structural composition
- Head valve seat: Cast from aluminum alloy, featuring built-in oil inlet and outlet channels, a standard internal threaded interface, and pre-drilled mounting holes for a differential pressure transmitter;
- Filter cartridge housing: A carbon steel stretch cylinder with black anti-corrosion spray coating, providing pressure resistance and rust prevention; equipped with a built-in oil drain plug at the bottom for draining residual oil before filter replacement.
- Built-in filter element: Equipped with a dedicated PLA-specific filter element, available in options including glass fiber filter paper or metal woven mesh filter material; precision levels include 1μm, 3μm, 5μm, 10μm, 20μm, 30μm, and 80μm.
- Sealing assembly: oil-resistant rubber sealing ring, which effectively prevents bypass leakage of the medium.
core advantage
- Compact and space-efficient design, ideal for tight equipment layouts
- Easy installation and maintenance: simply unscrew the lower cylindrical section to remove the filter element; the oil drain plug at the bottom facilitates oil drainage.
- Carbon steel cylinder body with anti-corrosion coating, cost-effective and rust-resistant for long-term durability
- Optional differential pressure transmitter with real-time alarm for filter blockage to prevent filter failure
- Supports multiple filtration precision levels, catering to both fine filtration and coarse filtration applications.
- High versatility, featuring a domestically developed standardized structure with low replacement costs.

Competitiveness: Price is negotiable on large volumes.
Q: Spool Application Position?
A: The spool of the hydraulic support control valve is installed in the hole at the center of the control valve sleeve.
Q: Consequences of Malfunctions in the Control Valve Spool?
A: 1.External leakage of the valve body.
2.Loud fluid flow noise when the handle is in the working position, and slow movement of the upright column or jack.
3.Slow movement of the hydraulic support upright column and jack, accompanied by pressure blocking.
