Manual globe valves can have equal-percentage, linear or quick-opening flow. Since flow characteristics determine the flow rate, the operator can roughly determine the flow rate by the linear position of the manual handwheel. Pressure. Globe valves can handle pressure limits from 1480 to 1500psi.
Sizes: 2″ – 18″. Classes: 150 – 2500. SCV VALVE manufactures superior cast body, bolted bonnet globe valves in a variety of materials, trims, packing types, sizes (2″ thru 18″) and pressure classes (150 thru 2500). The mechanical characteristics (moveable disc and stationary seat ring) make the SCV globe valve ideal for repeatable pipeline
The Cv value for gases can be found using the following formula: Where: Cv = Valve Flow Coefficient QG = Gas Flow in Standard Cubic Feet per Hour T = Absolute temperature in °R. (°F + 460) psia = Absolute pressure. This is psig (gage pressure) plus 14.7 (atmospheric pressure) S.G. = Specific Gravity of medium where air at 70°F and 14.7 psia = 1.0
