The first thing that you should know is that COVNA Valve customer service was of the highest order. The performance of Mrs Fiona Dai who was my contact at COVNA was superb, she answered questions promptly and accepted the level of detail that I required. Mrs Dai’s spoken and written english is polished and she is a tremendous representative for the COVNA and someone we could learn from! So customer service was of the highest standard and it made my purchasing decision much easier. This was backed up by quick responses to challenges regarding a fitting dimension used in Australia versus the standard employed by COVNA. Once the challenge was recognised COVNA immediately volunteered to rectify the difference and did not charge for the rectification or modify the delivery date. I highly recommend COVNA Valves and I will certainly work with their team again without any doubt. I remain very impressed by their service and quality.

And the cost was appropriate.

Pneumatic actuator valves with limit switches or positioners can accept/feedback signals to achieve the purpose of remotely controlling the switch. The positioner can also adjust the switch angle to accurately control the flow.
