Product Overview
The PARKER RH 2 FA is a direct-acting hydraulic check valve engineered to permit free flow in one direction while providing zero-leak, leak-tight sealing in the reverse direction. As a member of Parker’s RH series of modular line-mount check valves, the RH 2 FA is designed for in-line installation within hydraulic power circuits, where it prevents reverse flow, protects downstream components from pressure surges, and maintains circuit integrity during pump idle or shutdown periods. The valve operates purely on differential pressure across the poppet, requiring no external pilot signal or electrical actuation, making it a reliable passive safety element in high-pressure industrial hydraulic systems.

Engineering Features & Advantages
- Precision Performance: The spring-loaded poppet design delivers fast, positive closure with minimal cracking pressure, ensuring reliable reverse-flow prevention and accurate circuit isolation in demanding hydraulic loops.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and a robust housing that withstands pressure spikes and cyclic loading.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
- Low Pressure Drop: Optimized flow path geometry minimizes turbulence and energy loss during forward flow, supporting overall system efficiency.
Typical Industrial Applications
The PARKER RH 2 FA check valve is widely deployed in plastic injection molding machines, metallurgical presses, construction and marine hydraulic systems, and CNC machine tools. It is commonly used to protect pumps from reverse flow, isolate accumulator circuits, maintain pilot pressure in load-sensing systems, and prevent load dropping in holding circuits.
