Is the FPMU Hydraulic System Throttling and Check Valve adjustable for different opening pressures (0.5, 2.5, 5, 10 bar) without disassembly?

FPMU Hydraulic System Throttling and Check Valve Format: Yes — the valve’s throttling function is adjustable without disassembly. The flow from A1 → A is regulated via a rotating ring that allows on-site adjustment of the throttling. Opening pressure (cracking pressure) is set by the valve version: standard 0.5 bar, with optional fixed variants 2.5, 5, or 10 bar. These preset opening-pressure variants are selected at manufacture (not via the rotating ring), so to change between 0.5 / 2.5 / 5 / 10 bar you must replace the valve or the internal spring/insert designed for that setting. However, fine throttling of flow rate (not the preset cracking pressure) can be achieved in-service by rotating the adjustment ring without disassembly.

Does the FPMU Hydraulic System Throttling and Check Valve allow field adjustment of the throttling ring to change flow characteristics without removing the valve from the system?

Yes. The FPMU Hydraulic System Throttling and Check Valve allows field adjustment of the throttling ring to change flow characteristics without removing the valve from the system. The valve’s design features a rotating ring that provides in-line, adjustable throttling in the A1 → A direction, enabling flexible regulation to match system requirements while installed.

Additional information

Material	CS – steel (cast iron)

The FPMU throttling check valve is a robust and reliable solution designed for hydraulic systems, ensuring precise control of fluid flow and dependable performance under demanding conditions. It enables unrestricted flow in one direction (A → A1), while in the opposite direction (A1 → A) the flow is effectively throttled and adjusted through a rotating ring, allowing for flexible regulation tailored to system requirements. With a standard opening pressure of 0.5 bar and optional variants of 2.5, 5, or 10 bar, the valve offers versatility to suit diverse applications. Manufactured from durable galvanized steel with a hardened steel stem, it guarantees long service life and resistance to wear, while the NBR sealing ensures reliable tightness and protection against leakage. Designed to operate within a wide temperature range from -20°C to +90°C, this valve delivers consistent performance in various environments, making it an ideal choice for industries seeking efficiency, safety, and durability in hydraulic control solutions.
