Product catalog summary

Introduction
The HC-M50 monoblock valve by Hydrocontrol S.p.A. is designed for mobile equipment applications, featuring a symmetric valve body for flexible spool control. It supports parallel and tandem circuits and includes integrated functions like electric load limit and solenoid dump valve, enhancing versatility.

General Specifications
The document provides conversion factors for metric and British systems, detailing units for length, mass, force, volume, and pressure. It specifies fluid compatibility, temperature ranges, and gasket types for different fluids, including mineral oil and water-based solutions.

Standard Working Conditions
The HC-M50 operates at a nominal flow rate of 50 l/min (14.5 GPM) and a pressure rate of 350 bar (5000 psi). 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 specified as 19/16 ISO 4406, with a filtration level of β 10 > 75.

Technical Specifications
The valve can have 1 to 7 working sections, with a spool stroke of 5.5 mm and a spool pitch of 35 mm. Details on ordering modalities, dimensions, and hydraulic specifications, including parallel and parallel-tandem circuit configurations, are provided.

Order Modality
Ordering involves specifying the monoblock type, inlet arrangement, work section arrangement, and outlet arrangement. Each section's configuration must be repeated for every work section in the monoblock.

Dimensions
The HC-M50 family is divided into four model categories based on circuit type and auxiliary valve presence. Standard thread sizes for ports are provided, with variable dimensions for different model types.

Hydraulic Specifications
The document describes the operation of parallel and parallel-tandem circuits, explaining how oil flow is directed to service ports A or B and how multiple spools can be actuated simultaneously.

Specifications and Dimensions
Specifications and dimensions for various hydraulic components are outlined, with a maximum pressure (P max) of 350 bar. Dimensions are provided in millimeters for different configurations.

Clamping Torque
The clamping torque for components is specified as 4 - 6 Nm, consistent across different configurations.

Flow Inhibition
Flow inhibition is described for ports A and B, with specific configurations inhibiting flow on either port A or B.

Ordering Codes
Various ordering codes are provided for different configurations of load limits and control types, including dual control and rotated configurations.

Electrical Specifications
Electrical specifications for load limit kits include voltage, current, and protection degree (IP 65), with recommendations for connecting inductive loads.

Electrohydraulic Control
Specifications for electrohydraulic control systems include maximum inlet pressure, reduced pressure, and back pressure. ON-OFF and proportional control systems are described, with specific ordering codes and configurations.

Auxiliary Valves
Information on auxiliary valves, such as antishock and anticavitation valves, is provided, including setting ranges and ordering codes.

Outlet Arrangement
Details on outlet arrangements for monoblock valves specify configurations for outlets on the top or sides.

Monoblock Valve Identification and Specifications
1. Outlet Arrangement
Classification of monoblock valves with two outlets is provided, detailing the arrangement of ports (P and T) on the valve body, identified by specific codes like MJK and MJL.

2. Tandem Circuit Identification
Three configurations for tandem circuits in monoblocks are described, requiring a special valve body for each configuration.

3. Lever Identification
Levers are classified by length and type, with ordering codes for levers with knobs and joystick control.

4. Installation and Maintenance
General clamping torque specifications are provided for various components, with specific torque values listed.

5. Product Identification
Each HC-M50 monoblock valve includes an identification plate with a serial number and ordering code.

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. Il cursore quando viene azionato, intercetta il canale di libera circolazione deviando il flusso d’olio agli utilizzi A o B. Se due o più cursori vengono...

HYDRAULIC SPECIFICATIONS Carry-over connection (HPCO) SPECIFICHE IDRAULICHE Collegamento carry-over (HPCO) This option, available on all HC-M50, 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 sui monoblocchi HC-M50, 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 monoblock from standard...
