YVUR-NPTF are non-return valves for in-line installation. The poppet is housed inside a valve body with NPTF-GAS female threads. The oil flow is free from port 2 to port 1 while it is interrupted in the opposite direction. The valve body, made of ASI316L stainless steel, makes YVUR valves suitable for applications operating in very corrosive environmental conditions. The remaining internal components are made of high-strength steel. Depending on the size chosen, the YVUR-NPTF valves can be installed in systems with flow rates up to 90 lpm (23,8 gpm) and maximum working pressures up to 400 bar (5800 PSI).
