The Masoneilan 31000 Series control valve is designed for corrosive applications and features a PFA lining. Key attributes include:
- An eccentric rotary plug that ensures exceptional throttling control accuracy, minimizes dynamic forces, and guarantees tight shut-off.
- A PFA lining with a guaranteed minimum wall thickness, offering resistance to a wide range of corrosive fluids.
- A straight-through flow pattern that facilitates high flow capacities.
- PTFE/Graphite packing with chevron rings, supported by a double O-ring follower.
- Compact size and lightweight design that do not compromise piping forces.
- Dovetail grooves for mechanical anchoring between the metal body and PFA lining, ensuring optimal performance under vacuum and at elevated temperatures.
- A robust, field-tested rolling diaphragm actuator that provides reliable fail-safe action.
