Marwin Valve's 2-IQ Series Smart Valve Positioners
Marwin's 2-IQ Smart Positioner has superior accuracy, long-term reliability and ease of use. THe unit is available with or without Profibus PA or HART protocols, and is designed so that optional modules for alarms, and positioner feedback are easily plugged in or snapped on.
The unique positioners can give unequalled performance from Marwin ball valves when used for control in a process. The 2-IQ is loaded with many standard features including:
- The ability to change the valve's action at the touch of a button
- Split ranging without changing parts
- Characterization of the flow pattern through the positioner
- Deadband adjustment
- Tight closing feature
Other impressive standard features include loop powered control. There is no need to have a separate power supply as the positioner runs from the signal leads. The 2-IQ will withstand 175°F ambient temperatures and a shock resistance of 10g. It has a resolution accuracy of <0.05%.
Marwin Valve offers the 2-IQ in three primary configurations:
Basic Versions: a smart positioner without gauge, HART protocol or hazardous location approvals.
Standard Version: Same basic unit but with HART protocol, gauge and FM Approval (IS) for Class I, Div. 1 locations.
Other configurations upon request from factory.
