PU220 series is a 2/2-way direct-acting solenoid valve designed for demanding industrial fluid control applications. It offers wide media compatibility and high reliability, and is suitable for air, water, oil, and gas. The valve body features a large flow channel and an anti-interference structure, effectively reducing pressure loss, preventing clogging, and handling media containing impurities or unfiltered particles. It supports optional 20W high-power coils, enabling continuous 24/7 operation with overheat protection. The valve maintains stable flow and long service life even under limited filtration or confined installation conditions.
Features
- Compact design and easy to install, ideal for limited space
- Corrosion-resistant body with durable sealing (e.g., NBR, EPDM, Viton) for low maintenance
- Zero-pressure start with quick reaction time and higher flow capacity than pilot-operated types
- Optional protection levels and DIN connections, which is compliant with international standards
Applications
- Car wash
- Laundry equipment
- Air compressors
- Industrial water control systems
- Water pumps
- Water treatment systems
