Description
The Consolidated 3900 series modular pilot-operated safety relief valve (MPV) features a separate, non-flowing pilot sub-assembly design making it well-suitable for use with both compressible and incompressible fluids. Optional pilot valve constructions offer either pop action or modulating action functionality to meet various pressure range, seat tightness, and blowdown requirements. Highly versatile, this valve technology offers ease of maintenance, high reliability, flexibility, and efficient operation and performance.
