Operating Features
Two-stage switching: Fast advance at low pressure, accurate pressure buildup at high pressure for improved efficiency.
For single-acting cylinders: Works with spring return or self-return cylinders; manual retraction with intuitive operation.
Ultra-high pressure capability: 300 MPa class pressure resistance, suitable for ultra-high pressure lifting, press fitting, straightening and similar applications.
Usage Recommendations
Recommended oil: ISO VG 10 machine oil or equivalent.
Recommended installation: Vertical mounting only; avoid horizontal or inverted use.
Typical Applications
Ultra-high pressure lifting and straightening of large molds and tooling
Precision leveling of bridges, construction and marine structures
Press fitting / disassembly of heavy components in metallurgy and steel equipment
Ultra-high pressure hydraulic testing for aerospace, rail transit and other equipment
Selection & Matching Notes
Best matched with single-acting cylinders / jacks of spring return or self-return type.
High-pressure hoses and fittings must be rated for 300 MPa; seamless steel tubes or high-strength hydraulic hoses are recommended.
Drain oil and apply rust protection before long-term storage; replace with new oil before reuse to ensure cleanliness.
