Valve manufacturers need to select the actuator by measuring the opening and closing torque forces of the valves they design at no load and under load. Actuator selections based only on mathematical calculations without measuring the torque forces required to open and close the valves can be risky. If the torque force is calculated less than it should be or the friction tolerances are not realized as calculated, the power of the selected actuator may not be sufficient. Valves-valves may not open or close under load-pressure. This is a big problem for the customer and a big loss of confidence for the manufacturer.

If the opening and closing torque of the valve is overestimated and an unnecessaryly powerful actuator is selected, unit costs will be high. In such a situation, it will be a factor that reduces the competitiveness of the manufacturer.

The valve sector is a three-legged system. This system consists of the valve manufacturer, the actuator manufacturer and the customer. The expectation of the customer is that the valve system he has purchased can open and close smoothly under load in real life. In order for this system to work smoothly in practice, the valve and the actuator must be compatible with each other. It means that the power of the actuator is strong enough to open and close the valves. The only method to ensure this compliance is the on-off test of the valves.
