Specifications
Spring Housing Materials: Ductile lron (standard) Contact Factory for other materials
Service: Steam, oil, gas, air, chemicals, and water
Shutoff: ANSI Class IV
Maximum Dome Loading Pressure: the combined pres sure of the spring setting (psig) and dome loading (psig) must not exceed the body rating.
Options:
- *C: Closing cap for adjusting screw
- B: Bleed valve on spring housing (available only with option C closing cap above)
- *CD: Closing cap/separated double diaphragm
- CDF: Closing cap/separated double diaphragm and flow thru dome
- CF: Closing cap/flow thru dome
- *H: Handwheel and packing box
- F: Flow-through spring housing. Permits “in-oil-line” installation for fuel oil atomization and steam atom- izing systems. Reduces the possibility of the oil asphalting on top of the diaphragm
- *D: Separated double diaphragm (prevents mixing fluids in case of ruptured diaphragm)
- DF: Double diaphragm/flow thru
- HP: High pressure spring housing
- H: Handwheel and packing box
- HF: Handwheel/flow thru dome
- HDF: Handwheel, double diaphragm/flow thru dome
* Available for Mark 63 and 64. Other options only available for Mark 63
* Low Flow Trim: reduced Cv’s (Kv’s) can be placed in any size valve as long as it is smaller than the standard Cv (Kv) for that particular size.
