Diaphragm Type Solenoid Control Valve Overview

This document provides technical specifications, material details, and performance data for diaphragm type solenoid control valves available in various sizes ranging from 2" to 12".

Performance Specifications

• Flow Rate vs. Dynamic Pressure: Graphs illustrate the relationship between downstream dynamic pressure (in kg/cm²) and flow rate (liters per minute) for valve sizes 1.5" to 3" and 4" to 8".
• Pressure Ratings: Working and test pressures are specified for different materials:
  • Ductile Iron: Working pressure up to 25 bar, Test pressure up to 35 bar
  • Bronze: Working pressure up to 21 bar, Test pressure up to 16 bar
  • Stainless Steel: Working pressure up to 35 bar, Test pressure up to 22 bar

Valve Sizes and Dimensions

Material Composition

The valve components are made from various materials depending on the part and valve type:

• Cover: Ductile Iron, Bronze, Stainless Steel
• Center Shaft, Diaphragm Fixed Bar, Fixed Bolt, Sealing Spacer, Seat, Shaft, Diaphragm, Main Body, Spring, Strainer: Combinations of Stainless Steel, Bronze, Ductile Iron, and elastomers such as NBR and Viton.
• Stop Valve and Solenoid Valve: Bronze and Stainless Steel (optional components)

Additional Notes

• Thread end and flange end connections are available.
• Optional components include stop valve and solenoid valve.
• Elastomer seals vary between NBR and Viton depending on the valve model.

This summary captures the essential technical data, material specifications, and performance parameters necessary for selecting and applying diaphragm type solenoid control valves in industrial settings.
