Direct-acting Proportional Relief Valve DBETR-1X Detailed Introduction

I. Product Overview

The DBETR-1X is a direct-acting proportional relief valve, a critical control component in hydraulic systems. It continuously and proportionally regulates system pressure based on the magnitude of the input electrical signal, enabling precise pressure control. This valve plays a vital role in hydraulic systems by protecting against overload pressures and ensuring stable operation under varying working conditions.

II. Technical Features

1. Direct-Acting Design

• The DBETR-1X employs a direct-acting structure, meaning it is driven directly by electrical signals without intermediate hydraulic power transmission. This design ensures faster response times and higher control accuracy.

2. Proportional Control

• The valve adjusts outlet pressure proportionally to the input electrical signal. A stronger signal increases valve opening and outlet pressure, while a weaker signal reduces both. This proportional control characteristic allows it to adapt to complex hydraulic system requirements.

3. High Precision and Low Hysteresis

• Equipped with an inductive position sensor, the DBETR-1X continuously monitors spool position and corrects deviations from the command value through closed-loop control. This eliminates the impact of solenoid friction, resulting in minimal hysteresis and high repeatability.

4. Multiple Control Electronics Options

• To meet diverse user needs, the DBETR-1X offers various control electronics, including:

• Analog amplifier VT5003

• Digital amplifier VT-VRPD-1

• Modular analog amplifier VT11025These electronics provide stable and reliable electrical signal output, ensuring seamless integration with the valve.

5. Easy Installation and Maintenance

• The valve’s subplate mounting surface complies with DIN 24340 Type A and ISO 4401 standards, enabling straightforward installation in various hydraulic systems. Its compact design and lightweight construction also simplify routine maintenance.

III. Technical Specifications

• Nominal Size: 6 Series 1X

• Maximum Operating Pressure: 350 bar

• Electrical Connection: Component plug conforming to DIN 43650-AM2

• Control Electronics Supply Voltage: 24 VDC

• Seal Material:

• MNBR (for mineral oil HL, HLP per DIN 51524)

• VFKM (for higher pressure ratings)

IV. Applications

The DBETR-1X direct-acting proportional relief valve is widely used in hydraulic systems requiring precise pressure control, such as:

• Metallurgical Industry:

• In metallurgical production, hydraulic systems must withstand harsh conditions like high temperatures and pressures. The DBETR-1X provides stable and reliable pressure control to ensure proper operation of production equipment.

• Machine Tool Manufacturing:

• Machine tool hydraulic systems demand high-precision pressure control. The valve’s low hysteresis and high accuracy make it an ideal choice for this sector.

• Automation Equipment:

• In automated systems, hydraulic systems often need to integrate seamlessly with electrical control systems. The proportional control capability of the DBETR-1X enables easy alignment with electrical controls.
