The Series 8000 valve combines a bonnet design with a compact, field replaceable actuator to produce an air actuated fuel shut-off valve that's easy to install, operate and maintain. Quick exhaust and powerful closing spring combine to produce closing times of less than one second. The valve bon-net design eliminates packing adjustments to ensure reliable, safe closure. The valve is FM and CSA approved for fuel shut-off and its metal-to-metal seating design meets Class VI seat leakage standards. It also is approved for Class I, Div. 1 and Class I, Div. 2 hazardous locations.
