Customer Review
  • We started working with SIO in the beginning of 2013, trading thousands of valves during these 2 years.
    During all this time we received from them a lot of concern regarding our need as well as the high quality of the valves we received.
    Their quality is very reliable and the finishing of the product is superb.
    I do really recomend SIO as a reliable partner.

  • During 2014 we opened business discussions with you, and we might say some other companies to buy SS316 Ball Valves which also had to have SS316 grade handles, both lever and tee types, both blue and yellow handles for gas. The price was not the cheapest with Sio, but you agreed to supply to us with the SS316 handles and in the relatively small order quantities that we needed to afford the initial shipment. The deposit was paid and the production commenced, the goods arrived by sea freight and we are very impressed with the standard of the OEM packaging, each valve is packed within a clear plastic bag which is the transparent OEM label, then two valves packed within a white box. The presentation of the product is excellent and the quality of the valves excellent.
