The
Type 3900 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.
Features
The modular design offers one common platform that
covers a wide range of applications.
Modular design helps reduce overall inventory and
maintenance costs.
Top-entry main valve design provides ease of access for
maintenance and parts replacement.
Optimizing pilot function with the specific pressure
relief application requirements helps improve plant
operating efficiency.
Lower valve weight compared to spring loaded valves of
same size improves handling.
