Smart valve positioner, intrinsically safe explosion-proof Exia, straight stroke, single acting, failsafe, stainless steel corrosion-resistant
In industrial field, some special applications require interlocking control. When the valve is fully open or closed, or the preset valve position, the DCS system needs to collect the switching value of the corresponding position of the valve position to start the special security control or linkage control. The traditional method of this function is that on the basis of the positioner, the valve is externally connected with a valve position mechanical contact sampler, which is connected with the actuator movement mechanism of the valve to obtain the corresponding valve position switching value. Top-5879f1 series are basic and intrinsically safe products with unique structural design. The built-in valve position upper and lower limit contact output module is an option. Users who need this function can easily implement it without any external devices.
