DN80-300 Horizontal Hydraulic Cylinder Axial Clamping Valve Test Bench

Equipped with intelligent digital pressure control system and multiple hydraulic self-locking protection devices.Supports both high-pressure water and low-pressure gas as test media.Covers test diameter range 3″ to 12″.Ensures uniform force distribution and stable pressure holding under high-pressure conditions.Compliant with GB/T 13927 and API 598 industry test standards.Meets stringent factory inspection requirements for high-pressure valves.

Detailed Product Description Brief Points

1.DN80-300 Horizontal Hydraulic Cylinder Axial Clamping Valve Test Bench is suitable for flanged, welded, and threaded end connections, including gate, globe, check, ball, plug, and other industrial valves.

2.Clamping method: main hydraulic cylinder directly drives the sealing plate against the valve end face, achieving axial end-face sealing with minimal external force on the valve body.

3.Sealing between valve and sealing plate: end-face sealing with O-ring or flat gasket, allowing direct visual inspection of leakage points.

4.Heavy-Duty Horizontal Hydraulic Cylinder Axial Clamping Valve Test Bench supports water for hydrostatic and high-pressure seal tests, and low-pressure gas (air or nitrogen) for pneumatic tightness tests.

5.Completed test items: 1.5×PN hydrostatic shell test, 1.1×PN high-pressure water seal test, and low-pressure pneumatic tightness test.

6.Test diameter range: DN80 to DN300 (3″ to 12″), with flexible stroke adjustment for different valve body lengths.

7.Hydraulic system: integrated design combining mechanical, hydraulic, electrical, and media circulation systems.

8.Reinforced bed structure: heavy-duty frame ensures stability and long-term accuracy under high-pressure conditions.

9.Intelligent digital pressure control: digital display and electric pressure-holding system for accurate and stable pressure maintenance.

10.Multiple hydraulic self-locking protection devices: pressure interlock prevents cylinder loosening when the test cavity is pressurised.

11.Core advantage: extra-large axial clamping force up to 130 tons, ideal for high-pressure heavy-duty valves inpetrochemical, power, and oil-gas applications.
