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
Technical Parameters
  • Port Size G1/4, G3/8, G1/2, NPT 1/4, NPT 3/8
  • Thickness 8-15 mm
  • Surface Finish Ra 0.8-1.6 μm
  • Pressure Rating Up to 16 bar (air), 315 bar (hydraulic)

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
