Quarter-turn valves have been gaining traction lately due to their ability to offer superior performance and reliability compared to the traditional gate or globe valves. Their compact design allows them to be used in tight spaces while providing a reliable seal, making them an increasingly attractive option for applications ranging from water treatment plants, oil & gas pipelines, chemical processing plants, and more.
Discover the potential of using quarter-turn valves today and learn why they become the valve of choice!
Are Quarter Turn Valves Better?
Quarter-turn valves are often better than traditional multi-turn valves because they require less time and energy. They also have a longer lifespan, with tests showing that quarter-turn valves can last up to 10 times longer than traditional ones. Additionally, they offer more precise control over the flow of fluids since their rotary actions allow for incremental changes in the degree to which they open or close. This makes them ideal for applications where exact flow control is needed.
Introduction to Quarter Turn Valves
Quarter-turn valves are a type of valve that uses handles, levers, or actuators to control fluid flow. They are commonly used in various industries and applications, including gas, water, and oil pipelines. Quarter-turn valves are generally preferred over other valves due to their ease of use and reliability.
Unlike traditional linear motion gate or globe style valves, which require several turns to open/close, quarter turn valves can be opened or closed quickly by simply turning the handle 90 degrees.
This makes them ideal for fast response systems where quick action is required, such as emergency shut-offs in water supply lines. Additionally, they require less maintenance than traditional linear motion designs since fewer parts are involved in operation than multi-turn designs.
The most common quarter-turn valve design is the ball valve which uses a floating sphere with one port opening at its center point for controlling the flow rate when turned on/off (1/4th revolution).
These are popular due to their improved accuracy when controlling flow rate compared with other valves. Furthermore, ball valve designs typically have lower installation costs than many competing products due to having fewer components involved in installation processes, such as gaskets and flanges not needed with this design type.
Overall, quarter-turn valves offer superior performance benefits over a traditional gate or globe-style valves, especially when it comes ease-of-use and reliability, making them suitable for many industrial applications requiring quick response times while still maintaining an acceptable level of accuracy when controlling fluids such as gas or liquids within pipelines
Advantages of Quarter Turn Valves
Quarter-turn valves, also known as quarter-turn actuators, are a type of valve that offers several advantages when compared to other types of valves. Quarter-turn valves can be used in many industrial and commercial applications due to their unique design, allowing for quick open/close operation with minimal effort.
Here are some benefits of using quarter-turn valves:
- Versatility – Quarter turn valves can be used in various situations since they come in different sizes and materials to handle any pressure or temperature regulation needed.
- Durability – The metal components that make up the valve structure are designed to withstand harsh conditions, such as extreme temperatures and high pressures, without corroding or rusting over time.
- Efficiency – Since opening and closing the valve only requires a quarter rotation, it saves time and energy during operation compared to the traditional linear motion method required by other valves.
- Reliability – Due to their simple yet robust design, these types of valves provide reliable performance with very little maintenance requirements over long periods of use
Disadvantages of Quarter Turn Valves
Quarter turn valves have many advantages, but certain disadvantages must be taken into consideration when deciding whether or not they’re right for the job:
- Limited range of flow patterns – Quarter turn valves don’t allow much flexibility in controlling the flow rate or direction.
- Not suitable for high-pressure systems – Due to the limitation on available pressure ratings with quarter turn valves, they may not be suitable for more demanding applications where higher pressures are needed.
- Potential leak points – The O-ring seals used in some quarter-turn valve designs can become worn over time leading to potential leakage problems if not maintained properly.
- Difficulty operating at low temperatures – At lower temperatures, rubber O-rings become stiffer, making it harder to operate a quarter-turn valve effectively without damaging them from the excessive force being applied during the operation.
Conclusion: Are Quarter Turn Valves Better?
In conclusion, quarter-turn valves are an excellent choice for many applications due to their ease of installation and use. The quick response time to shut-off flow makes them ideal for emergency shutdowns and general on/off operations.
Quarter-turn valves also offer superior construction materials, which provide great durability and longevity in harsh environments. The versatility of the designs allows them to be used in both low-pressure and high-pressure systems with various connection types available.
These features make the quarter-turn valve an attractive option when selecting your next valve system.
