In applications such as testing systems and high-pressure air lines, standard regulators often face limitations:

• Insufficient pressure output
• Limited adjustment range
• Reduced stability under high pressure

High-pressure systems demand:

• Higher adjustable pressure limits
• Greater safety margins
• Wider operating conditions

• Adjustable pressure range: 0.05 – 3.5 MPa
• Proof pressure: 4.0 MPa
• Temperature range: -25 – 80°C

Engineering implication:
These parameters support stable operation in high-pressure environments while maintaining safety margins.

• High-pressure pneumatic testing systems
• Compressor outlet pressure regulation
• Industrial high-pressure air distribution

• Use QTYH when system pressure exceeds 0.8 MPa
• Suitable for low-temperature and fluctuating environments
• Select appropriate port size (1/4”–1”) for flow requirements

For high-pressure pneumatic systems, selecting the right regulator is essential for system stability. QTYH provides a practical solution with its extended pressure range and durability.
