PU225 Series Brass 2/2-Way Solenoid Valve
- Pilot Operated, Normally Closed
- Port Size: 1/8"–2"
- Fluid Temperature: -5°C to 80°C (-5℃ to 120℃)
- Operating Pressure: 0.5–1.6MPa
- Media: air, water, oil, gas
PU225 series is a high-performance 2/2-way solenoid valve engineered for demanding industrial environments. Built with a sturdy brass body and operates within a wide pressure range of 0.5–16 bar. Inside the valve, an innovative diaphragm reinforced with 316 stainless steel and a precision-balanced spring system greatly enhances fatigue resistance, extending its cycle life up to one million operations. The valve offers excellent sealing performance and stable operations, making it ideal for medium- and low-pressure fluid control systems.
- Pilot-operated structure suitable for medium- and low-pressure conditions up to 16 bar, with an optional 20 W high-power coil for continuous, energy-efficient operation
- 316 stainless-steel reinforced diaphragm offering excellent fatigue resistance and a long service life (800,000–1,000,000 cycles)
- Durable 58-3 brass body effectively resists corrosion and deformation, while the dynamically balanced spring mechanism ensures continuous operation and tight sealing
- Optimized flow passageway reduces pressure loss, handles media with trace impurities, and supports high flow performance
- Multiple sealing options (e.g., NBR, EPDM, and Viton) and DIN-standard electrical connections to meet various media and protection requirements
- Conforms to international standards, with extended maintenance intervals that effectively lower overall system operating cost
This solenoid valve is mainly used in industrial automation control systems in environments that handle water, air, oil, and mildly corrosive media. It is particularly suitable for medium and low-pressure applications such as:
- Water treatment systems
- Process equipment
- Air compressors
- Water pumps
- Car wash
- Laundry equipment
