What do the valve types LB, OS&Y, and FP for gate valves mean respectively? I know that OS&Y refers to a stem-type valve seat, and BB denotes a valve cover connected by bolts. So what kind of valve cover is LB? What does FP refer to again?

Isn’t LB a unit of pressure, pounds? And does FP mean full port?

Is LB a unit of pressure, meaning pounds? And does FP stand for full port, meaning full diameter?

LB extended valve cover – is this a low-temperature valve?
