HC-SVM

Product catalog summary
Introduction
The document introduces the HC-SVM/SVE selector valves, highlighting their high-performance design using quality materials and reliable gaskets. These valves are available in 3-6 way configurations, with performance dependent on application conditions. A critical parameter is the maximum operating pressure, and drainage is advised when pressure exceeds 160 bar to prevent mechanical stress.
General Specifications
The selector valves have specific leakage rates under test conditions, with fluid viscosity at 30 Cst and temperature at 50°C. Conversion factors for various units are provided, along with working conditions such as operating temperature from -25° to +80°C and kinematic viscosity from 10 to 460 mm²/s. Fluid compatibility is detailed for different fluids and gaskets.
Clamping Torque
Specifications for clamping torque are provided for various components of the selector valves, including bearing screws, cap screws, and solenoids, with specific torque values in Nm.
Dimensions and Typical Curves
Detailed dimensions and pressure drop curves for different models of selector valves are included, indicating nominal flow rates and maximum pressure capacities. Ordering codes for each model are also provided.
Spools and Actions
Spool identification and action classifications are detailed, with descriptions of circuit configurations and corresponding model codes. Layout and dimensional drawings for spool actions are outlined.
Ordering Modality
The ordering process for HC-SVM valves is explained, detailing product type, spool type, spool actuation, body arrangement, spool return action, and body thread.
Conclusion
The document emphasizes consulting the technical sales department for special applications or different technical specifications not covered in the catalogue. Hydrocontrol S.p.A. reserves the right to make modifications without prior notice and is not responsible for damages caused by incorrect product use.
Overview
The document provides technical specifications and configurations for various types of control levers and selector valves used in hydraulic and pneumatic systems, including detailed dimensions, ordering codes, and operational parameters.
Protected Lever
Dimensions and codes for protected levers are listed, including configurations where the lever is rotated 180 degrees. Key dimensions include A and B measurements, with thread sizes specified as M8 or M10.
Control Without Lever
Specifications for controls without levers are provided, detailing dimensions A, B, C, and D for different models, along with layout configurations and dimensional drawings.
Hydraulic Control
Details on hydraulic controls are given, including dimensions and spool return actions. The document specifies the omission of spool return action codes and provides a classification of selector valves.
Pneumatic Control
Specifications for pneumatic controls, both standard and rotated 180 degrees, are included. The functioning pressure is noted as 2 - 3.5 bar, with detailed dimensions and ordering codes provided.
Service Ports and Thread Ordering
The document outlines dimensions and ordering codes for service ports in 3-way and 6-way circuits, specifying thread types and configurations.
Lever Specifications
Information on lever types, including those with and without knobs, is provided. Dimensions and available lengths are detailed, along with ordering codes.
Solenoid Actuation
Specifications for solenoid actuation, both with and without drainage, are included. Maximum operating pressures are specified for 12 VDC and 24 VDC solenoids.
Pressure Drop Curves
The document includes pressure drop curves for various nominal flow rates and maximum pressures, providing a visual representation of performance characteristics.
