Product catalog summary

Overview:
The document provides comprehensive details on Hydrocontrol's hydraulic remote controls and foot pedals, designed for precise control of variable displacement pumps and directional control valves. These devices are noted for their high sensitivity, multiple adjustment curves, and low operating force, making them suitable for various applications.

Specifications:

Hydraulic Remote Controls: Maximum input pressure of 100 bar, oil input capacity of 12 l/min, and weight ranging from 1.5 to 4.8 kg. Standard threads include G 1/4 and 9/16”18 UNF.
Foot Pedals: Similar specifications to remote controls, with variations in weight and port configurations.
Supply Units: Designed for systems requiring lower pressure than the primary circuit, with a maximum input pressure of 350 bar and oil input capacity of 12 l/min.

Operating Principles:
The devices operate using direct-acting pressure reducing valves. Supply units reduce high-pressure fluid from the main circuit to a lower pressure suitable for hydraulic controls, using an accumulator for emergency power.

Key Features:

Robust construction with cast iron bodies and stainless steel plungers.
Ergonomic design for ease of use and low maintenance.
Compatibility with various hydraulic systems, including mobile machinery and industrial equipment.

Applications:
Suitable for mini-excavators, mini steer loaders, backhoe loaders, wheel loaders, tractors, and boom mowers.

General Specifications:

Fluid temperature range: -20°C to +80°C.
Fluid viscosity range: 10 to 300 cSt.
Maximum contamination level: 9 (NAS 1638) - 20/18/15 (ISO 4406:1999).
Recommended filtration: b10 > 75 (ISO 16889:2008).

Model Specifics:

HC-RCX Model: Features interchangeable controls with different lever rod types and options for mechanical detents.
HC-RCY Model: Offers reduced operating force and improved comfort, suitable for various machinery.
HC-RCL Model: Designed for wheel loaders with two-axis control and electromagnetic detent.
HC-RCL3 Model: Combines two-axis and single-axis controls, suitable for wheel loaders.
HC-RCM Model: Stackable single-axis lever remote control, ideal for piloting various hydraulic components.

Technical Specifications and Components Overview:

Metering Curves: Linear metering curves with and without steps.
Return Spring: "MD" type spring with specific preload and end stroke load.
Body Arrangement: Various configurations with different port positions and thread types.
Pedal Classification: Interchangeable controls with various pedal configurations.
Control Kit Classification: Includes bellows and swing-preventing dampening device.

Technical Specifications:

Main relief valve pressure setting is higher than the pressure reducing valve by about 10 bar.
Accumulators have a maximum working pressure of 210 bar and a working temperature range of -20°C to +80°C.
Dump valve technical specifications include operating voltages of 12 Vdc and 24 Vdc, with a power consumption of 20.5 W at 20°C.

Product Configurations:

Handle Positions: Various handle positions available, including straight and bent levers.
Optional Components: Customizable handles with special push-buttons and switches.

General Conditions:

Order Management: Orders are binding only if confirmed in writing.
Payment and Delivery: Payment terms are agreed upon at the start of supply.
Warranty and Complaints: Defects must be reported within 18 months.
Retention of Title and Confidentiality: Goods remain Hydrocontrol's property until fully paid.

Legal and Jurisdiction:

Italian law governs the supplies, with exclusive jurisdiction in Bologna courts.
