GU-H With Check Valve Pressure Line Filter
Product Overview
GU-H With Check Valve Pressure Line Filter is an inline high-pressure FILTER, mounted on the pressure pipeline of the hydraulic system. This reliable FILTER removes solid particles, metal debris and other contaminants in pressurized hydraulic oil to protect precision hydraulic parts for various industrial and mobile Machine. Integrated with a built-in check valve, it prevents oil backflow when the system stops, avoiding element damage and oil contamination reverse flow, which greatly improves the safety and stability of the hydraulic system.

Working Principle
As an important FILTER on the pressure side of the hydraulic system, pressurized hydraulic oil flows through the filter housing and filter element. Impurities are trapped by the filter media to keep hydraulic oil clean. When the filter element is blocked and pressure difference reaches 0.35MPa, the indicator will send an alarm signal for element replacement. The built-in check valve closes instantly when the hydraulic system shuts down, blocking oil reverse flow. It avoids backflow impact on the filter element and prevents contaminated oil from flowing back to damage components of the Machine.
Core Advantages
1. Integrated check valve design, anti-backflow function, protects filter element and the whole hydraulic system during shutdown.
2. Heavy-duty housing withstands 32MPa high pressure, stable operation for heavy load Machine.
3. Multiple flow rates and filtration grades available, thread or flange connection for flexible installation.
4. Differential pressure clogging indicator to monitor working status of this FILTER in real time.
5. Large dirt holding capacity, low initial pressure drop; easy filter element replacement, low maintenance cost.
Application Range
This GU-H FILTER is widely equipped in the hydraulic system of metallurgical equipment, mining machines, plastic injection equipment, construction machinery and other heavy-duty Machine. It is suitable for high-pressure hydraulic circuits where oil backflow protection is required, protecting hydraulic pumps, valves and actuators from abrasive particle damage.
