Keystone is a recognized world leader in butterfly valves and industrial process valves.
Originally designing, patenting and introducing the Butterfly Valve in 1951, Keystone developed a strong reputation for reliability, quality and service. These attributes have been nurtured and have stayed with the brand as the portfolio was increased to include the Keystone pneumatic and electric actuators and controls which give our valve packages seamless compatibility and the owners a single point of contact for package responsibility. Also carrying the Keystone name we produce a range of knife gate valves and ball valves. These products offer the customer the same solid performance and low cost of ownership as our market leading butterfly valve range.
