Valve abbreviations
Thread Content
Dear experts, due to the incomplete dataset I have access to, there are no explanations for each abbreviation on the first page; as a result, I am not sure about some of the descriptions. I hope you can provide guidance: First sheet: 1. BALL 150# RF 316SS BODY TRUNNION 316SS TRIM RPTFE SEAT FP FS LP HNDL OP PE SERV; 2. BALL 150# RF STD BORE CSBODY TRUNNION CR-CARBIDE COATED BALL AND SEAT FP FS LPGO CAT SER; 3. BALL 150# RF CS BODY FLOATING 316SS TRIM RPTFE SEAT RP FS SP HNDL OP. What I mainly don’t understand is what “FP” and “RP” refer to in these three items Does it refer to the flange type? Another one: 1, DN250 BALL VALVE; API Std 6D; ASTM A216GR.WCB; RTFE+304 SS; CL.600; FL/FB; RF; GO; What I mainly don’t understand is what “FL/FB” means Could FL refer to a flange, and does FB refer to the type of flange?
1. DN250 BALL VALVE; API Std 6D; ASTM A216GR.WCB; RTFE+304 SS; CL.600; FL/FB; RF; GO; What I mainly don’t understand is what “FL/FB” means Could FL refer to a flange, and does FB refer to the type of flange? Upon further thought, it doesn’t make sense either, as RF is used later to indicate the flange type. It also doesn’t seem reasonable if FB refers to a FLOATING BALL; why would a ball valve of DN250 use a floating ball?
1. I mainly can’t understand what “FP” and “RP” refer to in the above 3 points Does it refer to the flange type? FP: Full Port – full diameter; RP: Regular Port – regular diameter. FP and RP refer to the diameter of the valve, not the type of flange. 2. I mainly can’t understand what “FL/FB” means? Could FL refer to a flange, and does FB refer to the type of flange? FL: Flange. FB: Floating Ball. But as you said, floating ball valves of DN250 CL600 should not be used; therefore, I suspect there is an error here.
fp is the full bore, rp is the reduced bore
