Sun Hydraulics Proportional Valve | RBAC-LAN RBAA-LAN RPGS-LAN | Solenoid Operated

Sun Hydraulics Proportional Solenoid-Operated Directional & Pressure Valves

Product Overview: Sun Hydraulics Proportional Valves are globally recognized for their superior linear control and patented “Floating Style” design. This unique construction allows internal components to self-center during installation, neutralizing internal stresses caused by manifold machining tolerances or excessive torque. This ensures high-precision spool movement even under complex proportional solenoid signals. This category features premier models for electronic control: RBAC-LAN, RBAA-LAN (Proportional Flow Control), and RPGS-LAN, RPIS-LAN, RQEB-LAN (Pilot-operated Proportional Pressure Control).

Engineered for high-precision and long-life requirements, these cartridges are the premier choice for mobile equipment remote control, industrial automation lines, injection molding pressure regulation, and electro-hydraulic servo systems.

Key Technical Advantages:

• Precision Proportional Control: When paired with Sun digital controllers, these valves provide seamless linear regulation of flow or pressure with rapid response and minimal hysteresis.

• Floating Cartridge Technology: The unique two-piece floating construction significantly reduces the risk of spool binding caused by mechanical stress, enhancing system repeatability.

• High-Durability Coils: Fully encapsulated coil designs offer excellent ingress protection (up to IP69K), making them suitable for harsh outdoor environments.

• LAN High-Performance Specs: Featuring L (Standard screw/Manual override), A (Range/Ratio code), and N (Buna-N seals) for optimal sealing integrity in standard applications.
