Ball Valves
Ball Valves
(OP)
Got to clear this befoe I procure.
I asked for a quote on ball valves and got some following deviations.
Asked = 6" Reg Port Ball Valve (600# RF, Trunion Mounted, WCB Body & Ball/ENC Coating, Gear operator)
Deviation = Offering LF2 body (rest same)
Asked = 2" Reg Port Ball Valve (600# RF, Floating Ball, 1 or 2 pieces, WCB Body/316 SS Trim, Lever operator)
Deviation = Offering LCC body (rest same)
Asked = 1-1/2", 1", 3/4" Reg Port Ball Valve (2000# NPT, Floating Ball, 1 piece, WCB Body/316 SS Trim, Lever operator)
Deviation = Offering Barstock Ball (rest same)
Could anyone clarify the deviations.

RE: Ball Valves
A352 LCC is material group 1.2 from ASME B16.34 is low temp CS, has higher tensile/yield and otherwise similar properties with more weldability if I remember correctly again should be suitable.
Typically in client specs bar stock is prohibited although B16.34 does not specifically address, I would err on caution side, suprised they have not offered forgings for small bore particularly NPT.
