HC-BV50

Product catalog summary

Introduction
The HC-BV50 monoblock valve is designed for applications requiring two pumps with different flow rates, available in 3+1, 4+1, and 5+1 versions. Its symmetrical body simplifies installation and offers functional advantages.

General Specifications
The document includes conversion factors for units of measurement and fluid compatibility, specifying temperature ranges and gasket types (NBR and VITON).

Technical Specifications
Standard conditions include a nominal flow rate of P1=50 - P2=150 l/min, nominal pressure of 350 bar, and operating temperature range of -25°C to +80°C. It supports kinematic viscosity from 10 to 460 mm²/s and requires a contamination level of 19/16 ISO 4406.

Order Modality
Guidelines for ordering the HC-BV50 valve are provided, including type, inlet, work section, and outlet arrangements, with coded sections for easy reference.

Dimensions
Dimensions and weights for the valve versions (3+1, 4+1, 5+1) are provided, along with standard thread specifications for ports.

Hydraulic Specifications
The valve features parallel circuits with diagrams illustrating components like pressure relief valves, antishock valves, and spools.

Typical Curves
Pressure drop and direct relief valve curves for different flow rates illustrate valve performance under various conditions.

Inlet Arrangement (P1)
Details on inlet arrangement with direct acting pressure relief valves, including hydraulic diagrams and layout configurations.

Specifications
Specifications for monoblock valves include direct acting pressure relief valves and spool types, with special machining for certain spools and classification based on hydraulic circuit descriptions.

Procedures
Instructions for ordering and identifying spools, including examples of classification and actuation, with Allen wrench assembly and clamping torque requirements.

Standards and Recommendations
Recommendations include maintaining an 8 bar backpressure, using specific PWM frequencies for proportional control, filtering degrees, and recommended pilot pipe sizes.

Control Systems
Descriptions of control systems, including electrohydraulic ON-OFF and proportional controls, with specifications for voltage, resistance, and current. Details on control tie rod assemblies and separate ordering of kits.

Auxiliary Valves
Section on auxiliary valves with limited details provided.

Overview
Technical specifications, ordering codes, and operational guidelines for hydraulic valves, including antishock and anticavitation valves, within a monoblock valve system.

Specifications

Setting Ranges: Pressure setting ranges for ports (A, B, C, D) from 25 to 350 bar.
Valve Types: Includes antishock, anticavitation, and plugged valves with specific ordering codes.

Hydraulic Schematics

Diagrams illustrate monoblock valve layout with right and left inlet options, including direct acting pressure relief valves.

Ordering Codes

Specific codes for valve configurations and settings, emphasizing setting values for auxiliary valves.

Spool Types and Actuation

Various spool types identified, including double-acting and single-acting configurations, with specific codes.
Spool actuation methods include protected lever, hydraulic actuation, and electrohydraulic control, with torque specifications for installation.

Spool Return Actuation

Three types of spring-loaded spool return kits described, with standard, soft, and heavy spring options.

Installation and Maintenance

Clamping torque values for components, including load check valve plugs and pressure relief valve bodies.
Special arrangements and float section identifications requiring specific valve body configurations.

Key Notes

Special machining required for certain spool types, with technical support recommended for custom circuit combinations.
Electrohydraulic controls stackable with proportional controls, with specific PWM frequencies suggested for optimal performance.
