There are several things to consider when choosing an ever valve. For one, larger valves are typically more expensive and may be difficult to source. Another factor to consider is the weight. Large valves are also difficult to machine in-house, so they are often outsourced. However, when you outsource the production, you are taking a risk that the raw material prices will swing in one direction or another during the duration of the project.
Larger valves are a growing trend in many industries, including the oil and gas, water, chemical, mining, and refining industries. But manufacturing large valves is not easy and only a few companies are up to the task. That’s where VMA member companies such as DeZURIK come in. They answer your questions and address the unique challenges in making large valves.
Generally, a bigger valve allows more air flow at lower lifts. This find out is essential for low-end torque. However, high flow at the top of the lift is only a part of the equation. While a bigger valve can provide better low-end torque, it also decreases valvetrain loads. That’s because the seat and bowl become the bottlenecks for most of the lift. The bigger valve will allow the valve to spend more time in the lower lift regions instead of just going up and down.
As population growth accelerates in arid climates, the need to transport more water through larger pipelines increases. Additionally, groundwater pumping limits are being put in place to prevent seawater encroachment. These challenges, combined with the aging infrastructure of many cities, are increasing the need for bigger valves.
Problems with psi
If you have frequent plumbing repairs, it may be time to check the water pressure in your home. High water pressure can damage your fixtures. Ideally, your water valve should be able to handle 80 psi or less. Higher pressure can cause parts to wear out faster.
Cost of repairing a large valve
The cost of repairing a large valve can vary widely. The price of the repair depends on several factors. For example, repairing a valve can be more costly if the valve is exotic. However, it may be more economical if the valve is made of a common material. The repair process normally includes several inspections of the key valve components. In addition, the process involves extensive documentation and paperwork. As a result, the process is time-consuming, and the cost of repairing it is greater than if the valve were simply a “clean-up and retest” repair.
The time required for a large valve repair varies, from a few minutes to a few days. The time required is dependent on the repair shop and the degree of damage that the valve has received. The repair process is complicated if there is other damage or the valve needs to be replaced with a new one.
