Custom Pneumatic Pressure switch for Safety Valve Application

Client Requirements: A leading customer in the pneumatic safety valve industry had been using a pressure switch that was rated to 1,000,000 cycles. They were looking for an alternative product that is capable of meeting a minimum of 20,000,000 cycles due to new potential regulatory standards. This customer provides their products internationally. As such, they have a high demand for quality and reliability demand in order to meet multiple regulatory standards.
The client also identified that the existing switch could occasionally be misused by customers for which they have seen physical damage to the switch by an excessive external load. As such, they wanted a smaller profile to minimize the potential damage.

Our Solution: Upon identifying the technical parameters required, we designed a robust switch that was capable of exceeding their cycle count requirement. The switch was tested to over 100,000,000 cycles without failure. Instead of using a traditional micro switch-based design, we had designed a custom solid-state unit that resulted in significant functional improvement. The customer was really impressed that Anfield was able to not only meet the technical requirements but also provided a very competitive solution. Additionally, we were able to reduce the overall profile size by 40%. This also enabled them to provide a more compact system to the customer. All custom projects are supervised by our engineers during production rollout to ensure that all requirements are met to desired specifications. Proper protocols are followed to ensure consistent quality of product delivered.
