What does the actuator VL Cylinder from Foss Valves represent?
Thread Content
The Fox valves represented by the company are of the Mark One type, with a size of 4.00, pressure rating of CL 1500, made of carbon steel (WCC), and equipped with P/B O-rings. They belong to the MegaStream series; the actuator used is a VL cylinder. The positioner used is of the Logix 500 + Series type, with model number 520MD+37-W1D300-GM3-0000. Does the value 4.00 refer to 4 inches? Also, what does VL Cylinder refer to? What does VL mean? Does any expert know?
It has been confirmed that 4.00 refers to 4 inches; it’s just not clear whether VL Cylinder means a rodless cylinder
