Armstrong

For low flows at pressures to 3,700 psi (255 bar) and specific gravity down to 0.40

The Armstrong high leverage series of liquid drain traps was developed especially for draining low-specific-gravity fluids from gases at high pressures. They use standard Armstrong forged steel bodies with very high leverage systems and spring assist.

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

It is essential that a safety factor of at least 2 be applied to the peak liquid load for sizing purposes. Do not use HLS drain traps on steam service.

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.
