What is the standard cracking pressure and available options for the FPU Hydraulic System Throttling and Check Valve?

What is the standard cracking pressure and available options for the FPU Hydraulic System Throttling and Check Valve? The FPU Hydraulic System Throttling and Check Valve has a standard cracking (opening) pressure of 0.5 bar. Optional cracking pressure variants are available at 2.5 bar, 5 bar, and 10 bar.

How does the FPU Hydraulic System Throttling and Check Valve perform under extreme temperatures and which materials ensure its durability?

FPU Hydraulic System Throttling and Check Valve performs reliably across a wide span of operating temperatures, rated from −20°C to +90°C. Within this range the valve maintains free flow in the A→A1 direction and precise, adjustable throttling in the A1→A direction, with stable opening pressures of 0.5 bar (standard) and optional 2.5, 5, or 10 bar variants. Durability under extreme conditions is delivered by its construction: a galvanized carbon steel body provides corrosion resistance and mechanical strength; a robust steel spring and stem ensure consistent actuation and resistance to fatigue; and NBR (nitrile) seals deliver secure sealing performance and oil compatibility across the specified temperature band. The plastic adjustment knob offers user-friendly control without compromising integrity. Together, these materials and design choices ensure the valve resists wear, maintains calibration and sealing, and sustains safe operation in demanding industrial environments within the stated temperature limits.

Additional information

Material	CS – steel (cast iron)

The FPU type throttling and check valve is a reliable solution for hydraulic systems, designed to ensure free flow in one direction while enabling precise regulation in the opposite direction through an easy-to-use adjustment knob. With a standard opening pressure of 0.5 bar and optional variants of 2.5, 5, or 10 bar, it offers flexibility to match diverse application requirements. The valve allows unrestricted flow from A to A1, while the reverse direction from A1 to A is efficiently throttled, ensuring optimal system performance and control. Manufactured from durable carbon steel with a galvanized body, complemented by a robust steel spring and stem, and finished with a practical plastic knob, it guarantees long-lasting reliability even under demanding conditions. The NBR sealing ensures secure operation, while the wide operating temperature range from -20°C to +90°C makes it suitable for various industrial environments. This combination of durability, precision, and adaptability makes the FPU valve an excellent choice for enhancing efficiency and safety in hydraulic applications.
