What is the primary application for the Armstrong HLAR Series?

The Armstrong HLAR Series High Leverage Air/Gas Vents are designed specifically for venting gases from low specific gravity fluids at high pressures. They utilize forged steel bodies and very high leverage air relief mechanisms to handle these demanding conditions.

What are the maximum allowable pressure and temperature ratings for the HLAR Series?

The maximum allowable pressure for the HLAR Series reaches up to 3,700 psig at 100°F (255 bar at 38°C), specifically on the 26155G-HLAR model. Other models have varying limits, such as the 2313-HLAR which is rated for 1,000 psig at 100°F (69 bar at 38°C) and 600 psig at 750°F (41 bar at 400°C).

Can the HLAR Series air vents be used in sour gas service?

Yes, the forged steel and stainless steel traps can be modified to resist hydrogen sulfide stress corrosion for sour gas service. This modification involves annealing the float, which reduces the float's maximum working pressure to approximately half of its normal value.

What pipe connection types and configurations are available for these vents?

The HLAR Series vents are available with screwed, socketweld, or flanged connections. They can be configured with either two connections (Bottom Inlet - Top Outlet) or three connections (Side Inlet - Top Gas Outlet - Bottom Liquid Outlet).

What materials are used for the body and internals of the HLAR Series?

The standard bodies are constructed from ASTM A105 Forged Steel or ASTM A182 Grade F22 Forged Steel, depending on the model, with all-stainless steel internals including the valve, seat, leverage system, and float. Models 2313-HLAR, 2316-HLAR, 2413-HLAR, and 2415-HLAR are also available with cast T-316 stainless steel bodies.

What must be done to the float mechanism prior to installing the vent?

Before installing the liquid drainer/air vent, you must ensure the float is completely free to move. The float may be temporarily blocked with a fixing device, such as a rod, metal thread, or polystyrene, to prevent damage during transportation.

Which models offer the highest pressure ratings in the HLAR Series?

The highest pressure ratings are found in the 25133G-HLAR (2,120 psig max allowable pressure), 25155G-HLAR (2,520 psig), and 26155G-HLAR (3,700 psig) models. These specific high-pressure models utilize ASTM A182 Grade F22 Forged Steel bodies and spiral wound stainless steel non-asbestos gaskets.

Sour Gas Service

Forged steel and stainless steel traps can be modified to resist hydrogen sulfide stress corrosion. These modifications involve annealing the float, which will reduce the maximum working pressure of the float to about half its normal value. Consult Armstrong Application Engineering for allowable working pressures.

Important Note for Installation

The float might be blocked with a fixing device (rod, metal thread or polystyrene) to avoid damages during transportation. Make sure the float is free before installing the liquid drainer/air vent.

Connections and Installation

Armstrong Forged Steel High Leverage Ball Float Air/Gas Vents are available in two main configurations:

2 Connections: Bottom Inlet - Top Outlet
3 Connections: Side Inlet - Top Gas Outlet - Bottom Liquid Outlet

Possible connections include screwed, socketweld, or flanged. For models 2313-HLAR, 2314-HLAR, 2315-HLAR, and 2316-HLAR, only the bottom flange is machined directly into the air vent's body.

Remove float stop screw (16), if any.
Remove hex head screw (17).
Remove the valve seat (3) from the mechanism by folding back the lever (5) and unscrewing the valve seat clamp nut (18).
Replace the valve seat (3), place the mechanism and center it before tightening the clamp nut (18). Place the valve lever (5) back.
Center the valve lever (5) with the pivot clip and hold the valve firmly on the seat while tightening the hex head screw (17).
The float lever should remain parallel to the valve lever assembly (adjustment through the hex head nut (17)).
Replace float stop screw (16), if any.
Replace float (6) and float link (14) and assemble them with the pivot pin (15).
Replace gasket (7). Put the cap (1) back on the body (2) and screw bolts (10) and nuts (9).

Important Note: The type and material of bolts must not be changed.
