Cartridge Body: Temperature Range -20°C to +120°C

Component Specifications

Definition

The Cartridge Body is a precision-machined component that serves as the primary structural element of a solenoid valve cartridge. It houses the valve seat, spool or poppet assembly, and provides internal flow channels for directing hydraulic or pneumatic fluid. Designed for insertion into machined cavities in manifolds or blocks, it features standardized mounting dimensions and sealing surfaces to ensure leak-free operation. The body typically includes threaded ports for fluid connections, pilot pressure channels, and mounting features for the solenoid coil assembly.

Working Principle

The Cartridge Body provides a sealed housing that directs fluid flow through internal passages when the valve spool or poppet is actuated by the solenoid. It maintains pressure integrity while allowing precise control of fluid direction, flow rate, and pressure through its machined channels and interfaces.

Materials

Typically manufactured from carbon steel (AISI 1045, 12L14), stainless steel (303, 304, 316), brass (C36000), or aluminum (6061-T6) with hardness requirements of 25-35 HRC for steel components. Surface treatments may include zinc plating, nickel plating, or black oxide coating for corrosion resistance.

Frequently Asked Questions

What is the difference between a cartridge body and a conventional valve body?

Cartridge bodies are designed for insertion into machined cavities in manifolds or blocks, eliminating external piping and reducing space requirements, while conventional valve bodies have external port connections and standalone mounting.

Can cartridge bodies from different manufacturers be interchanged?

Interchangeability depends on compliance with ISO 4401 or DIN 24342 standards. While dimensional standards exist, port configurations and internal features may vary between manufacturers.

What maintenance is required for cartridge bodies?

Regular inspection for external damage, checking seal surfaces for wear, and ensuring proper torque on mounting hardware. Internal cleaning may be needed if contamination occurs.
