Ball Valves

Ball Valves

Ball Valves

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

A350 LF2 is same material group 1.1 from ASME B16.34 and is low temp CS and otherwise similar properties and should be suitable.

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.
