Aqua Environment 816-3-V 816 Series Open/Close Valve Air Operated 3-Way or Vented 1200 PSI 1/4" NPT

The 816-3 valve is similar to the older 816-1 valve except the -3 valve uses a larger control piston permitting the use of lower control pressure. The valve, when used with an inexpensive low pressure solenoid. can be used in place of expensive high pressure solenoids. The 816-3V is a 3 way valve. When control pressure is released the downstream pressure is vented off.

Features:

• Open/Close Valve
• Air Operated
• 3-way or Vented

Typical Applications:

• Gas supply interlocks such as protective doors on charging stations
• Component testing
• Process industry control

Installation

Use pipe thread sealant Teflon tape on inlet and outlet threads. Do not over torque. Moderately torque with a 6 or 8 inch wrench . Use ample Teflon tape. TO AVOID PREMATURE FAILURE OF STEM ITEM 4 AN ORIFICE IS REQUIRED AT THE CONTROL AIR PORT. A .047" (#56 DRILL) ORIFICE IS ADEQUATE HOWEVER A .025" ORIFICE INSURES MAXIMUM LIVE. IT IS IMPORTANT TO PLACE THE ORIFICE DIRECTLY ON THE 816 CONTROL PORT TO AVOID EXCESSIVE DEAD VOLUME. The .025" orifice causes about a 1/2 second delay between release of control pressure and venting of high pressure

The inlet is the male thread and outlet is the female thread at the side of the valve. The one inch thread at the 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. Actuating pressure for the valve can be any non-corrosive gas or liquid at any pressure between the minimum and maximum given above under specifications. Pressure must be relieved for the valve to shut. If an electric solenoid is used, use the three way type to relieve control pressure. The regulator 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 upstream 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.
