Automatic Safety Shutoff Valves
(V5055 / V5097 INDUSTRIAL GAS VALVES;
V4055, V4062, AND V9055 ACTUATORS)
APPLICATIONS
The Honeywell family of automatic safety shutoff valves
consists of several combinations of fluid power actuators with
V5055 / V5097 Industrial Gas Valves. While it is possible to
combine any V5055 / V5097 Valve with any V4055, V4062, or
V9055 Actuator, a limited range of combinations apply to the
applications most often used (see Fig. 1 and Table 1). These
valve/actuator combinations are used for large gas burners
that require tight closeoff and accurate control of large
amounts of fuel. The valve opens when the actuator is
energized, and closes to seal off against the rated close-off
pressure when power is removed. The actuator determines
the method of firing. A V4055 is used for On-Off firing, a
V4062 for Hi-Lo-Off firing, and a V9055 for Modulating firing.
The V4062 and V9055 Actuators are normally used with the
V5055 / V5097B Valve with characterized guide for accurate
control and repeatability of low-fire positions. Valve/actuator
combinations are available that provide proof-of-closure
switch with valve seal overtravel interlock. Note that high
pressure valves and actuators are normally used only for On-
Off firing.

a
Refer to Table 2 for actual pressure ratings of the various combinations of valves and actuators.
b
V5055F models meet EN161 leakage requirements.
c
Characterized guide provides a more linear relationship between stem travel and gas flow. Check Honeywell form 70-8311 to
verify that flow curve characteristics match application requirements.
d
Valve Seal Overtravel Interlock. Valve has two shutoff seals, actuator has a proof-of-closure switch.
e
V4055F, G models include switch for manual control.
f
These combinations have higher pressure ratings; see Table 2.
