SOLH VG342 Series 3 Port Solenoid Valve – Pilot Operated Poppet Type

Brand: SOLH by Richge Technology 

Product Overview

     Launched under SOLH brand by Richge Technology, the VG342 Series is a pilot-operated poppet-style 3-port solenoid valve with CE and ASME certification. It delivers outstanding zero-leakage sealing and ultra-stable precision air path control. Drawing on Richge’s 37+ years of pneumatic R&D and manufacturing experience, this poppet valve is perfectly matched with SOLH VBA pneumatic boosters and VBAT air storage tanks to form a complete medium-flow precision pressure control system. It is widely adopted in automation production equipment, high-voltage switchgear and precision fluid control stations, becoming a preferred pneumatic switching component for global system integrators, engineering contractors and industrial end users.

Core Product Advantages

1. Precision Pilot Poppet Construction with Ultra-Tight Sealing

     Adopting SOLH proprietary precision poppet spool and mature pilot control technology, VG342 features minimal pressure loss and instant response speed. The poppet structure realizes far lower internal leakage than slide spool valves, fully satisfying strict precision control demands for automated lines, precision machinery and fluid delivery systems.

2. Low-Power Energy-Saving Electromagnetic Coil

     Equipped with high-efficiency customized coils with two power grades: standard 1.3W and energy-saving version 0.4~0.55W. It maintains stable pilot driving performance under round-the-clock continuous operation, effectively cutting factory power consumption and meeting international energy conservation standards.

3. Convertible NC/NO Logic & Wide Pressure Adaptability

     No pipeline rework is required to switch between Normally Closed and Normally Open modes to fit diverse control logic. The valve operates steadily within 0.1–1.2 MPa working pressure range, applicable to compressed air, light oil and neutral inert gas working media.

4. Heavy-Duty Corrosion & Pollution Resistant Build

     The core poppet spool is manufactured from high-strength AISI 304 stainless steel. Main seals adopt ozone-resistant FKM / HNBR materials with FKM pilot seals for superior wear, corrosion and dust resistance. Compact body supports unrestricted multi-direction mounting to simplify on-site assembly and maintenance.

5. Full Compatibility with SOLH Pneumatic System & Mainstream Cabinets

     Optimized for combination with SOLH VBA boosters and VBAT air tanks to build integrated high-pressure pneumatic boosting control units. It also fits Schneider BLOKSET electrical switchgear and other standard industrial equipment, lowering cross-brand matching costs and boosting overall system stability for petrochemical, pharmaceutical and electronic production lines.

6. Global Certifications & Rigorous Quality Inspection

     All SOLH VG342 valves are produced under Richge’s ISO 9001 quality management system and pass CE, ASME and GB certification. Each finished product undergoes full pressure endurance and cycle life testing to meet export standards for Europe, America, Asia-Pacific and other overseas markets, supporting smooth project acceptance worldwide.

7. 50-Million-Cycle Long Service Life & Low Maintenance

     Wear-resistant poppet structure delivers a verified service life exceeding 50 million switching cycles. Built-in inlet filter blocks particulate impurities to reduce spool abrasion, cutting maintenance frequency and equipment downtime for textile printing, food processing and continuous automation equipment.
