Technical Datasheet: Parker Kuroda Compact Solenoid Valve

Product Overview

The VA01PSC24-1P is an ultra-compact, high-speed, direct-acting 4-port solenoid valve developed under the Parker Kuroda brand. This valve features a unique pressure-balanced double-poppet construction with no internal sliding parts, making it exceptionally reliable, clean (oil-free operation), and capable of handling broad pressure variations spanning from deep vacuum up to standard positive pneumatic lines.

Pneumatic Configuration & Symbol Breakdowns

Port Configuration

• Type: 4-Port, 2-Position Configuration
• Port Allocations:
  • 1: Primary Pressure Supply Input Channel

  • 3 / 5: System Exhaust/Vent Discharge Channels

Symbol Diagram Analysis

The diagram on the faceplate outlines a standard single-solenoid spring return behavior layout:

• Left side (De-energized State): Internal return spring mechanism moves the internal spool poppet blocks back into position.
• Right side (Active Pilot Input): Electrical actuation shifts the internal flow path to swap output priorities between delivery channels 2 and 4.
