing stop valve. Body is constructed of aluminum and incorporates a shear section that satisfies 49CFR178.345-8 tested per TTMA RP 84. The body, disc holder, and bonnet assembly come standard with a black epoxy-coat for added corrosion protection. The valve is available in a flanged or grooved outlet with available body configurations of straight, 90° elbow, or tee style. Valves are supplied with an external air cylinder with 1/8” NPT port for air connection and a fusible plug installed to dump air pressure if temperatures exceed 212°F. ŧŧ
The Maximum Operating Pressure is defined as the maximum tank pressure that valve can open against with 90 PSIG tank air pressure.
Maximum Operating Pressureŧ: 12 psi [.83 bar]
Valve MAWP: 25 psi [1.7 bar]
Minimum Bursting Pressure: 100 psi [6.9 bar]

| * Last letters of part number designate seal material. See material table below for seal options ŧ All valves are test values. Actual values may vary due to service conditions. ŧŧ Temperature Rating: Fusible plug melts at +212°F [100°C]. Valve working temp. is dependent on seal material. See table below. CAUTION: Valve must be properly installed and maintained. Never bottom load through emergency valve without first opening valve. Failure to do so may result in damage to the tank and/or valve. |
