.jpg) | The Lined Pipe Insert requires no gaskets, just spread the flanges, center the valve and bolt the flanges together. Lined Pipe Insert valves are available in fluoropolymer (PTFE/FEP/PFA) and Alloy C-276 to satisfy the most demanding applications. The standard spring material is Alloy C-276. Other materials are available upon request. Additional Info: http://www.checkall.com/valvestyles/LPI/LPI.htm   | ||||||||
.jpg) | Wafer Insert Valve Style - WV The Wafer Insert (WV) valve is designed to fit between two mating ANSI flanges. Two gaskets are required, instead of the one normally used. The "drop in" valve body fits inside the bolt circle for quick installation and removal in rigid piping applications where the use of the F1, F6, or FP are not practical. Many valves in this series meet API 594 requirements. WV valves can be used as check valves, low pressure relief valves, and vacuum breakers by simply using deferent spring settings. Available Materials: • 316 Stainless Steel (SS) • Ally B (HB) • Alloy 20 (A2) • Alloy C-276 (HC) • Brass (BR) • MONEL® (MO) • Carbon Steel (CS) • Titanium (TI) Additional Info: http://www.checkall.com/valvestyles/WV/wv.htm | ||||||||
