Rexroth HED30A 40 200 Pressure Relay High Precision Stability‌ New Original

Product Description:

Rexroth pressure relays (such as the HED8OA-20/350K14), as core components for hydraulic-to-electrical conversion, offer the following advantages, features, and precautions for use:

Advantages

‌High Precision and Stability‌: Rexroth pressure relays utilize a precision mechanical structure, offering a wide pressure regulation range (e.g., 350 bar), high sensitivity, short actuation times (fast rise/fall times), and high repeatability.

‌Reliability and Durability‌: Products undergo rigorous testing, and sealing materials (such as NBR/FKM) are suitable for various operating conditions. They withstand high temperatures and high pressures, ensuring a long service life.

‌Standardized Design‌: Electrical connections comply with DIN EN 175301-803, ensuring easy installation and strong compatibility.

‌Diverse Functions‌: They can be used for safety protection, pump start/stop control, and sequence control, including hydraulic cylinder pressure control and pump unloading protection.

‌Precautions for Use

‌Correct Installation Location‌: Install in locations with significant pressure fluctuations (e.g., in the oil inlet line). Avoid installation in the oil return line, which could result in activation failure. ‌

‌Regular Maintenance‌: Check key components such as seals and pressure taps to prevent oil leaks and pressure measurement errors. ‌

‌Matching‌: Select the model corresponding to the system pressure level (e.g., 350 bar corresponds to 350K) to avoid malfunctions due to pressure range mismatches. ‌

‌Environmental Compatibility‌: Special sealing materials (such as FKM) may be required for high-temperature or corrosive environments. ‌

It is recommended to prioritize genuine products to avoid performance instability due to component quality variations.
