PU225 pilot operated brass solenoid valve with max 16 bar pressure resistant

The SENYA PU225 Series is a high-performance 2/2-way solenoid valve designed for demanding industrial applications, featuring a rugged 58-3 brass alloy body that ensures durability and corrosion resistance. With an extended operating pressure range of 0.5-16 bar, this versatile valve series accommodates both low-pressure and medium-pressure systems across various industries. The valve’s enhanced design incorporates an optional 20W high-power coil configuration that delivers reliable operation in continuous duty applications while maintaining energy efficiency. A key innovation in the PU225 Series is the integration of a 316 stainless steel reinforcement skeleton within the diaphragm structure, significantly improving its mechanical strength and fatigue resistance to achieve an exceptional lifespan of 800,000 to 1,000,000 cycles – a substantial improvement over standard designs. The precision-engineered spring mechanism provides consistent elastic performance cycle after cycle, ensuring positive valve closure and enhanced operational reliability through thousands of repetitions.

This robust construction makes the PU225 Series particularly suitable for applications requiring frequent cycling or long service intervals, such as industrial automation systems, water treatment plants, and process control equipment. The valve’s internal flow path has been optimized to minimize pressure drop while maintaining the ability to handle moderate levels of particulate matter in the media. Available with various sealing material options, the PU225 can be configured for compatibility with different fluids including water, air, oils, and mild chemicals. The series’ design improvements focus on real-world performance requirements, combining enhanced durability features with maintenance-friendly accessibility for service components. Electrical connection options include standard DIN connectors with choices of protection ratings to suit different environmental conditions.

With its combination of extended pressure range capabilities, cycle life improvements, and reliable actuation performance, the SENYA PU225 Series represents a significant advancement in industrial solenoid valve technology, offering system designers a cost-effective solution that reduces maintenance frequency while ensuring consistent long-term operation. The valve meets international standards for quality and performance, and can be customized with special materials or configurations for specific application requirements in challenging industrial environments. These technical enhancements make the PU225 particularly valuable for applications where valve reliability directly impacts production continuity or system uptime.
