Sub-Plate / Interface: Thickness 8-15 mm

Component Specifications

Definition

A precision-machined mounting plate that serves as an intermediate interface between solenoid valves and manifold blocks in fluid power systems. It provides standardized port connections, alignment features, and sealing surfaces to ensure leak-free operation and proper fluid flow distribution.

Working Principle

Provides mechanical mounting and fluid passage interface between solenoid valve cartridges and manifold blocks. Contains precisely machined ports that align with valve and manifold connections, with sealing grooves for gaskets or O-rings to prevent leakage. Distributes pilot air or hydraulic fluid to multiple valves from common supply ports.

Materials

Anodized aluminum alloy (typically 6061-T6) for corrosion resistance and lightweight; alternative materials include stainless steel (316L) for harsh environments or engineering plastics (POM, PEEK) for specific applications

Engineering Analysis

Risks & Mitigation

Port misalignment causing leaks
Incorrect gasket installation
Over-torquing mounting bolts
Material incompatibility with fluids

FMEA Triads

Trigger: Improper surface finish on sealing faces
Failure: Fluid leakage at interface
Mitigation: Specify Ra 0.8-1.6 μm surface finish and use appropriate gasket material

Trigger: Thermal expansion mismatch between materials
Failure: Seal compression loss during temperature cycles
Mitigation: Select materials with similar thermal expansion coefficients or use flexible sealing elements

Frequently Asked Questions

What is the difference between a sub-plate and a manifold?

A sub-plate is an interface component that connects individual solenoid valves to a manifold block, while a manifold is a multi-port block that distributes fluid to multiple valves. The sub-plate provides the mounting and sealing interface between them.

Can sub-plates be used with different valve brands?

Yes, if they follow the same mounting standard (e.g., ISO 5599). However, port configurations and sealing methods should be verified for compatibility between different manufacturers.
