Plastic Pressure Relief Valve (PRV) for Cement & Fly Ash Silos

Introduction

Searching for a durable plastic pressure relief valve (PRV) for silos? Shrinathji Infracon supplies weather-resistant, food-grade polymer PRVs engineered to safeguard silos from over-pressure and vacuum during pneumatic filling and discharge. Our valves protect silo integrity, filter housings, and conveying lines while maintaining clean, reliable operation.

Description

The PRV is a critical safety accessory that opens instantly when silo pressure exceeds the set limit and reseals automatically after normalization. Our plastic PRVs feature UV-stabilized housings, corrosion-proof internals, and elastomer seats for repeatable sealing. They mount on the silo roof/top head near the dust collector and interface seamlessly with existing vents and fill lines—ideal for cement, fly ash, GGBS, lime, and similar bulk powders.

Applications and Benefits
