Valve Size does matter

Size and weight form the key components in dealing with a valve in offshore applications. Whenever control experts discuss issues of control valve sizing, they are talking about the complete process of choosing the right valve suitable to implement a perfect job of controlling the process. Thus, choosing the right valve size is crucial to the process among other similarly important concerns.

The size and weight of an actuator is a big challenge for users of offshore facilities since they are comparatively a small percentage of the total size or weight envelope of the outer cover facility. The enormous weight and considerable size of can be reduced by cutting down on the size and weight of the envelope. Reducing the size and weight of the envelope will have a great impact on the tonnage by almost 50% of the actuator weight and size. The size issue, apart from  the sheer dead weight, the impact can be felt in another area of the application process including structural members, piping runs, skid packages and deck layout among other. By extension, cutting down on weight and size will improve project implementation including hull weight, buoyancy and mooring costs.

 To achieve project implementation efficiency, there is need to reduce size and weight to save costs and improve safety and quality. The key to achieving optimum size lies in the design and materials used for the actuator. When a lightweight material is used for the outer covering, considerable weight reduction can be achieved. If this is integrated with equally lightweight material for the internal construction (actuator), a lighter size product can be produced without sacrificing important features of the product.

Every organization must put their resources to work to achieve a lighter material without losing efficiency. The size of the valve must be proportionate to the size of the project. Where the valve is too small in size, the difference will be obvious and will not meet the flow required, but this is not the case with oversize valves. In any case, it is rare to have undersize valve as there are oversize ones.

In term of costs, the oversize valves cost a considerable amount of money when you factor the cost of procuring it, haulage and other related costs. The sensitivity of a bigger size valve will be obvious in the structural setting and cause considerable changes in flow. Such changes will adjust the required flow of the system impossible.

Selecting the type of valve to use is a highly subjective matter unless there is a specified valve or plant preference to use as a guide. But considering the importance of having the correct size valve and weight in the production process, it is expedient for people in charge of material procurement to understand what is needed and send the right information to the manufacturer or supplier agent to make available the correct specs. There is a need for a regulated approach to choosing a control valve ideal for your application.

Valve Size does matter


It is onus upon people with planning and implementation oversights to come up with the best valve selection approach that will be ideal for the peculiar needs of their organization. It is obvious however to note that valves’ sizes and weights matter on the outcome of your project.
