5404 series high pressure pilot operated solenoid valve with piston PTFE seal design

The SENYA 5404 Series represents an advanced high-pressure pilot-operated solenoid valve solution engineered for the most demanding industrial fluid control applications. With an exceptional working pressure range spanning 0.5 to 50 bar, this robust valve series delivers reliable performance across diverse high-pressure environments, from moderate pressure systems to extreme applications. The valve’s pilot-operated mechanism ensures consistent and energy-efficient operation throughout its entire pressure spectrum, while maintaining rapid response times even under fluctuating pressure conditions.

Featuring an innovative piston design, the 5404 Series offers superior operational stability while significantly simplifying maintenance procedures. The modular construction allows for direct component replacement when servicing is required, minimizing system downtime and reducing long-term operating costs. The valve incorporates high-grade PTFE (Teflon) sealing elements that provide outstanding chemical resistance, making it suitable for handling aggressive media including acids, alkalis, solvents, and various corrosive industrial fluids.

Constructed with premium stainless steel (SS304/SS316) bodies, these valves demonstrate exceptional durability in harsh operating environments. The 5404 Series finds particular application in hydraulic power systems, oil and gas processing equipment, chemical injection systems, high-pressure cleaning installations, and industrial automation where reliable fluid control under extreme pressures is paramount.

Additional technical features include industry-standard connection options (NPT, BSPP, or SAE flanges), temperature resistance from -20°C to +150°C (with optional high-temperature configurations available), and compliance with international pressure equipment directives. The valve’s optimized flow path design minimizes pressure drop while maintaining high flow capacity, and its reinforced construction ensures long service life even in continuous duty cycles.

With its combination of robust construction, maintenance-friendly design, and superior material specifications, the SENYA 5404 Series establishes a new benchmark for reliability in high-pressure fluid control applications, offering plant operators a cost-effective solution that reduces total cost of ownership through extended service intervals and reduced maintenance requirements.
