What is the standard cracking pressure of the Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR and are higher options (3, 6, 10 bar) available?

The standard cracking (opening) pressure of the Check valve for shutting off the flow of hydraulic fluid, galvanized steel, type FPR is 0.5 bar. Higher options of 3, 6 and 10 bar are also available.

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.
