HC-D4

Product catalog summary

Introduction
The HC-D4 sectional valve by Hydrocontrol S.p.A. is a modular valve designed for flexibility and adaptability across various applications. It supports a maximum flow of 80 liters/min at 350 bar and can be configured for parallel, tandem, and series circuits.

General Specifications
The valve operates under standard conditions with a nominal flow rate of 80 l/min and a pressure of 350 bar. It functions within a temperature range of -25°C to +80°C and supports kinematic viscosities from 10 to 460 mm²/s. The required contamination level is 19/16 ISO 4406 with a filtration level of β 10 > 75.

Fluid Compatibility
The HC-D4 is compatible with various fluids, including mineral oil and emulsions, with specific temperature ranges and gasket compatibility (NBR and VITON) for each type.

Order Modality
Ordering involves specifying the valve type, inlet, work section, and outlet arrangements. The valve assembly includes four tie rod kits, with lengths varying by section number.

Dimensions and Weights
Detailed dimensions and weights are provided for different valve configurations, varying with the number of sections.

Hydraulic Specifications
The valve supports parallel, parallel-tandem, and series circuits, each with specific operational characteristics. The carry-over connection (HPCO) option allows for extending the free flow channel to a second valve.

Hydraulic Schema
A detailed hydraulic schema for the HPCO version is included, showing the outlet section and conic plug position.

Typical Curves
Pressure drop curves for various configurations and settings are presented, including antishock and relief valve settings.

Inlet Section
Details on valve arrangements, including pressure relief and solenoid dump valves, are provided.

Spool Type and Actuation
Spools are classified by action and return types, with details on actuation mechanisms and ordering codes.

Specifications
Specifications for electrohydraulic and electropneumatic systems include clamping torque values and nominal voltages, with proportional control requiring a PWM frequency of 60-80 Hz.

Procedures
Installation requires a control tie rod kit, ensuring correct assembly to prevent misassembly.

Standards and Recommendations
Mechanical feedback is recommended for proportional control to enhance precision. Minimum working pressure is 5 bar.

Ordering Codes
Various codes are provided for different control configurations, including ON-OFF and proportional controls.

Auxiliary Valves
Descriptions of auxiliary valves, such as antishock and anticavitation valves, are included with setting ranges.

Intermediate Sections
Details on intermediate inlet and outlet sections, including pressure adjustments using relief valves, are provided.

Diagrams and Layouts
Hydraulic diagrams illustrate valve configurations and operations.

Overview
The document covers technical specifications and configurations for the HC-D4 valve, focusing on intermediate outlet and flow divider sections.

Specifications
The valve features an intermediate flow divider section with a flow adjustment range of 3 to 40 l/min.

Configurations
Complete configuration samples for the HC-D4 are provided, detailing components and operational principles.

Operating Principle
The flow divider section powers downstream sections with a user-defined flow rate, with excess flow directed to another valve or returned to the tank.

Installation and Maintenance
Assembly instructions include converting the valve from right-side to left-side inlet by rotating the spool and controls.

Product Identification
Each valve has an identification plate with a serial number and ordering code.

Additional Features
Available lever types and dimensions are listed, along with hydraulic diagrams for better understanding.
