DN300 Full Vertical Hydraulic Axial Press Valve Test Bench

The DN300 Full Vertical Hydraulic Axial Press Valve Test Bench is specially engineered for shell strength and sealing performance testing of gate valves, ball valves, globe valves, check valves and strainers with flange, welded or threaded connections, and serves as core quality control equipment for valve factory outgoing inspection.

Dual clamping system for 3 connection types: Top Φ150mm thrust cylinder directly drives the sealing disc to realize axial end-face sealing, matched with 3 sets of bottom jaw clamping mechanisms. It is compatible with flanged, welded and threaded valves without replacing tooling, covering over 90% of common industrial valve specifications.

Visual end-face O-ring sealing: Adopts open end-face O-ring sealing structure for flanged valves. Leakage positions are clearly visible during the pressure holding process, helping inspectors quickly locate sealing defects and improve quality inspection efficiency by more than 30%.

Dual media full-range inspection: Supports high-pressure clean water for hydrostatic strength test and 4-7bar low-pressure gas for air tightness test. One machine completes 1.5 nominal pressure shell test, 1.1 nominal pressure high-pressure seal test and low-pressure air seal test, fully compliant with API 598 and GB/T 13927 international standards.

Integrated vertical compact structure: All-in-one machine design with independent centralized control cabinet, small floor area, 50 tons stable vertical clamping force, no displacement under high pressure. Built-in circulating water tank with rust inhibitor is suitable for long-term continuous operation in production workshops.

This vertical axial pressure hydraulic valve test bench has passed API, GB, ISO and CE certifications, and is fully compatible with GOST standard valve testing for Russian and Central Asian markets. If you are looking for a reliable multi-functional valve pressure testing equipment for your production line, or need custom configuration for special valve models, contact us to get the full technical datasheet and exclusive factory quotation within 24 hours.

Product Core Highlights

3-in-1 connection compatibility: One machine adapts to flange, welded and threaded valves, eliminating the need to purchase multiple dedicated testing equipment and reducing one-time equipment investment cost.

Open visual leak detection: End-face open sealing design, leakage points are visible at a glance, no need for disassembly and re-inspection, greatly shortening the defective product screening cycle.

Axial direct pressure technology: Top hydraulic cylinder directly drives axial sealing, uniform force on the valve end face, no eccentric wear of the sealing disc, and the service life of wearing parts is 40% longer than that of ordinary side-clamping models.

Overpressure automatic protection: When the test pressure reaches the set value, the pressurization system stops automatically, which prevents overpressure damage to the tested valve and ensures safe on-site operation.

Built-in circulating water system: Integrated water tank with rust inhibitor added, which avoids rust of valves and pipelines, water-saving and environmental protection, suitable for 24-hour continuous batch testing.

Core Technical Advantages

The DN300 Full Vertical Hydraulic Axial Press Valve Test Bench adopts Top thrust + bottom claw dual clamping linkage technology. The unique dual clamping linkage structure can be switched freely according to the valve connection form. For flanged valves, the bottom claw clamps and the top presses for sealing; for welded and threaded valves, the top sealing disc is directly pressed for testing, with strong adaptability and no need for additional tooling.

High-precision graded pressure control system: Equipped with 8 groups of high-precision pressure gauges and independent pressure regulating valves for water and gas circuits, the pressure control accuracy reaches ±1.5 grade, and the pressure holding stability is better than the industry average, ensuring the authenticity and traceability of test data.

Heavy-duty durable hydraulic power unit: The piston rod is made of 45# steel with quenched and tempered treatment and chrome-plated surface, the hydraulic cylinder is made of seamless steel pipe, and the hydraulic pipeline is pickled and decontaminated as a whole, with low failure rate and long service life under high-strength continuous working conditions.

Modular scalable electrical control system: The centralized button control panel is designed with clear partitions, and electrical components adopt first-line brands with stable performance. It can be upgraded to a touch-screen intelligent data recording system according to customer needs to realize automatic storage of test data.
