HLAR Series High-Leverage Ball Float Type Air Relief Traps

Description

For low flows at pressures to 2,700 (186 bar) or specific gravity down to 0.49

Armstrong developed the high-leverage series of air-relief traps
especially for venting gases from low-specific- gravity fluids at high
pressures. They use standard Armstrong forged steel bodies with very
high leverage air-relief mechanisms. They are available with screwed,
socketweld or flanged connections.

NOTE: Models 2313-HLAR,
2316-HLAR, 2413-HLAR and 2415-HLAR are also available with cast T-316
stainless steel body and all-stainless steel internals. Consult factory.

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.
