VNB114 Series 2-Way Stainless Steel Solenoid Valve | External Pilot Process Fluid Control Valve

Brand: SOLH by Richge Technology | Full Compatible Replacement for SMC VNB114 Original Series

1. Product Positioning

     The SOLH VNB114 is an external pilot 2-way stainless steel solenoid valve optimized for complex fluid working conditions. Focusing on corrosion resistance, high cleanliness and wide fluid compatibility, it is specially designed for water, weak acid & alkali solutions, food-grade fluids, and industrial cleaning liquid control. Inheriting the high-reliability on-off performance of the VNB series, the combination of full stainless steel body and multi-type sealing materials balances sanitary performance and long-term durability. It serves as the core fluid control valve for chemical, food & pharmaceutical, semiconductor cleaning and other scenarios requiring strict material and cleanliness standards, fully interchangeable with original SMC VNB114 series.

2. Core Product Features

     • Full Stainless Steel Body & Superior Corrosion Resistance: The main valve body adopts high-quality stainless steel material, effectively resisting chemical corrosion and rust oxidation. It stably adapts to corrosive fluids and humid industrial environments, greatly extending the service life of fluid pipeline equipment.

     • External Pilot Drive & Stable Action: Adopting external pilot structural design, driven by 0.25–0.7MPa pilot pressure. It features reliable opening/closing action and fast response speed, perfectly suitable for large-flow and high-pressure fluid control scenarios that require stable and continuous switching.

     • Multi-Sealing Options for Wide Fluid Coverage: Supports three mainstream sealing materials: NBR, FKM and EPR. It can adapt to diverse media including water, oil, compressed air, vacuum, weak acid & alkali solutions and food-grade fluids, realizing one valve for multiple working conditions and reducing model inventory costs.

     • High-Cleanliness & Sanitary-Friendly Design: The smooth stainless steel body surface leaves no residual dirt, convenient for daily cleaning and maintenance. It fully meets the dust-free and sanitary production requirements of food & beverage, pharmaceutical manufacturing and semiconductor precision cleaning circuits.

     • Compact Structure & Flexible Installation: Mini integrated compact structure saves pipeline installation space. Compatible with direct outlet and DIN socket wiring modes, matched with standard Rc (PT) thread interface. It features convenient piping & wiring and efficient later maintenance.

     • High Protection Grade & Long-Term Durability: Reaches IP65 dustproof and splash-proof protection grade, adapting to complex on-site environments. The coil adopts Class B insulation with low temperature rise, supporting long-term continuous energized operation and maintaining stable fluid switching performance.

4. Typical Application Scenarios

     • Chemical Industry: On-off control for corrosive fluid pipelines, weak acid & alkali solutions and industrial cleaning liquid circuits, resisting medium corrosion and ensuring long-term stable operation.

     • Food & Pharmaceutical Industry: Suitable for drinking water, medicinal liquid and food-grade fluid control. The easy-to-clean stainless steel body meets sanitary production standards and avoids medium residue contamination.

     • Semiconductor & Electronic Manufacturing: Applied to ultra-pure water and precision cleaning liquid circuits, featuring pollution-free and corrosion resistance to support high-precision clean production processes.

     • General Industrial Automation: Reliable switching control for cooling water, lubricating oil, compressed air and vacuum systems, adapting to various conventional fluid pipeline working conditions.

5. Model Code Explanation & Typical Examples

     The VNB114 model code intuitively defines sealing material, port size, voltage and wiring mode for precise selection.

     • VNB114CS-8A-5GB: Stainless steel body + EPR sanitary seal + 8A (1/4) port + DC24V + direct outlet wiring type

     • VNB114FS-8A-5DZ: Stainless steel body + FKM corrosion-resistant seal + 8A (1/4) port + DC24V + DIN socket type (with indicator light & overvoltage protection)

One Sentence Summary

     The SOLH VNB114 2-way stainless steel solenoid valve integrates full corrosion-resistant stainless steel body, stable external pilot drive, multi-sealing wide-medium adaptation and IP65 high protection performance, serving as a high-reliability on-off control valve for corrosive, sanitary and high-cleanliness fluid working conditions, fully compatible with SMC original VNB114 series.
