.jpg) | Flange Insert Valve - F1, F6, FP Flange Insert valves are the ultimate check valves in flanged systems. They provide the simplest most economical way to install check valves in a piping system, the valve body automatically positions the valve and holds it in place while bolts are being installed and tightened. All that is required is two gaskets in place of the one normally used in a flanged joint. Flange Insert valves are designed to fit between two mating ANSI flanges. The "Spring Housing" designated by the "A" dimension is designed to be inserted into the upstream pipe, thereby centering it in the pipe. Therefore, there must be clearance between the spring housing and the pipe or flange. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe or Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe or Class 600 flanges. Flange Insert valves can be used as check valves, low pressure relief valves, and vacuum breakers by simply using different spring settings. Available Materials: • 316 Stainless Steel (SS) • PVC (PV) • Alloy 20 (A2) • Alloy B (HB) • Brass (BR) • Alloy C-276 (HC) • Carbon Steel (CS) • MONEL® (MO) • PTFE (TF) • Titanium (TI) For a quote or to request additional information regarding our Check Valves, please contact us by clicking on Get A Quote below or contact us by phone at 515-224-2301.

.jpg) | BUTT WELD STYLE - B4 The Butt Weld (B4) check valve is a one piece body machined from bar stock, eliminating porosity concerns and providing uniform density for more consistent welds. Made to ASME/ANSI B16.25 for schedule 40 pipe, it carries rugged, dependable Check-All trim with a wide variety of seat materials and cracking pressures to choose from. Note: Please take precautionary measures when welding to prevent heat build-up and possible damage to the valve seat. Available Materials: • 316 Stainless Steel (SS) • Alloy B (HB) • Alloy 20 (A2) • Alloy C-276 (HC) • MONEL® (MO) • Carbon Steel (CS) Additional Info: http://www.checkall.com/valvestyles/B4/Butt_Weld.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) • Alloy 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 | ||||||||
.jpg) | Style CAV The CAV series of valves are not catalog items but rather are custom designed and tailored to meet customer specific connections or valve configurations. If you have a check valve application where our standard catalog items do not quite match what you are looking for, contact our sales department to discuss your specific needs. | ||||||||
