The PB25 Series Pressure Relief/Reducing Valve
The PB25 series represents an advanced pressure management solution for hydraulic systems, integrating precision engineering with robust construction. This dual-function valve combines pressure regulation and system protection capabilities, delivering reliable performance across diverse industrial applications.
Constructed with high-strength alloy steel and enhanced surface treatment, the valve demonstrates exceptional resistance to wear and corrosion. Its hydrodynamically optimized body features dual relief channels and a tapered spool design, achieving ±1.5% FS regulation accuracy within 0.5-25MPa operational range. The integrated damping chamber effectively minimizes pressure fluctuations during flow variations.
The ergonomic adjustment mechanism incorporates shock-resistant calibration dials, enabling precise field adjustments. Standard port configurations (G1/4, G3/8, G1/2) ensure compatibility with mainstream hydraulic systems. The built-in filtration module (≥50μm particle retention) makes it particularly suitable for construction machinery and industrial environments with potential fluid contamination.
Operating reliably across -20℃ to +120℃ temperature range through specialized sealing components, the valve is recommended for use with ISO VG32-VG68 grade hydraulic fluids. Proven applications span petrochemical processing, metallurgical systems, and marine power installations. Maintenance protocols suggest periodic inspection of spring tension and ensuring unobstructed relief channels.
This product embodies modular design philosophy, allowing flexible integration into existing pressure control systems while maintaining compact dimensions (156×82×68mm). Optional accessories include pressure gauges adaptors and remote pilot operation kits for customized configurations.
