Loop test for valve pressure and heat shock

High pressure & thermal shock testing for industrial valves

The test loop designed by LF Technologies enables valves subjected to high thermal and hydraulic stresses to be tested, qualified and proven. Thanks to a dual loop (hot and cold) combined with a dynamic pressurisation system, the test bench reproduces extreme operating conditions: static pressure up to 270 bar, temperature up to 280°C, flow rate up to 300 l/min.
This test bench is particularly suitable for critical applications: nuclear, energy, shipbuilding, oil & gas.

Main functions

• Cycled pressure testing up to 270 bar
• Heats up to 280°C / Cools down to 20°C
• Rapid hot/cold alternation for realistic thermal shocks
• Automatic cycling with position and torque control up to 1000 Nm
• Complete recording of test data

Bench structure

• Mechanically welded frame with secure testing area
• Lockable double glass doors (temperature/pressure conditions)
• Patented self-sealing ball joints for adaptation to all types of valves
• Lifting table on castors for easy assembly

Advanced testing system

• 2 hydraulic loops: 1 hot, 1 cold, + common test loop
• 3 servo-motorised syringes for pressure, shock and expansion compensation
• Customised circulators 300 l/min with flow control via variable speed drive

LabVIEW control software

• Manual or automatic control
• Intuitive programming of test sequences
• Real-time display of measurements: pressure, temperature, flow rate, torque
• Automatic reporting and data analysis module (optional)
