Product Selection Differences for Energised Valve Systems

When selecting Energised Valve Systems, there are several key differences to consider:

  1. Valve Type:

    • Ball valves, butterfly valves, gate valves, globe valves, and check valves are common types used in energized valve systems. The selection should be based on the specific application requirements such as flow control, pressure rating, and service conditions.

  2. Actuation:

    • Energised valve systems can be actuated using different methods such as manual operation, pneumatic actuation, electric actuation, or hydraulic actuation. The choice of actuation method depends on factors like automation requirements, operating conditions, and control systems compatibility.

  3. Sealing Technology:

    • The sealing mechanism plays a crucial role in the performance of energised valve systems. Options include soft seat (elastomer) seals, metal-to-metal seals, and graphite seals. The selection should be based on factors like temperature, pressure, and compatibility with the media being controlled.

  4. Material of Construction:

    • The material of construction for valve components is essential for durability, corrosion resistance, and compatibility with the process fluid. Common materials include stainless steel, carbon steel, brass, and exotic alloys. Consider the application requirements to choose the appropriate material.

  5. Pressure and Temperature Ratings:

    • Understanding the pressure and temperature limitations of energised valve systems is crucial to ensure safe and reliable operation. Select valves that can handle the maximum pressure and temperature conditions of the application.

  6. Flow Characteristics:

    • Different valve types offer different flow characteristics such as linear, equal percentage, or quick opening. Consider the flow requirements of the system to select the valve design that best suits the process control needs.

  7. Certifications and Standards:

    • Check if the energised valve systems meet industry standards and certifications like API, ANSI, ISO, and others. Compliance with these standards ensures quality, reliability, and safety of the valve systems.

By carefully evaluating these key differences and aligning them with your specific application requirements, you can choose the most suitable energised valve system for your needs.
