DBET-6X/315YG24-8K4M DBET-6X/315YG24-8K4V DBET-6X/315YG24-8K4V-7 DBET-6X/315YG24K4M German made proportional pilot relief valve, original imported hydraulic valve from Rexroth
The DBET-6X series proportional relief valves are direct-acting electro-hydraulic valves designed for precise pressure control in industrial hydraulic systems. These valves enable continuous pressure adjustment via electrical input signals (0-10V or 4-20mA), providing reliable overload protection and dynamic pressure regulation. The series includes models with external pilot oil return (Y-suffix) and various control configurations to meet diverse application requirements.

The Y-suffix indicates external pilot oil return capability, which allows separate routing of pilot flow to the tank. This is essential in systems with high backpressure at the return port, as it ensures stable valve operation and precise pressure control regardless of return line pressure fluctuations.
Yes, models with -8K4 suffixes (such as -8K4M and -8K4V) require external proportional amplifiers for operation. These amplifiers convert command signals (0-10V or 4-20mA) into the appropriate solenoid current. Standard K4M models can operate with direct electrical inputs but may benefit from amplifiers for optimized performance.
The -7 suffix typically denotes a special variant or configuration, which may include different pressure settings, modified response characteristics, or custom features. For specific details about the -7 variant, please consult the product documentation or contact technical support.
The K4M configuration features standard manual adjustment without detent, while K4V includes a detent mechanism that maintains the pressure setting without continuous manual input. The K4V variant is particularly useful in applications requiring stable, repeatable pressure settings where operator attention may be intermittent.
Standard seals are NBR (K4M) or FKM (K4V). While FKM offers broader chemical resistance, compatibility with water-glycol (HFC) or other synthetic fluids should be verified. Alternative seal materials may be available upon request for special applications. Always confirm seal compatibility with the specific hydraulic fluid being used.
- Lead Time: Standard models typically ship within 2-4 weeks; custom configurations may require additional time
