3.7.1.1
Open-closing time and regulation. The valve shall
meet the opening and closing time requirements, and shall regulate to
the pressure specified in the specification sheet, under the conditions
specified in the specification sheet, when tested in accordance with
4.5.1 and 4.5.3.
3.7.2
Duty cycles. The valve shall be capable of con-
tinuous duty cycles as specified in the specification sheet and over the
ambient temperature range specified therein.
Pressure drop. The valve pressure drop shall not
3.7.3
exceed that specified in the specification sheet when tested in accordance
with 4.6.17.
3.7.4
Leakage. Total leakage (internal plus external)
shall not exceed the limits specified in the specification sheet, when
subjected to the test specified in 4.5.4.
3.7.5
Proof and minimum burst pressure. The valve shall
meet the operational requirements of this specification and shall not be
damaged or permanently deformed after having been subjected to a proof
pressure equal to two times the maximum pressure specified in the specifica-
tion sheet applied at the inlet port with the valve in both the open and
closed positions and while at maximum temperatures. Minimum burst
pressure shall be 1-1/2 times the proof pressure.
