Product Description

Samson 3730-1 2 3 Electro-Pneumatic Positioner for Pneumatic Valve

Product Introduction

The positioner ensures a predetermined assignment of the valve position (controlled variable x) to the input signal (set point w). It compares the input signal received from a control system to the travel or rotational angle of the control valve and issues a corresponding output signal pressure (outputvariable y).

- In case of Fail Freeze or Fail Safe optional product, it maintains the current valve position without any additional equipment such as lockup valve or solenoid valve in case of power supply (24V) failure.

- Back light function LCD is attached so you can check the status of the positioner directly in the field.

- Four adjustment buttons and unique functions of the buttons are applied in the same way throughout the firmware, so it is very easy to use.

- The initialization time is very short, which minimizes the change of valve stroke in case of temporary power failure and improves system stability.

- Very strong against vibration and can be used in extremely high vibration areas.

- The change in supply pressure during use has almost no effect on the adjustability of the positioner.

- Auto calibration is very simple, so first time users can handle the product easily.

- Compact size makes it easy to attach to small actuators.

- Very low air consumption which allows large plants to reduce their operating costs.

- The valve system can be stabilized by outputting an analog feedback signal.

- Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and User Set which user can make 5 points or 21 points characterizations.

- You can minimize valve leakage by setting the sealing function of Tight Shut-Off / On.

- Half-interval control (Split Range) is available such as 4 ~ 12mA and 12 ~ 20mA etc..

- You can change Zero and Span freely through Hand Calibration function.

- By manual operation, valve can be operated arbitrarily irrespective of input signal, so it is easy to judge whether or not there is an abnormality of valve.

- Ingress protection of IP67.

- The product's enclosure is made of a material with excellent chemical resistance and moisture resistance, so it can be used stably for a long time even in a corrosive atmosphere.

- The internal structure is very simple and modular, so there is little possibility of failure and maintenance is simple.

- It is equipped with a foreign material prevention filter which is easy to maintain.

- Flow rate can be selected according to actuator size.

- Solenoid valve with superior durability of over 200 million cycles.
