What is a Soft Start?
Soft start in a pneumatic circuit is a technical process aimed at gradually increasing air pressure within the system. This method prevents mechanical impacts and shocks that can occur with sudden starts. It enables a controlled and gradual start of pneumatic flow, protecting sensitive components, reducing wear, and enhancing operator safety.
Operating Principle of a Soft Start Valve
A fundamental feature of soft start valves is their pressure control mechanism. During the feed phase, these valves use a shutter to open a limited air passage, introducing controlled air into the pneumatic circuit and ensuring controlled movement of pneumatic actuators. During this phase, an internal passage connects the outlet pressure to the valve's control, and when this pressure reaches approximately 50% of the supply pressure, the valve switches the internal shutter to fully open the passage.
Advantages of Soft Start Valves
The undisputed advantage of soft start valves lies in their ability to prevent uncontrolled movements. The controlled and gradual start reduces the risk of sudden pressure spikes, which can damage pipes, seals, and other system components. This meticulous control helps prevent unexpected service interruptions and reduces the need for costly and frequent maintenance. Additionally, they significantly maximise the useful life of equipment and machinery. By reducing wear caused by abrupt starts and stops, these devices help maintain machines in optimal condition for longer periods. This translates into less need for repairs and replacements, resulting in long-term cost savings for the company.
Main Applications of Soft Start Valves
Due to their simplicity and low cost, soft start valves are used in a wide range of industrial applications.
