Aqua Environment 816-B 816 Series Open/Close Valve Hand Operated 6000 PSI 1/4" NPT Brass Wetted Surfaces

The Model 816 toggle valve is an open or shut (2 way) valve for air or gas lines up to 6000 PSI. When the lever is tipped in any direction the valve opens. A variety of levers can be connected to the 1/4"-20 thread. For example, using an eye bolt as shown, the valve could be operated by a lanyard. 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 using a one inch jam nut.

Features:

• Open/Close Valve
• Hand Operated
• Brass Wetted Surfaces

Typical Applications:

• Test panels where fast, accurate, hand control of pressure is desired
• Gas supply interlocks such as protective doors on charging stations
• Component testing
• Process industry control
• Charging stations where it is desirable to have the supply shutoff if operator releases control

Installation

Use pipe thread sealant 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 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 CUSTOMER SHOULD PROVIDE A STOP SUCH THAT THE TOGGLE IS NOT FORCED BEYOND IT'S FULL OPEN POSITION. The valve is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.

Maintenance

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.
