Types of Valves Offered

When we talk about valves, it's not a one-size-fits-all situation. Dally Engineering likely offers a wide array of valve types to cater to different industrial needs. Let's break down some of the most common ones:

Ball Valves

Ball valves are quarter-turn, on-off valves that use a hollow, pivoting ball to control flow. The ball has a bore through the center, which, when aligned with the pipe, allows flow. When the ball is rotated 90 degrees, the bore is perpendicular to the pipe, blocking flow. Ball valves are known for their quick operation, tight shutoff, and durability. They are commonly used in applications where fast and reliable shutoff is required, such as in chemical processing, oil and gas, and water treatment. Dally Engineering likely offers ball valves in various materials, such as stainless steel, carbon steel, and brass, to suit different media and operating conditions. They may also provide different end connections, such as threaded, flanged, and welded, to facilitate easy installation.

• Advantages of Ball Valves:
  • Quick and easy to operate
  • Tight shutoff
  • Durable and reliable
  • Relatively low cost
• Disadvantages of Ball Valves:
  • Not suitable for throttling flow
  • Can trap fluid in the ball cavity

Gate Valves

Gate valves are linear motion valves that use a gate or wedge-shaped disc to control flow. The gate is raised or lowered to open or close the valve. Gate valves are primarily used for on-off service and are not suitable for throttling flow. They offer minimal pressure drop when fully open, making them ideal for applications where unrestricted flow is desired. Gate valves are commonly used in pipelines, power plants, and water distribution systems. Dally Engineering likely offers gate valves in different configurations, such as rising stem and non-rising stem, and with various bonnet designs, such as bolted bonnet and pressure seal bonnet. They may also provide gate valves with different trim materials to enhance corrosion resistance.

• Advantages of Gate Valves:
  • Minimal pressure drop when fully open
  • Suitable for high-pressure and high-temperature applications
  • Relatively simple design
• Disadvantages of Gate Valves:
  • Slow to operate
  • Not suitable for throttling flow
  • Can be prone to vibration and wear

Globe Valves

Globe valves are linear motion valves that use a disc to regulate flow. The disc moves perpendicular to the flow path, allowing for precise throttling. Globe valves are commonly used in applications where flow control is critical, such as in chemical processing, power generation, and HVAC systems. They offer good shutoff capabilities but have a higher pressure drop compared to gate valves. Dally Engineering likely offers globe valves in different body patterns, such as straight pattern, angle pattern, and Y-pattern, to suit different piping configurations. They may also provide globe valves with different disc designs, such as ball disc, composition disc, and plug disc, to optimize flow characteristics and shutoff performance.

• Advantages of Globe Valves:
  • Excellent throttling capabilities
  • Good shutoff performance
  • Suitable for high-pressure applications
• Disadvantages of Globe Valves:
  • Higher pressure drop compared to gate valves
  • More complex design than gate valves

Check Valves

Check valves are one-way valves that allow flow in only one direction, preventing backflow. They operate automatically, without the need for manual intervention. Check valves are commonly used to protect pumps, prevent siphoning, and maintain pressure in pipelines. They are essential components in many industrial systems. Dally Engineering likely offers check valves in various designs, such as swing check, lift check, and ball check, to suit different applications and flow conditions. They may also provide check valves with different seating materials to enhance sealing performance.

• Advantages of Check Valves:
  • Automatic operation
  • Simple and reliable design
  • Prevents backflow
• Disadvantages of Check Valves:
  • Can cause pressure drop
  • May be noisy in certain applications

Butterfly Valves

Butterfly valves are quarter-turn valves that use a disc to control flow. The disc is positioned in the center of the valve and rotates to open or close the valve. Butterfly valves are lightweight, compact, and offer good flow control. They are commonly used in water treatment, chemical processing, and HVAC systems. Dally Engineering likely offers butterfly valves in different types, such as wafer type, lug type, and flanged type, to suit different piping connections. They may also provide butterfly valves with different disc and seat materials to enhance corrosion resistance and sealing performance.

• Advantages of Butterfly Valves:
  • Lightweight and compact
  • Good flow control
  • Relatively low cost
• Disadvantages of Butterfly Valves:
  • Higher pressure drop compared to gate valves
  • Not suitable for high-pressure applications

Choosing the Right Valve

Selecting the correct valve is crucial for optimal performance and safety. Here are some key factors to consider:

Material Compatibility

The valve material must be compatible with the fluid being handled to prevent corrosion, erosion, and contamination. Consider the chemical properties of the fluid, including its pH, concentration, and temperature. Common valve materials include stainless steel, carbon steel, brass, PVC, CPVC, and various alloys. Dally Engineering likely offers valves in a wide range of materials to suit different applications.

Pressure and Temperature Ratings

The valve must be able to withstand the maximum pressure and temperature of the system. Exceeding the valve's pressure or temperature rating can lead to failure, resulting in leaks, damage, and potential safety hazards. Check the valve's specifications to ensure that it meets the requirements of the application. Dally Engineering probably provides valves with different pressure and temperature ratings to accommodate various operating conditions.

Flow Rate and Pressure Drop

The valve must be able to handle the required flow rate without causing excessive pressure drop. A high pressure drop can reduce system efficiency and increase energy consumption. Consider the valve's flow coefficient (Cv), which indicates its flow capacity. Dally Engineering may offer valves with different flow coefficients to optimize flow performance.

Actuation Method

Valves can be actuated manually, electrically, pneumatically, or hydraulically. The choice of actuation method depends on the application requirements, including the need for remote control, automation, and speed of operation. Manual valves are simple and cost-effective but require manual operation. Electric, pneumatic, and hydraulic valves offer remote control and automation capabilities. Dally Engineering likely provides valves with different actuation options to suit various control needs.

Industry Standards and Certifications

Ensure that the valve meets relevant industry standards and certifications, such as ANSI, API, ISO, and ASME. These standards ensure that the valve has been tested and certified for safety, performance, and reliability. Certifications provide assurance that the valve meets specific requirements and is suitable for the intended application. Dally Engineering probably holds certifications that demonstrate its commitment to quality and compliance.
