At Industrial Parts and Components, our Pressure Valve-Integrated Filters are engineered for high-performance hydraulic and lubrication systems where maintaining consistent flow and protecting against pressure spikes is critical. These units combine high-efficiency filtration with an internal bypass or relief valve mechanism, ensuring that your system remains operational even under extreme conditions like cold starts or heavy contaminant loading. By integrating the valve directly into the filter head or element, we provide a compact, fail-safe solution that prevents seal blowouts and pump damage.

Key Features

• Precision-Calibrated Bypass Valve:Features an internal spring-loaded valve set to a specific differential pressure (e.g., 1.5 bar or 3 bar). This allows fluid to bypass the media if it becomes clogged, preventing the element from collapsing and ensuring continuous lubrication.
• Cold Start Thermal Protection:Designed to handle high-viscosity oil during initial startup. The integrated valve manages the temporary pressure surge, protecting the filter media until the fluid reaches operating temperature
• Dual-Stage Sealing:Utilizes high-grade fluorocarbon or nitrile O-rings to ensure a leak-proof interface between the valve mechanism and the filter housing, even under high-vibration conditions
