2inch MULTISTEP VALVE ISOIL A1B1C1D1E1F2

Descripción

One of the main features of the ISOVALVE automatic valve is that it uses the pressure of the fluid passing through it, to perform the functions which it has been designed for. The valve shutter is driven by the movement of the diaphragm, actuated through the energy of the process.

Operation
The valve operation is obtained by 2 Ex (24 VDC / 115-230 VAC) solenoid valves one of them normally opened (NO) and one normally closed (NC). Tipically the valve would be situated just downstream of the meter on tank truck loading terminals or transfer pipelines of petroleum or chemicals.

Functions
The valve control circuit may be configured in different ways in order to get several function, with the same kind of valves, as follows:
» non return identificated by (R)
» flow limiting identificated by (L)
» 1 or 2 step closure/opening identificated by (1S or 2S)
» Multistep closure/opening
On request:
» driven by pneumatic solenoid valves (P)
» pressure reducing identificated by (RID)
» differential identificated by (D)
» calibrated flange identificated by (FT)
» special execution for LPG
