Aqua Environment 1091 1091 Series Open/Close Valve Hand Operated 2-Way High FLow

The Model 1091 toggle valve is an open or shut valve for air or gas lines up to 6000 PSI. In the normal or relaxed position the valve is shut and the lever extends straight out. When the lever is tipped in any direction the valve opens. A variety of levers can be connected to the 1/4"-20 thread. Alternately, a flat bar could be attached to the toggle with a short bolt. In many cases the valve eliminates the need for snap action switches, solenoids, and other complicated devices to open or shut a line based on mechanical action. One typical application is to open a cylinder charging line only when a protective door is shut. Here the door would push against the toggle to open the valve. A maximum of 30 inch pounds is required to actuate the valve at rated pressure. For example, a six inch lever would require five pounds to operate. A one inch thread section is provided on both ends permitting a variety of ways to mount the valve.

Installation

Use a suitable pipe thread sealant such as teflon tape on inlet and outlet threads. Do not over torque. Moderate torque applied with a 6 or 8 inch wrench is ample. Use ample teflon tape - 3 or 4 turns not 1 or 2 turns on pipe threads. The inlet is the male thread and outlet is the female thread at the side of the valve. The one inch thread at the top or bottom of the valve can be used to mount the valve through a one inch hole in a panel or mounting plate provided by the user. The actuating lever for the 816 can either be the eye bolt provided or any other lever extending in any direction as required by the application. The lever is mounted to the toggle using the 1/4"-20 thread provided. The valve is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.

Maintenance and repair caution

As with any regulator or valve, particulates or moisture can plug or freeze the internal filter or valve seat. This can occur when up-stream dryers are not changed or remain unused for long periods allowing corrosion materials to accumulate. In critical applications where it is important not to lose flow, a larger particulate filter should be used upstream. The user should establish time intervals for changing the valve cartridge, filter and upstream dryers based on experience and service conditions.
