The Resilient Seat Lubricated Plug Valves is of the "block" or complete shut-off type. It may be used for throttling where accurate adjustment is not necessary. But the primary service is positive open-close operation. Three basic parts comprise the lubricated plug valve: body, cover and plug. The plug is the only movable member. The valve is opened by rotation only, the plug turning on a lubricated seat. While the plug is available in cylindrical and tapered form, the later is generally preferred, because the tapered rotary principle results in quick and simple valve operation. The conical shape of the plug combines the tight fit advantage of wedge action with the sliding action of rotary movement. Rotation eliminates the need for raising and lowering a movable valve member, and protects seating surfaces from exposure to corrosive elements. » Design & Manufactured to API 599, ASME B16.34 or DIN3202 ◆ P.T Ratings to ASME B16.34 » Face to Face dimensions to ASME B16.10 ◆ Flanged Ends to ASME B16.5 » Butt-weld Ends to ASME B16.25 ◆ Threaded Ends to ASME B1.20.1 » Socket-weld Ends to ASME B16.11 ◆ Valves Marking to MSS SP-25 » Inspect & Tested to API 598 » Sizes Ranges from 1/2” thru 30” » Pressure Ratings from Class 150 to Class 2500, PN10 to PN420 » Ends Connections in Flanged R.F or RTJ, Threaded NPT, BSPT, Welded S.W, B.W and Grooved » Body Materials available in Cast or Forged Carbon Steel ASTM A216 WCB, WCC, ASTM A105N, Low Carbon Steel LCB, LCC, LF2, Alloy Steel WC6, WC9, F11, F22, Stainless Steel CF8, CF8M, CF3, CF3M, A182 F304, F304L, F316, F316L, Duplex & Super Duplex Steel A890 GR. 4A, 5A or F51, Special Materials in Monel, Alu.
