Control Valve 2 Ways Modulating Pneumatic PN16 – GENEBRE

The 2-way modulating pneumatic valve consists of a single seat globe valve piloted by a
simple effect pneumatic actuator (supplied in Normally Closed fail safe position). The
position of the valve plug is regulated by the pressure of the air signal on the membrane
of the actuator. The globe valve can also be used as a cut-off valve (seal).

2 ways modulate pneumatic valve

• Body: carbon steel WCB.
• DIN PN 16 flange ends.
• Seat material: PPL.
• Working temperature -20ºC/+230ºC

The control valve plays an important role in the loop adjustments, in the automatic control of industrial processes. Performs the function of varying the flow of control fluid, which modifies the value of the measured variable, behaving like a continuously variable area orifice. Within the control loop is as important as the primary element, the transmitter and controller. The shutter control performs the function of fluid flow, acting in the direction of its axis. Shutter equal percentage: In a shutter with equal percentage characteristic, every increment of stroke in the shutter produce a change in the flow that is proportional to the one that flowed before the change.

Gaskets are used isopercentual valves for:

• Fast processes.
• When the system dynamics are not well understood.
• When you need high range flow control (rangeability)

The “Rangeability” or field of flow control that valve is capable to regulate maintaining the inherent characteristic curve.
