high quality Samson 3767 Pneumatic Control Valves Positioner with Pressure regulator

Product Description:

The positioners play a crucial role in ensuring precise control of valves in industrial applications. They facilitate a predetermined assignment of valve position, which is the controlled variable x, to the reference variable w, which is the input signal.

To achieve the desired valve position, the positioner compares the input signal, received from the control system, to the travel of the control valve. Based on this comparison, the positioner issues a corresponding output signal pressure, pst, which is the output variable y.

In applications where double-acting actuators are used, a reversing amplifier is used to produce two opposed signal pressures. This ensures that the valve's position can be precisely controlled in both directions of movement.

Features:

The product boasts a range of mounting positions, suitable for both normal and split-range operations. Its dynamic response is excellent, with an almost negligible effect on the supply air. Additionally, the proportional band (P band) is adjustable, as is the air output capacity. The compact design requires very little air supply consumption and is highly insensitive to mechanical vibrations, helping to reduce the need for maintenance.

For use in hazardous areas, there are versions with intrinsic safety II 2G Ex ia IIC T6 or II 3G Ex na II T6 for Zone 2. Alternatively, the product is available with "Flameproof enclosure" Ex d for use with a Type 3766 Positioner and Type 6116 i/p Converter (Fig. 2). It can also be directly attached to a Type 3277 Actuator (Fig. 3), or attached to other actuators according to IEC 60534-6. Furthermore, it can be attached to rotary actuators according to VDI/VDE 3845.

Applications:

Single-acting and double-acting positioners are two types of devices that can be attached to pneumatic control valves for improved performance and control.

A single-acting positioner uses air pressure to move the valve actuator in one direction, while a spring returns it to its original position when the air pressure is released. On the other hand, a double-acting positioner uses air pressure to move the valve actuator in both directions.

Both types of positioners can offer precise control over valve actuation, allowing for consistent and accurate regulation of flow rates and pressure levels in industrial processes. The choice between a single-acting and double-acting positioner will depend on the specific needs of the application, as well as the type of control valve being used.

Overall, the use of positioners can help to optimize the performance of pneumatic control valves and improve the efficiency of industrial processes as a whole.
