Directional Control Valves

Product catalog summary
Overview: The document provides comprehensive technical specifications and operational guidelines for PowrFlow™ Directional Control Valves, which are designed for precision control in hydraulic systems. These valves are known for their durability and reliability, backed by a 3-year warranty, and are rated for 5000 PSI with Viton seals as standard.
Specifications: The valves support flow rates up to 20 GPM and are compatible with various hydraulic fluids, including petroleum and water-based fluids. They conform to NFPA, ANSI, and ISO standards and are available in multiple spool options. Specific models like VSD03M and VS5M are highlighted, with detailed specifications such as maximum pressure, temperature range, and flow rate.
Applications: These valves are suitable for a wide range of applications, including machine tool indexing, motion control devices, lift equipment, compactors, and food processing machinery.
Valve Types: The catalog includes solenoid actuated, lever actuated, air actuated, and cam actuated valves, each with specific features such as CSA and CE certifications, wet armature solenoids, and corrosion-resistant components.
Performance and Operation: The valves are designed to handle high flow rates and pressures, with configurations to prevent oil leakage and ensure easy maintenance. Performance metrics such as solenoid shift time, spring return time, and cycling frequency are provided for both AC and DC solenoids.
General Specifications: Recommended fluid temperature is up to 200°F, with operating viscosities ranging from 80 to 350 SUS. The valves require ISO 18/16/13 filtration and offer flexible mounting positions.
Electrical Options: Various electrical connection options are detailed, including top electrical connection boxes with different pin configurations and surge suppressors. Options for hazardous duty locations are also highlighted.
Flow and Pressure Data: Flow curve numbers and typical pressure drop curves illustrate the relationship between flow rate and pressure drop across different spool types and configurations.
Ordering Information: Detailed ordering codes are provided for selecting the appropriate valve configuration, including spool types, solenoid options, and mechanical features. The importance of selecting the correct configuration for specific operational needs is emphasized.
Additional Features: Anti-shock valves are designed to reduce hydraulic system shock by providing slower spool movement. Solenoid indicator lights and options like Viton and Buna-N seals are also available.
Installation and Maintenance: Valves are designed to be mounted on D05 or D08 subplates, with specific dimensions and mounting instructions provided. Electrical boxes can be rotated 180 degrees, and connectors must be ordered separately.
Notes: Performance is measured on a four-way circuit and may be reduced if a three-way circuit is used. All pressure drops are based on a fluid viscosity of 100 SUS and a specific gravity of 0.87.
