HC-D9

Product catalog summary

Introduction
The HC-D9 sectional valve by Hydrocontrol S.p.A. is designed for mini-excavators weighing 1 to 2.5 tons. It supports a maximum flow of 35 liters/min at 350 bar pressure. The valve is modular, compact, and lightweight, offering configurations such as 2 or 3 pump circuits and multiple control options.

General Specifications
The valve operates at a nominal flow rate of 35 l/min and a pressure of 350 bar, with a maximum line pressure of 20 bar. It functions within a temperature range of -25°C to +80°C and supports kinematic viscosity from 10 to 460 mm²/s. The contamination level is 19/16 ISO 4406, with a filtration level of β 10 > 75.

Fluid Compatibility
The valve is compatible with various fluids, including mineral oil and different emulsions. Specific temperature ranges and gasket compatibility (NBR and VITON) are provided for each fluid type.

Assembly Specifications
The valve assembly uses a tie rod kit, with lengths varying based on the number of sections. Each valve requires four tie rod kits, including a tie rod, two nuts, and two washers.

Hydraulic Specifications
The valve can be configured in parallel, parallel-tandem, or series circuits, affecting oil flow management and prioritization among service ports.

Ordering and Dimensions
Detailed ordering instructions are provided, including product type, inlet and outlet arrangements, and work section configurations. Standard thread types and dimensional drawings assist in correct assembly and installation.

Specifications
Specifications for hydraulic blocks in ports A and B are outlined, with a maximum pressure of 350 bar. Clamping torque and load limits for various configurations, including rotated positions, are detailed.

Procedures
Instructions for ordering codes and operation of intermediate inlet and outlet sections are provided. The use of auxiliary valves, including antishock and anticavitation valves, is described, with necessary setting values indicated.

Standards and Recommendations
The document emphasizes selecting appropriate settings for pressure relief valves, providing setting ranges for different flow conditions. Specific configurations are needed when using certain outlet sections.

Hydraulic Schemas and Diagrams
Hydraulic diagrams illustrate the layout and configuration of sectional valves and intermediate sections, crucial for understanding hydraulic component flow and connection.

Installation and Maintenance
General clamping torque values are provided for components like load check valve plugs and pressure relief valve bodies. Specific torque values are given for auxiliary valves and other critical parts.

Key Data from Tables
Tables include setting ranges for pressure relief valves, clamping torque values, and available lengths for lever types, essential for proper installation and operation.

Product Identification
Each HC-D9 valve has an identification plate with a serial number and ordering code for easy identification.

Assembly Instructions
Directional control valve casings have symmetrical galleries, allowing conversion from right-side inlet to left-side inlet by rotating the spool and controls 180°, except for spool types 012 and 013. The recommended curve for standard directional control valves is A01.

Installation and Maintenance
Installation and maintenance details emphasize the valve configuration's flexibility based on the inlet side.

HYDRAULIC SPECIFICATIONS SPECIFICHE IDRAULICHE Parallel circuit Circuito Parallelo When the spool is operated it intercepts the switch gallery by diverting the flow of oil to service port A or B. If two or more spools are actuated at the same time, the oil will power the service port that has the lower load by selecting the path with the least resistance; by throtting the spools, the flow of oil can be divided between two or more service ports. HYDRAULIC SCHEMA Il cursore quando viene azionato, intercetta il canale di libera circolazione deviando il flusso d’olio agli utilizzi A o B. Se due o...

HYDRAULIC SPECIFICATIONS Carry-over connection (HPCO) SPECIFICHE IDRAULICHE Collegamento carry-over (HPCO) This option, available on all HC-D9, allows the monoblock to feed a second valve, by extending the free flow channel. In this configuration, the valve needs a separated port for the connection to tank. Questa opzione, di serie sul distributore HC-D9, permette il prolungamento del canale di libera circolazione all’esterno, alimentando così un secondo distributore. Il distributore così configurato necessita di uno scarico per le utenze. It is possible to transform sectional valve from standard...
