Direct axial sealing is achieved via the upper pressure plate, and the O-ring end face sealing method offers easy operation and reliable leakage observation. Customizable pressure ratings from PN16 to PN750 meet diverse factory and workshop inspection requirements. This bench is the ideal choice for valve manufacturers, maintenance workshops, and third party testing agencies that need fast, accurate quality control for small diameter valves.
The Mini Compact Horizontal Hydraulic Top Pressure Valve Test Bench is specifically engineered for efficient and precise testing of small-diameter valves, combining reliable axial sealing, flexible media support, and comprehensive test coverage in a space-saving design.
This bench is suitable for straight-through flanged, welded, or butt-clamp ball valves, gate valves, globe valves, check valves, and other common types. For clamping, the horizontal top-pressure cylinder directly pushes against the valve end face to achieve axial sealing, while the end-face O-ring seal between the valve and the blind plate allows operators to visually observe any leakage with ease. The test media can be water or low-pressure gas from 4 to 7 bar (air or nitrogen). The bench performs three main test items: hydrostatic shell test at 1.5 times nominal pressure, high-pressure water seal test at 1.1 times nominal pressure, and low-pressure air seal test from 4 to 7 bar. Its testing range covers DN15 to DN65 (refer to the pressure test range table for details). The sealing disc diameter is adjustable from 100 to 600 mm to accommodate different flange outer diameters, and the internal distance between tie rods is 500 mm for convenient valve loading and unloading. The top pressure cylinder (piston rod) has a diameter of 125 mm (one unit), delivering a maximum clamping force of 35 tons. The overall dimensions are approximately 1750 mm by 1250 mm by 1750 mm.
In summary, the Mini Compact Horizontal Hydraulic Top Pressure Valve Test Bench is compact, easy to operate, and an ideal solution for valve manufacturers, repair shops, and third-party inspection organizations that require rapid and precise quality control for small-diameter valves

It is suitable for straight-through flanged, welded, or butt-clamp ball valves, gate valves, globe valves, check valves, and other common types with small diameters.
2. What is the diameter range of valves that can be tested?
The tested diameter range covers DN15 to DN65.
3. What test media are supported?
The bench can use either water (for high-pressure tests) or low-pressure gas from 4 to 7 bar (air or nitrogen).
4. What specific test items can it perform?
Three main tests:
Hydrostatic shell test at 1.5 times nominal pressure
High-pressure water seal test at 1.1 times nominal pressure
