Product Selection Differences for Pneumatically Actuated Control Valves

When selecting Pneumatically Actuated Control Valves, there are several key differences to consider:

1. Valve Type:

   • Globe valves: provide good control performance and are suitable for throttling applications.
   • Ball valves: offer fast operation and tight shutoff, but may not provide precise control.
   • Butterfly valves: offer a compact design and low pressure drop, suitable for larger flow applications.

2. Actuator Type:

   • Piston actuators: provide high thrust and accurate control, suitable for high-pressure applications.
   • Diaphragm actuators: offer good control performance and are suitable for applications with smaller valve sizes.
   • Rotary actuators: used for ball and butterfly valves, providing quick operation and tight shutoff.

3. Control System Compatibility:

   • Consider compatibility with your existing control system, such as pneumatic, electric, or digital control systems.

4. Valve Size and Flow Capacity:

   • Select a valve size based on your flow requirements and ensure it can handle the maximum flow capacity needed for your application.

5. Material of Construction:

   • Consider the material of the valve and actuator based on the process fluid, pressure, and temperature conditions to ensure durability and longevity.

6. Installation and Maintenance:

   • Evaluate ease of installation, calibration, and maintenance requirements of the valve to optimize your operational efficiency.

7. Control Performance:

   • Look for valves with precise control characteristics, minimal hysteresis, and fast response times for optimal process control.

Consider these factors to make an informed decision when selecting Pneumatically Actuated Control Valves for your specific application.
