The Betts EV46934ALTS is a 3-inch aluminum internal air-operated emergency valve with a 90-degree grooved elbow outlet.
The Betts internal air emergency valve meets HM183 requirements for an internal self-closing stop valve. The body is constructed of aluminum with a shear section satisfying 49CFR178.345-8 as tested per TTMA RP 84. The 1/8-inch NPT air inlet is designed to shear and close the valve in the event of an under-ride accident, and a fusible plug dumps air pressure if temperatures exceed 212F. The valve uses Teflon-encapsulated seals for broad chemical compatibility, with an internal air cylinder that saves exterior space for maximum piping clearance, and a stainless steel jackscrew allows manual operation if the air system fails. Maximum operating pressure is 25 psi with 80 psi line pressure and 35 psi with 100 psi line pressure.
