LP Lined Pipe Insert Valve
Brand: Check-All Valve Manufacturing CompanyThe Lined Pipe Insert (LP) valve is designed to mate between two flanges on most lined pipe systems.
It provides the simplest and most economical way to install a check valve in a lined piping system. No gaskets are required; just spread the flanges, center the valve and bolt the flanges together.
LP 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. The LP valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
