Advantages

The Masoneilan 31000 Series control valve is an eccentric plug control valve lined with PFA, specifically designed for corrosive applications and featuring the following attributes:

Outstanding Performance:

The eccentric rotary plug configuration ensures superior throttling control precision, minimal dynamic forces, and effective sealing. Its straight-through flow design facilitates high flow rates.

 

Corrosion Resistance:

The PFA lining of the Masoneilan 31000, which maintains a guaranteed minimum wall thickness, offers robust protection against a wide range of corrosive substances.

 

Minimized Fugitive Emissions:

The rotary mechanism significantly lessens wear on the packing compared to conventional linear valves. Furthermore, the standard configuration includes PTFE/Graphite packing and chevron rings, supported by a double O-ring follower to enhance reliability in corrosive environments.

 

Simplified Maintenance:

The valve’s compact size and lightweight construction enable straightforward installation and removal, without imposing additional stress on the piping system.

 

Dependability:

Dovetail grooves create a mechanical bond between the metal body and the PFA lining, ensuring optimal performance under vacuum conditions and elevated temperatures. The reliable, field-tested rolling diaphragm actuator guarantees a positive fail-safe mechanism. The actuator linkage is fully enclosed and features a combination handwheel with an adjustable limit stop and locking system. A comprehensive range of options and accessories is available for all actuators.
