Valve Positioners

Samson valve positioners are crucial components in the field of process control and automation. These devices play a vital role in ensuring precise control of valves used in industrial processes, such as those found in chemical plants, refineries, power plants, and other manufacturing facilities. Samson valve positioners operate based on the principle of comparing the actual valve position with the desired setpoint. They receive a control signal from a process controller, typically in the form of a pneumatic or electrical signal. The positioner then adjusts the valve actuator to achieve the desired valve position, ensuring precise control over the process parameters.

Frequently Asked Questions

Control Valve Accessory FAQs

A positioner is a device used in industrial automation to precisely control the position of valves, actuators, or other mechanical devices. It typically consists of a sensor, a controller, and an actuator. The sensor measures the current position, which is compared to the desired position set by the controller.

Inductive limit switches are sensors that detect the presence or absence of metallic objects without physical contact. In pneumatic control valves, they are utilised to signal valve positions. These switches generate a magnetic field, and when a metallic object (such as a valve stem) enters this field, it induces a current, signaling the switch to change state.

A solenoid valve is an electromechanical device used to control the flow of fluids, such as water, air, gas, or oil. It consists of a coil of wire (solenoid) surrounding a movable ferromagnetic core (plunger) that is connected to a seal or valve mechanism.

Yes, inductive limit switches for pneumatic control valves are designed to function effectively in all general industrial applications. Their robust construction allows them to withstand harsh conditions such as temperature fluctuations, dust, and vibration commonly found in industrial settings.

Positioners offer several benefits, including improved accuracy, increased efficiency, and reduced maintenance. By precisely controlling the position of valves and actuators, positioners can ensure that processes operate at optimal levels, leading to higher productivity and quality. Additionally, positioners can help reduce wear and tear on equipment by minimising unnecessary movements, thereby extending the lifespan of industrial machinery.

Absolutely. These switches are versatile and can be used with both linear and rotary control valves. They come with attachment methods that facilitate their installation and operation on different types of valves, ensuring compatibility across various valve configurations.

Heating, ventilation, and air conditioning (HVAC) systems for regulating the flow of air or refrigerant.

When choosing a positioner, it's essential to consider factors such as the type of valve or actuator being controlled, the required positioning accuracy, environmental conditions, and compatibility with existing control systems. Additionally, factors such as response time, communication protocols, and power requirements should also be taken into account to ensure the selected positioner meets the needs of the application effectively.

The versions with Foundation Fieldbus offer advanced communication capabilities and diagnostics, enhancing control system functionality. Diagnostic features such as partial stroke test (PST), movement counter, operating hours counter, dead time, and transit time measurement provide valuable insights into valve performance and facilitate predictive maintenance.

Fluid compatibility, pressure and temperature ratings, flow rate requirements, environmental conditions.

The partial stroke test (PST) feature allows operators to test a portion of the valve's stroke without fully actuating it. This capability enables routine testing of valve functionality while the system remains operational, minimizing downtime. PST helps identify potential issues with valve operation and ensures that the valve responds as expected in critical situations.
