UNMARKED RHD35L Non-Return Valve

Description:

The UNMARKED RHD35L Non-Return Valve is used in hydraulic fluid systems to allow flow in one direction while preventing reverse flow in high-pressure tube fitting assemblies. Commonly installed in hydraulic power units, industrial machinery, mobile equipment, and fluid transfer systems. Maintenance teams and system integrators use this part for repair, retrofit, or replacement of check valves to maintain system pressure and protect hydraulic components.

Applications:

The UNMARKED RHD35L non-return valves are used in hydraulic systems requiring reliable backflow prevention and pressure retention. They are commonly found in hydraulic power units, machine tools, construction equipment, material handling systems, and industrial process machinery. The RHD35L design corresponds to a 24° flareless tube fitting style check valve with a 35 mm tube connection in the light-duty (L) series, providing dependable one-way flow control in hydraulic circuits operating up to 250 bar.
