SoCare-MSI® supplies all series of valves from Sun Hydraulics 

Sun Hydraulics is a highly respected and pioneering company in the fluid power industry, known for its innovative and simple approach to hydraulic control.

Here's a comprehensive breakdown of what Sun Hydraulics is, its history, products, and why it's so significant.

Overview & Core Philosophy

Sun Hydraulics is a manufacturer of screw-in hydraulic cartridge valves and manifolds. Their core philosophy, often called the "Sun Solution," is to simplify hydraulic system design by:

1. Eliminating Leak-Prone External Plumbing: Instead of connecting individual valves with pipes and hoses, Sun's valves are screwed directly into a compact, machined block called a manifold.

2. Simplifying Design: They offer a vast range of standardized, pre-engineered cartridge valves that perform specific functions (like pressure control, flow control, or directional control).

3. Increasing Reliability: With fewer external connections, the potential for leaks and failures is dramatically reduced. The valves themselves are robust and simple in design.

A Brief History & Key Milestones

· 1970: Founded in Sarasota, Florida, by Robert Koski and Tom Lazzara. Koski's vision was to make hydraulics more reliable and easier for engineers to work with.

· The Innovative Business Model: Sun was famous for having no sales force. Engineers could call Sun directly and get expert technical advice, which built immense loyalty and trust within the engineering community.

· 1997: Went public on the NASDAQ (SNHY).

· 2019: Acquired by **Helios Technologies (NYSE: HLIO), a global industrial technology leader. Sun now operates as a core brand within Helios.

What Are Cartridge Valves and Manifolds?

To understand Sun, you need to understand their primary products:

· Cartridge Valves (or Cartridge Logic Elements): These are cylindrical valves with a specific hydraulic function. They are not used alone but are instead screwed into a manifold. Think of them like the electronic chips on a circuit board.

· Types: Check valves, relief valves, pressure reducing valves, flow controls, counterbalance valves, and more.

· Manifolds (or Logic Blocks): This is a solid block of metal (usually steel, aluminum, or ductile iron) with a complex network of internal passages drilled into it. The cartridge valves screw into threaded cavities in the manifold, and the internal passages connect them to form a complete hydraulic circuit.

· Advantage: This creates a compact, leak-free, and custom-designed control unit for a machine.

Analogy: If a traditional hydraulic system with pipe-connected valves is like a breadboard circuit with wires everywhere, a Sun manifold system is like a custom-printed circuit board (PCB)—integrated, clean, and reliable.

Key Product Lines

Sun's product portfolio is extensive, but it's built around these core families:

1. Solenoid Operated Directional Valves: These are their most recognizable products, often with a distinctive black plastic cap. They are two- or three-way valves used to control the direction of fluid flow, activated by an electrical signal.

2. Pressure Control Valves: Includes relief valves, pressure reducing valves, and sequence valves to manage force in a system.

3. Flow Control Valves: Used to regulate the speed of actuators (cylinders or motors) by controlling the flow rate.

4. Check Valves & Load Controls: Allow flow in one direction only or hold a load in place safely.

5. Manifolds: They offer custom-designed manifolds and also a line of "CETOP" style manifolds that follow a European standard.

Why is Sun Hydraulics So Highly Regarded?

1. Reliability and Simplicity: Their products are known for being incredibly durable and having a long service life. The simple screw-in cartridge design is inherently robust.

2. Technical Expertise & Support: Even after the acquisition by Helios, Sun maintains a reputation for deep technical knowledge and excellent customer application support.

3. Innovation: They continuously develop new products, such as proportional controls and integrated electronics, while maintaining their core philosophy.

4. Industry Standard: Sun's products have become a defacto standard in many industries. Engineers often design systems around the availability and performance of Sun valves.

5. Compact and Clean Design: The manifold approach saves space, reduces weight, and creates a much cleaner and more professional-looking hydraulic system.

Common Applications

Sun Hydraulics components are found in a wide range of mobile and industrial equipment, including:

· Mobile Machinery: Construction equipment (excavators, cranes), agricultural machinery (tractors, combines), forestry equipment, and refuse trucks.

· Industrial Machinery: Plastic injection molding machines, metal stamping presses, machine tools, and material handling systems.

· Marine: Winches, steering systems, and stabilizers on boats and ships.

Sun Hydraulics revolutionized hydraulic system design by promoting the use of screw-in cartridge valves and manifolds. Their focus on simplicity, reliability, and direct engineering support made them a trusted leader in the field. Now as part of Helios Technologies, they continue to be a dominant force, providing the essential "building blocks" for hydraulic circuits in countless industries worldwide.

If you are an engineer designing a hydraulic system, "using Sun valves" is often one of the first considerations due to their proven performance and extensive support resources.
