The test bench adopts a pneumatic booster pressure system combined with a hydraulic clamping structure, allowing operators to precisely control both test pressure and clamping force. During calibration, the output pressure is regulated manually through a high-precision pressure regulating valve on the control cabinet, ensuring stable pressure buildup without fluctuation.
The adjustable clamping force is monitored through a dedicated pressure gauge, and a reference comparison table between pressure and clamping force assists operators in selecting the correct clamping setting based on valve diameter and calibration pressure. This structure improves operational safety while reducing the risk of valve deformation during testing.
