Introduction
The following curves relate gas flow through the
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
Inlet pressure (inches water) 2.00
Pressure drop across valve (inches water) 1.00
The flow is given in both cubic feet per hour (left side of graphs) [cubic metres per
and percent of rated
flow (right side of graphs). Maximum stem travel is 1.05 inches
mm].
The
Gas Valve is designed for ON-OFF service.
The
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
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
Gas Valve is designed for ON-OFF service in high pressure applications.
The
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
interlock.
