Plug Valve
Special Features :
The oldest design of valve comprising of a body with a tapered, or less frequently, a parallel plug. Design variants include Non-lubricated, Fluoropolymer sleeved, Lubricated and Pressure balanced designs, principally designed for on/off isolation of fluids they have inherent quick opening flow characteristics similar to bail valves, although specially designed eccerstric plug designs may be used for flow control applications.
They can be automated by means of quarter-turn actuators
Teflon Lined Valves
Special Features :
Ball valves come in two basic designs: Floating Bail and Trunnion Mounted, with three basic construction variants: Three piece, End Entry and Top Entry with options of either full or reduced bore designs, Principally designed as an on/off isolation valve for a very wide range of temperatures and pressures they have inherent quick opening flow characteristics. Specially designed ball valves however, may offer good flow control capabilities at High Pressure. Ail ball valves offer compact actuation due to their rotary quarter-turn operation. Firesafe versions are available for use in the oil and petrochemical industries.
