1″ Tapered Seat Aluminum Emergency Valve – Manual – 90 Degree Elbow
The Betts 1” Water Drain Valve meets HM183 requirements for an internal self-closing stop valve and is ideal for use as a water drain/sampling valve. The valve is manually operated with use of a pull cable and offers a 1” NPT male threaded inlet and 1” or ¾” NPT female threaded outlet.
The shear section is located above both the pull lever and push stem connection point which assists in providing a cleaner separation in the event of an under-carriage impact. The valve meets the shear section requirements of 49CFR §178.345-8 and is tested per TTMA RP84.
The valve body and O-ring holder stem are constructed of lightweight anodized aluminum to maximize durability and corrosion resistance. The valve push stem is stainless steel and is supported by an oil impregnated bushing with FKM-BLT (Viton® B low temp) standard seals for compatibility with a wide range of products and temperatures. The simplistic design allows for easy tear-down and maintenance.
Valve MAWP: 35 psi [2.4bar]
Minimum Bursting Pressure: 140 psi [9.7 bar]
