PREETAM DI Pressure Relief Valves are engineered to provide reliable overpressure protection for critical pipeline systems and industrial equipment. These pilot-operated valves automatically activate when system pressure exceeds predetermined levels, opening proportionally to relieve excess pressure and closing smoothly once normal conditions are restored. Constructed from high-grade GGG50 ductile iron with reinforced EPDM diaphragms and corrosion-resistant internal components, they deliver maintenance-free performance across various demanding applications. The fusion-bonded epoxy coating provides superior resistance to soil and water corrosion, while the factory-set or field-adjustable pilot system ensures precise pressure regulation from 1 to 16 bar.

These pressure relief valves find extensive usage across multiple industries including municipal water distribution networks, industrial processing plants, fire protection systems, and commercial infrastructure. Water utilities rely on them for protecting district metered areas and pressure zones, while industrial facilities use them in cooling systems, chemical processing lines, and manufacturing operations. Fire protection systems benefit from their consistent pressure maintenance, and pumping stations utilize them for both pressure relief and bypass applications. The valves' temperature range from -10°C to +80°C and drinking water safety certifications make them suitable for diverse environmental conditions and fluid types.

The business value of PREETAM DI Pressure Relief Valves lies in their proven reliability and cost-effective operation. By preventing overpressure incidents, these valves protect valuable equipment from damage, reduce downtime, and minimize maintenance costs. Their durable construction ensures long service life exceeding five years under normal conditions, providing excellent return on investment. The valves' customization options allow for project-specific configurations, while their compliance with international standards guarantees performance consistency. Hydraulic testing at 1.5 times PN for the body and 1.1 times PN for the seat ensures operational safety and reliability.
