Favorite

The Jamesbury Figure 1057 Automatic Safety Shut Off Valves are CSA (Canadian Standards Association) approved to meet American National Standards Institute and CSA International Standards Specification Z21.21/CSA 6.5 Automated Valves For Gas Appliances and CGA3.9-M94 Automated Safety Shut Off Gas Valves for providing protection against hazards during operation of fuel systems or fuel burning equipment.

The valves will operate quickly to isolate or vent upon loss of electrical signal, and operate to isolate or vent if the instrument air pressure is lost.
