Product catalog summary
Overview: This document provides detailed specifications for ROSS Europa's Series 21 Single Solenoid Pilot Inline Valves, focusing on both high and low temperature services. It includes model numbers, dimensions, and standard specifications for various valve types.
Valve Model Numbers:
  • Type H (High Temperature) Service: Includes model numbers for 2/2, 3/2, and 4/2 valves with various port sizes ranging from G 1/4 to G 1-1/2. The weight of the valves varies from 0.8 kg to 5.0 kg depending on the size.
  • Type O (Low Temperature) Service: Similar to Type H, this section lists model numbers for low temperature applications with the same range of port sizes and weights.
Dimensions: The document provides dimensions in millimeters for different port sizes, detailing measurements such as A, B, C, D, E, F, G, and H for each size category.
Standard Specifications:
  • Solenoids: Operate on AC or DC power with specific power consumption rates.
  • Manual Override: Non-locking metal button.
  • Temperature Ranges: Type H operates from -17° to 150°C, while Type O operates from -40° to 80°C. Special considerations are noted for temperatures below 4°C to prevent ice formation.
  • Flow Media: Recommended to use filtered air with a 5-micron filter.
  • Pressure Requirements: Inlet pressure should be between 2 to 10 bar, and pilot pressure must be equal to or greater than the inlet pressure.
  • Threads: BSPP standard, with NPT threads available upon consultation.
