Richge VP Series Large Size 3 Port Solenoid Valve

Brand: SOLH by Richge Technology

Product Overview

     Richge Technology’s SOLH brand VP Series is a pilot-operated large-bore 3-port solenoid valve certified with CE and ASME standards. Equipped with ultra-high flow channels and multi-spec energy-saving electromagnetic coils, this valve achieves a service life exceeding 50 million cycles. It delivers perfect compatibility with SOLH VBA pneumatic boosters and VBAT air storage tanks, widely deployed in heavy-duty industrial automation and high-voltage electrical cabinet control systems.

Core Product Advantages

1. Oversized Port & Super High Flow Performance

     Designed with proprietary optimized internal flow passages independently developed under the SOLH brand, the VP series covers port sizes ranging from Rc 3/8" to 1-1/2", with a maximum Cv flow coefficient up to 7.0 and peak exhaust flow reaching 28 dm³/(s·bar). Its low pressure drop characteristic enables fast valve response and steady air supply, fully meeting the high-flow actuation demands of large-bore cylinders, heavy clamping jigs and heavy-duty automation equipment.

2. Multi-Grade Energy-Saving Low Power Coil

     SOLH VP series adopts self-developed high-efficiency electromagnetic coils with three optional power grades for flexible matching: standard 1.55W, medium energy-saving 0.55W and ultra-low power 0.4W. The coil maintains powerful driving force under long-duration continuous operation and effectively cuts overall power consumption of factory pneumatic systems.

3. Convertible NC / NO 3-Port Logic, Wide Media Adaptation

     Users can switch between Normally Closed and Normally Open operation without modifying pipeline layout, adapting to diverse pneumatic control logic. The valve supports both positive pressure circuits within 0–1.0 MPa and vacuum environments down to -101.2 kPa, greatly expanding its applicable working scenarios.

4. Industrial Heavy-Duty Anti-Corrosion & Anti-Pollution Structure

     The main sealing ring adopts ozone-resistant HNBR material, while the pilot valve is fitted with FKM seals to realize reliable zero-leakage performance. A built-in miniature filter prevents dust and oil contamination from blocking the pilot spool, ensuring stable operation in dusty and humid industrial workshops. Direction-free mounting design simplifies on-site assembly procedures.

5. Perfect Matching with Full SOLH Pneumatic Product Line

     Optimized to form an integrated high-pressure boosting control unit when combined with SOLH VBA pressure boosters and VBAT air tanks under Richge Technology. It also supports matching with Schneider BLOKSET electrical cabinets and other mainstream industrial equipment, reducing cross-brand fitting and assembly costs for customers.

6. Global Standard Certifications & Strict Quality Control

     All SOLH VP valves are manufactured under Richge Technology’s ISO 9001 certified quality management system, and pass CE, ASME and national GB standard authentication. Every finished unit undergoes full pressure endurance and cycle life testing to satisfy international export standards and smooth acceptance for overseas industrial projects.

7. Ultra-Long Service Life & Low Maintenance Cost

With a verified service life of 50 million switching cycles, the valve extends component replacement intervals and cuts equipment downtime, bringing sustained long-term economic benefits to automated production lines.
