Product Overview | 1177E Cycle Valves
OPERATING INSTRUCTONS
INSTALLATION INSTRUCTIONS
Do not attempt to install, operate, or repair these devices without proper training in pneumatic systems and devices, unless under trained supervision. Compressed air systems contain high levels of stored energy. Do not attempt to connect, disconnect or repair this product when the system is under pressure. Always exhaust or drain the pressure from a system before performing any service work. Failure to do so can result in serious personal injury.
The 1177E Cycle Valve requires clean and dry air at 60 to 70 psi connected to the actuator inlet port. When the 1177E Valve is sup- plied with air, the actuator will drive the valve to the full open po- sition. When air is removed from the actuator, the valve will snap shut. An orange indicator on top of the actuator moves when the valve opens and when it closes for visual position indication.
MAINTENANCE INSTRUCTIONS
Piping:
The valve has a grease fitting on either end of the valve shaft. The valves are greased in the factory before shipment. Once every 3 months or as required grease the valve using a high temperature lubricant rated for 450°F.
The 1177E Cycle Valve must be mounted in the piping with the shaft in the horizontal position and in a location without excessive radiant heat on the actuator and switch. Locate the actuator so that it is visible to the operator. (DO NOT locate the actuator behind the pipework). The switch and actuator must be accessible for maintenance. Pipe the valves as close to the burner as possible, but not in an area with temperatures greater than 176°F. Check the actuator compressed air inlet port for the presence of the inlet snubber. The snubber has a 1⁄8 " fpt connection. The vent port should have a small filter.
Replace the small exhaust filter on the actuator port, as needed.
