BG/BT pressure valve FAQ:

1. What is the BG/BT pressure valve ?

BG/BT Pressure Valve is a pilot‑operated hydraulic relief valve. BG version adopts ISO subplate mounting, while BT version is threaded pipe connection. It limits system maximum pressure and protects hydraulic components from overload damage. A remote control port is available for remote pressure unloading operation.

2. What makes the BG/BT pressure valve ?

It adopts reliable pilot‑operated structure with low pressure hysteresis, low vibration and quiet running. Two installation options: BG for subplate mounting and BT for threaded connection. Remote control port enables remote unloading function. Multiple pressure grades are optional. Hardened precision spool reduces internal leakage. Standard dimensions ensure good interchangeability for replacement.

3. What is the working pressure range of BG/BT  pressure valve ?

Its maximum working pressure reaches 250 bar. The adjustable pressure setting ranges from 5‑210 bar with multiple optional pressure grades. The remote control port can also bear 210 bar maximum pressure. The set relief pressure shall be higher than normal operating pressure of the hydraulic system.


4. Can BG/BT pressure valve replace other brands?

BG‑version follows ISO standard subplate mounting dimensions and BT‑version adopts threaded connection, they can substitute most pilot‑operated relief valves of other brands. Before replacement, please verify key parameters: working pressure, flow capacity, pressure grade, remote‑control port function and installation type. Customized solutions are available for special system requirements.

5. What is the Response / Switching frequency of BG/BT pressure valve ?

As pilot‑operated hydraulic relief valves, BG/BT series have typical pressure response time of 80‑150 ms. They are designed for static pressure‑limiting and overload protection instead of high‑frequency cyclic switching. Actual response performance is affected by system flow, oil viscosity and pipeline volume. Frequent fast pressure cycling is not recommended to avoid premature wear and pressure drift.

6. Do you provide OEM or customized services?

Yes, we support OEM and customized services for BG/BT pressure valve. Customizable options include pressure grades, seal materials, adjustment styles and port configurations. Please provide your detailed specifications or drawings for accurate quotation.

7. How can I get a quotation quickly

Please provide the following details:

  • Model or displacement

  • Working pressure

  • Speed

  • Quantity
    We will reply within 12 hours with a competitive quotation.
