Product Description:

Rexroth pressure relays, as hydraulic-to-electrical conversion components, boast high precision, high reliability, and long lifespan, making them widely used in industrial automation control systems. The following are their specific features and usage precautions:

Core Advantages

‌High Precision and Stability‌
Rexroth pressure relays utilize precision mechanical construction, offering a wide pressure range, high sensitivity, and repeatability within 0.5%. For example, the HED8OA-20/350K14 pressure relay features spring-adjustable pressure range and sensitivity for precise control.

‌Durability and Reliability‌
Products utilize high-quality materials (such as FKM seals) for excellent sealing performance and resistance to high-temperature and high-pressure environments. For example, the HED8OA-2X/100K14AS model features seal materials that can be selected based on the application environment to meet diverse operating requirements.

‌Flexibility and Compatibility‌
These relays support pipe installation, and their electrical connections comply with international standards such as DIN EN 175301-803, enabling seamless integration with a variety of control systems. For example, the HEDE10-3X/250/1/-G1-K35-0 model features a microswitch that quickly responds to system pressure changes.

Precautions for Use

Proper Installation and Maintenance
Ensure the relay is located where pressure changes are noticeable (such as the oil inlet). Avoid installing it in the oil return line, which could cause malfunction. During installation, ensure the pressure measuring hole is clean to prevent clogging and impacting pressure measurement accuracy.

Avoid Environmental Interference
Avoid use in high-temperature, corrosive, or vibrating environments. Install protective devices if necessary. For example, the HED8OA-2X/100K14AS model clearly indicates recommended seal material selection.

Regular Inspection and Maintenance
It is recommended to inspect the seal condition and electrical connection reliability every six months and replace any aging components promptly. If sluggish operation or oil leakage occurs, investigate the spring or seal.
