Frequently Asked Questions

What makes the VH Series "Very Heavy Duty" compared to standard NFPA?
The VH Series utilizes oversized, high-tensile alloy rods, pre-stressed tie rods, and reinforced head/cap blocks specifically designed to withstand the extreme shock loads and fatigue of heavy industrial pressing.
What is the maximum pressure rating for this series?
Our VH series is rated for a nominal pressure of 3000 PSI (210 Bar), with customized versions capable of handling up to 5000 PSI (350 Bar) for critical heavy-duty cycles.
How do you manage heat dissipation in heavy-cycle applications?
For high-frequency heavy duties, we offer optional specialized seal materials (Viton/PTFE) and can integrate external porting for oil circulation cooling to prevent thermal seal degradation.
Are custom bore sizes and stroke lengths available?
Yes. We specialize in large-bore engineering, offering custom diameters up to 24 inches (600mm) and strokes reaching 10 meters, fully supported by our heavy-duty manufacturing facility.
What type of fatigue testing is performed on VH cylinders?
Beyond static pressure tests at 1.5x rating, we perform ultrasonic internal audits on all critical welds and high-load cycle simulations to ensure structural integrity under repetitive heavy stress.
What is the global service support for the VH Series?
We provide a 12-month heavy-duty warranty and offer global technical consulting. Replacement seal kits and critical spare parts are maintained in stock for rapid international dispatch.
