What is the standard opening pressure and available optional settings for the Galvanized Steel Hydraulic Check Valve, Type FPR – Flow Shut-Off?

The Galvanized Steel Hydraulic Check Valve, Type FPR – Flow Shut-Off has a standard opening pressure of 0.5 bar. Optional opening pressure variants available are 3 bar, 6 bar, and 10 bar.

Can the Galvanized Steel Hydraulic Check Valve, Type FPR – Flow Shut-Off be installed in orientations other than A → A1 without affecting performance?

The Galvanized Steel Hydraulic Check Valve, Type FPR – Flow Shut-Off is designed and specified for flow direction A → A1. Installing it in any other orientation is not recommended because the valve’s internal geometry, sealing surfaces, and hardened stem are optimized for that specified flow path. Using a different orientation can compromise sealing performance, change opening behavior (including the calibrated opening pressure of 0.5 bar or optional 3, 6, 10 bar variants), increase wear, and reduce reliability across the rated temperature range (-30°C to +100°C). To ensure intended performance, durability, and safety, install the valve in the A → A1 orientation as specified.

Additional information

Material	CS – steel (cast iron)

The FPR type check valve ensures reliable control of hydraulic systems by blocking fluid flow in one direction while allowing unrestricted passage in the opposite, guaranteeing efficiency and safety in demanding applications. With a standard opening pressure of 0.5 bar and optional variants of 3, 6, or 10 bar, it offers flexibility to match diverse system requirements. Designed for flow direction A → A1, the valve is manufactured from durable galvanized steel with a hardened steel stem, ensuring long-lasting resistance to wear and corrosion. The robust metal-to-metal sealing provides dependable tightness even under challenging conditions, while the wide operating temperature range from -30°C to +100°C makes it suitable for use in various industrial environments. Engineered for performance and reliability, the FPR check valve is an excellent choice for professionals seeking a high-quality solution to optimize hydraulic flow control.
