The Keystone brand is a recognized world leader in butterfly valves and industrial process valves. Keystone designs developed a strong reputation for reliability, quality and service. These attributes have been nurtured by Pentair 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 brand we designed and 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.
