MIL-PRF-12125H
a. Apply a hydrostatic pressure of not less than 350 psi (2410 kPa) at 150±5 °F
(65 ±3 °C) to the valve with both ends blanked and the gate in the open position.
b. Relieve the pressure, close the gate and apply a hydrostatic pressure of not less than
200 psi (1380 kPa) at 150 ±5 °F (65 ±3ºC) to one side of the valve with the other side
open to the atmosphere.
c. Open the valve approximately halfway and lock the lever mechanism.
d. Unlock the lever mechanism and rapidly open and close the valve 10 times.
e. Relieve the pressure, disconnect the pressure line and attach it to the other side of the
valve.
f. Apply a hydrostatic pressure of not less than 200 psi (1380 kPa) at
150 ±5ºF (65 ±3ºC) to one side of the valve with the other side open to the
atmosphere. Nonconformance to 3.4 shall constitute failure of this test.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as
specified in the contract or order (see 6.2). When actual packaging of materiel is to be

Inventory Control Point s packaging activity within the Military Department or Defense Agency,
or within the Military Department s System Command. Packaging data retrieval is available
from the managing Military Department s or Defense Agency s automated packaging files, CD-
ROM products, or by contacting the responsible packaging activity.
