Step 6: Main Gas Shut-Off Valve Train - Eclipse WX Series Manual

Step 6: Main Gas Shut-Off
Valve Train
Eclipse Winnox WX Series v1 Design Guide No. 111, 9/25/2008
Component Selection
Eclipse can help in the design of a main gas shut-off valve train
that satisfies the customer and complies with all local safety
standards and codes set by the authorities within that jurisdiction.
Contact Eclipse for further information.
Note:
Eclipse supports NFPA regulations (two gas shut-off
valves as a minimum standard for main gas shut-off
systems).
Fuel Flow Measurement
Eclipse requires a fuel flow measurement device . Eclipse
recommendations can be found in the appropriate Winnox
datasheet, series 111.
Valve Train Size
Fuel pressure supplied to the ratio regulator inlet must be within
the range specified on the Winnox datasheet, series 111. The
valve train should be sized sufficiently to provide the specified
pressure. A second main gas pressure regulator  immediately
upstream from the burner gas inlet might be necessary to maintain
inlet pressure to the burner.
