How does XV valve work?
How does XV valve work?
An XV valve is an in/off valve mainly used to provide tight closing conditions (TSO). They can be operated by solenoids (if used in ESD locks) or manually. To do this, a control valve is necessary for discharge of the pump to the bottom of the vessel.
What is a Fisher control valve?
Fisher Control Valves, known for performance and reliability The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keeps the regulated processRead More… variable as close as possible to the desired set point.

Why SOV is used in control valve?
When SOV is in de-energized condition then output is connected with vent (Exhaust port) and its venting the control valve air from exhaust port quickly and moving the valve to the fail-safe position.
What are isolation valves used for?
An Isolation Valve is used in fluid management to stop the flow of process fluids in a pipeline, this is usually for maintenance or safety purposes. They can also be automated to provide flow path selection to change the flow path in a continuous or batch process.
What is Zso and ZSC?
ZSC. Position/unit switch closed. Limit switch indicating a valve is closed. ZSO. Position/unit switch open.
What is P & ID What are its uses and significance?
P&IDs are a schematic illustration of the functional relationship of piping, instrumentation and system equipment components used in the field of instrumentation and control or automation. They are typically created by engineers who are designing a manufacturing process for a physical plant.
What is SOV instrument?
Solenoid operated valves use an electrical coil to control the position of a poppet, plunger or spool to open or close a valve. Typical solenoid control voltages are 12VDC, 24 VAC/DC, 120VAC or 240VAC.
