Product Overview
The SHIMADZU 228-48858-95 is a precision-engineered solenoid valve assembly designed for high-performance fluid control in analytical instrumentation and industrial process systems. Manufactured by Shimadzu, a global leader in precision instrumentation and fluid handling technology, this solenoid valve operates on an electromagnetic actuation principle: an electrical current energizes a coil, generating a magnetic field that displaces the internal plunger or poppet, thereby opening or closing the fluid pathway with rapid, repeatable response. As a critical component within HPLC (High-Performance Liquid Chromatography) systems and general process fluid circuits, this valve provides accurate on/off flow switching, solvent selection, and pressure isolation. Its compact architecture, chemically resistant wetted materials, and leak-tight sealing make it an essential control element for laboratories and industrial facilities requiring precise, low-volume fluid management under moderate operating pressures.

Engineering Features & Advantages
- Precision Performance: Fast-acting solenoid actuation delivers rapid, repeatable open/close cycles with minimal dead volume, ensuring accurate fluid metering and switching in HPLC and process circuits.
- Leak-Tight Sealing: Precision-machined plunger and seat geometry provides bubble-tight shutoff, preventing cross-contamination and solvent loss during critical analytical sequences.
- Chemical Compatibility: Wetted components are selected for resistance to common HPLC solvents and process fluids, extending service life in aggressive media environments.
- Industrial Reliability: Built for continuous operation under severe industrial and laboratory conditions, with stable coil performance and low heat generation.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Shimadzu OEM standards, enabling drop-in replacement without system modification.
Typical Industrial Applications
This solenoid valve is widely deployed in HPLC and analytical instrumentation for solvent selection, gradient switching, and flow path control. It is also used in pharmaceutical and chemical process systems for precise reagent dosing, in laboratory automation platforms requiring low-volume fluid routing, and in general industrial process and pneumatic circuits where compact, electrically actuated on/off fluid control is required. Additional applications include environmental monitoring analyzers, food and beverage quality testing equipment, and pilot-scale chemical reactors demanding reliable, repeatable valve actuation.
