Can the Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR be installed to allow flow from A1 to A instead of A â A1?

No. The Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR is designed and specified for permissive flow direction A â A1; it will close and prevent flow in the opposite direction. Installing it to allow flow from A1 to A would reverse its intended function and is not acceptable unless the valve is specially modified or a different model specified for that flow direction is used.

Does the Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR use metal-to-metal sealing suitable for high-wear applications?

Yes. The Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR uses metal-to-metal sealing, which is specified in the description. Metal-to-metal sealing with a hardened steel stem and galvanized steel body is suitable for high-wear applications because it offers increased durability and resistance to abrasion and high temperatures (operating range â30Â°C to +100Â°C). Note that performance in a specific high-wear environment will also depend on fluid type, contamination levels, pressure cycles, and maintenance; consider these factors when selecting the valve.
