    We are Keystone Steam Supplies, a steam & hydronics wholesaler in Canada. However, we are not the manufacturer of Keystone Valves. Our company name's similarity to the brand is by coincidence only. In particular, if you are from the United States we encourage you to find a direct distributor closer to your location who can offer better assistance.

    While we can quote and sell Keystone Valves, if you are looking for the manufacturer for large-scale requests or technical inquiries, please visit Emerson Automation Solutions - Global Customer Care.
