Honeywell V4055D User Manual

Introduction
The following curves relate gas flow through the V5055 Industrial Gas Valve to stem travel. These curves show
valve performance under American Gas Association standard conditions:
Specific gravity of gas
0.64
Temperature (Fahrenheit)
60.00 116 Cl
Inlet pressure (inches water)
2.00 [0.5 kPa1
Pressure drop across valve (inches water) 1.00 fO.25 kPa1
The flow is given in both cubic feet per hour (left side of graphs) [cubic metres per hour1 and percent of rated
flow (right side of graphs). Maximum stem travel is 1.05 inches 126.6 mm].
The V5055A Gas Valve is designed for ON-OFF service.
The V5055B Gas Valve has a characterized guide for use with LOW-HIGH or MODULATING actuators, or
with ON-OFF actuators to aid in smooth light off.
The
V5055C Gas Valve is designed for ON-OFF service. When used with the proper actuator, it meets Factory
Mutual requirements for valve closed indication and Underwriters Laboratories Inc. requirements for valve seal
overtravel interlock.
The
V5055D Gas Valve is designed for ON-OFF service in high pressure applications.
The V5055E Gas Valve is designed for ON-OFF service in high pressure applications. When used with the proper
actuator, it meets Factory Mutual requirements for valve closed indication and Underwriters Laboratories inc.
requirements for valve seal overtravel interlock.
