SV30PA1-40B Hydraulic Valve Detailed Overview

I. Core Functionality

• Preventing reverse oil flowin hydraulic systems, ensuring oil flows in one direction under normal conditions.

• Allowing controlled bidirectional flowwhen pilot pressure is applied, enabling flexible system operation.

• Providing pressure holding capabilityby sealing oil lines when no pilot signal is present, acting as a hydraulic lock.

II. Technical Specifications

【表格】

III. Design Features

1. Conical Spool Design

• Ensures superior sealing performance under high pressure, minimizing internal leakage.

• Enhances bidirectional flow control responsiveness when pilot pressure is applied.

2. Modular Construction

• Plate-mounted design facilitates easy integration into hydraulic manifolds.

• Interchangeable components enable flexible system configuration.

3. Dual Control Modes

• Hydraulic Pilot Control: Actuates via external hydraulic pressure for automated system integration.

• Manual Override: Optional mechanical override for maintenance or emergency operations.

4. Robust Sealing

• High-quality elastomeric seals (e.g., nitrile rubber) provide long-term durability in harsh environments.

IV. Typical Applications

• Construction Machinery: Excavators, loaders, and cranes for controlling boom/arm movements.

• Agricultural Equipment: Tractors and harvesters for hydraulic cylinder control.

• Material Handling: Forklifts and telehandlers for lift/lower functions.

• Industrial Systems: Presses and molding machines for precise actuator positioning.
