|  MV Series | VF Series | MR Series | DSDL Series | TF Series | TT Series | NR Series | Royal MV Cryogenic | CKV Series |     CKV SERIES     Orton wafer check valves have been designed to control flow direction wherever it is necessary to have very small weights and dimensions, but high strength and little pressure drops. The design allows the disc to open at an angle of 50-60C. A larger opening is not necessary since this angle provides the greatest bore area. Each face of the body has one o-ring, which assures flange sealing and ease of valve installation. One additional o-ring assures perfect sealing between clapper and body.     PRODUCTION RANGE:     ND 1 1/2" - 40" ANSI Cl. 150 ND 2" - 12" ANSI Cl. 300 ND 2" - 12" ANSI Cl.600 ND 2" - 12" ANSI Cl. 900 ND 2" - 8" ANSI Cl.1500.     MATERIALS:     Carbon steel Stainless Steel Aluminium Bronze Duplex SuperDuplex LCB, LC3 Monel Hatselloy 254 SMO Inconnel Alloy 20 Titanium.   << return to products
