Product Features
STAINLESS STEEL FLOAT AIR ELIMINATOR TRAP

INSTALLATION

The NST11A Series Floating Traps with Air Vent will remove air and other gases from vessels or piping systems without allowing the contained liquid to escape. The valve and seat assembly, inside the NST11A, are connected to a stainless steel float. When there is no liquid in the body of the

NST11A the float will be at the bottom and the valve is in open position, allowing air or other gases in the vessel or piping system to escape. When liquids enter the NST11A, the float will rise, forcing the valve plug into the valve seat, which closes the valve and prevents the liquids from escaping.

1.The NST11A must be properly sized and properly located in the system. The inlet piping should be the same size as the piping connection on the body, and a full port isolating valve should be installed before the air eliminator.

2.Do not exceed the maximum allowable pressures and temperatures noted on the label of the NST11A body. Also, check to see if the air eliminator has the proper maximum differential pressure for your particular application.

3.The NST11A should be located at the highest point in the system or vessel where air can collect. The air vent must be installed level, vertical, and with the inlet at the bottom. Make sure that the air eliminator is mounted in the proper direction, with the flow arrow on the body. This will allow the float mechanism to operate properly. Isolation valves should be installed for ease of maintenance.

4. We recommend piping the discharge to a safe visible point .

5.Adhere to good piping practices by properly cleaning all piping before installing the NST11A. Clean the pipes by flushing to remove loose dirt. A strainer in the line leading to the air eliminator is recommended .

6.The inlet and outlet piping should be the same size as the NST11A’s connections. Do not reduce the size of the inlet on light loads; however, smaller pipe or tubing may be used on the outlet. Keep the piping as short as possible, with a minimum of valves and fittings.

7.Install gate valves or full ported ball valves (Do Not Use Globe Valves) so the NST11A can be isolated from the system to permit servicing.

MAINTENANCE

The NST10A Series is a maintenance free valve, composed of corrosion resistant components. No need for gaskets or adjustments.
