Sun Hydraulics Scca-lbn-eb5 Sequence Sandwich Valve

What is a Sequence Sandwich Valve?

A sequence valve is used to manage the sequence under which hydraulic operations take place, such that one actuator is moved before another. In this way, it prevents system overload, minimizes power wastage, and provides for safe operation.

The SCCA-LBN-EB5 is a sandwich-style sequence valve, that is, it’s mounted between two other components in a hydraulic manifold stack. Its compact footprint streamlines system design and minimizes complex plumbing requirements.

Specifications of SCCA-LBN-EB5:

Manufacturer: Sun Hydraulics

Model: SCCA-LBN-EB5

Type: Sequence Valve

Mounting Style: Sandwich (ISO standard cavity)

Function: Regulates downstream pressure prior to flow allowance

Body Material: High-strength steel or aluminum

Seal Material: Buna-N (default), with optional Viton or others

Typical Flow Capacity: 30 GPM

Max Pressure Rating: Usually 5000 psi (config dependent)

Operating Temperature Range: -30°C to +120°C

How It Works

This valve passes flow to a secondary circuit only after a pre-set pressure is achieved in the primary circuit. Upon reaching the pressure setting, the valve opens and permits flow to the subsequent actuator. This is absolutely necessary in applications where synchronized operation is required — e.g., when a clamp needs to engage prior to a press cylinder being actuated.

Why Select Sun Hydraulics SCCA-LBN-EB5?

1. Compact Design
The sandwich-type design allows you to simply incorporate it into your manifold block without the need for extra piping. This conserves space and makes installation easier.

2. High Reliability
Sun Hydraulics is renowned for making tough and long-lasting parts. The SCCA-LBN-EB5 is built for high-pressure applications and functions well even in harsh environments.

3. Easy Maintenance
With its modular design, changing or maintaining this valve is efficient. No lengthy system shutdown or de-assembly required.

4. Individual Pressure Settings
The pressure setting may be easily tailored to the requirements of your system, providing versatility in multiple applications.

Uses of the SCCA-LBN-EB5 Valve

The valve is applied in industries where hydraulic systems play a critical role:

• Industrial Automation
In assembly and machine tools, it helps one cylinder complete its action prior to the next beginning.

• Mobile Equipment
Applied in construction equipment and agriculture vehicles to regulate attachments that require staged movement.

• Press Systems
Guarantees clamping before pressing to ensure safety and efficiency.

• Injection Molding Machines
Regulates the sequence of mold closure, injection, and ejection processes.
