Tokio Keiki TC2-G-03 Valve Subplate
The TC2-G-03 is a precision-manufactured mounting subplate produced by Tokio Keiki. Designed for hydraulic valves with an ISO 4401-03 (G03/Cetop 3) mounting interface, this subplate serves as the foundational connection between the control valve and the hydraulic system’s plumbing. Unlike larger manifold blocks, the TC2 series is optimized for single-valve installations, providing a stable, high-pressure sealing surface that ensures the integrity of the hydraulic circuit under demanding industrial conditions.
Technical Specifications and Performance
The TC2-G-03 is built to support high-pressure industrial hydraulic components. According to the manufacturer’s technical standards:
-
Valve Interface: ISO 4401-03-02-0-05 (Size 03).
-
Connection Type: Bottom Piping (G designation).
-
Port Thread Size: 1/4 BSPP or NPT (Note: The TC2 is typically the 1/4″ port version, whereas the TC3 features 3/8″ ports).
-
Maximum Operating Pressure: 21 MPa (210 bar).
-
Material: High-grade cast iron or steel with precision-ground mounting face.
-
Compatibility: Compatible with DG4V-3, TGMC, and other G03 series valves.
Key Features for Industrial Applications
Optimized for Compact Systems
The TC2-G-03 is the ideal solution for compact hydraulic power units where space is at a premium. Its 1/4″ porting size is specifically designed for lower to medium flow rates, reducing the overall footprint of the assembly while still providing the robust mounting required for 21 MPa operation.
Leak-Proof Bottom Porting
The «G» configuration indicates that all hydraulic connections are located on the bottom of the plate. This allows for a clean «top-down» installation where the valve is easily accessible for maintenance while the piping remains hidden and protected beneath the mounting surface or manifold deck.
