Overview

This document provides detailed technical specifications and dimensional data for various pneumatic valve models produced by FARBO SRL. It covers different valve types including 3/2, 5/2, and 5/3 configurations, with distinctions between monostable and bistable pneumatic valves, as well as center configurations (closed, open, pressured).

Valve Types and Configurations

• 3/2 Pneumatic Valves: Available in monostable (normally closed or normally open) and bistable versions.
• 5/2 Pneumatic Valves: Offered in monostable and bistable configurations.
• 5/3 Pneumatic Valves: Featuring three center types: closed center (CC), open center (OC), and pressured center (PC).

Technical Specifications

The document includes comprehensive tables listing valve codes, flow rates (in liters per minute), and detailed dimensional measurements (in millimeters). Key parameters include:

• Flow Capacity: Ranges from 400 to 2250 lt/min depending on valve size and type.
• Port Sizes: Various G-thread sizes such as G 1/8", G 1/4", G 3/8", and G 1/2" are specified for different ports.
• Dimensions: Multiple dimensions labeled A, B, C, E, F, G1, H, I, L, M, N, O, P, Q, R, U, V, and others are provided to define valve size and mounting details.
• Weight: Valve weights range from approximately 70 grams to 770 grams depending on model and size.

Valve Codes and Model Identification

Each valve model is identified by a specific code (e.g., VPS8O, VPM8O, VPL4O, VPX2M) which corresponds to particular flow rates, port sizes, and configurations. The codes help in selecting the appropriate valve for application requirements.

Valve Functionality and Operation

The document distinguishes valve operation modes:

• Monostable Valves: Valves that return to a default position (normally open or normally closed) when not actuated.
• Bistable Valves: Valves that maintain their last position until actuated again.
• Center Positions for 5/3 Valves: Closed center stops flow, open center allows flow through, and pressured center maintains pressure in certain ports.

Recommendations and Usage Notes

While explicit procedural instructions are not detailed, the data tables and valve descriptions imply best practices for valve selection based on flow requirements, port compatibility, and operational mode. The precise dimensional data supports correct installation and integration into pneumatic systems.
