The MHV-HD300/37.5-S integrates hydraulic system, electrical control system, high/low pressure water supply system, and test fixtures into one horizontal test station. The bench adopts a horizontal top-press structure, where the top-press cylinder applies stable clamping force directly onto the test fixture, ensuring reliable positioning and sealing conditions during pressurization.
The system uses end-face O-ring sealing between the valve and blind plate to meet standard sealing requirements. Test pressure is generated through a combined pressure supply approach: the low-pressure water pump provides initial pressurization, and the high-pressure water circuit works with a pneumatic drive source (4–7 bar) to reach the required high-pressure testing range.

Water Circuit and Pressure Supply Logic
- Low-pressure water filling: The low-pressure pump is a self-priming, high-flow filling pump with a full-load pressure of 0–1.6 MPa.
- High-pressure boosting: The high-pressure pump is driven by a 4–7 bar pneumatic system, with a pressure range of 1.6–40.0 MPa.
- No auto-stop: After reaching the required test pressure, the system does not stop automatically.
- Circulation & protection: A bottom circulation tank is equipped; rust inhibitor (powder) can be added to reduce corrosion of the tested valve and pipelines.
- Hold-time alarm: When the set pressure-holding time is reached, an audible and visual alarm is triggered.
