Smart valve positioner, straight stroke, single acting, failsafe, stainless steel corrosion-resistant
The pneumatic components of the TROLEO series intelligent valve positioner use the 3/3 pneumatic slide valve with independent intellectual property rights, which is characterized by low requirements for compressed air quality and strong resistance to dust, moisture and oil pollution at the application site; easy to achieve single and double-acting control. ;Low static gas consumption; No need for external power loss protector and solenoid valve to achieve three-break fault locking; fast response speed and precise adjustment.
