Emerson Keystone™ Isolation Valves
Meeting the Needs of the Process Industries Since 1951
Keystone built its reputation by providing industrial process butterfly valves known for their reliability, long service life, and reduced operating costs.
These products were previously part of the Tyco and Pentair offerings. Thankfully these quality products now complement and enhance the Emerson offering making us your single source provider.
Independent life-cycle testing shows that Keystone resilient-seated butterfly valves last 2.5 times longer than competitors’ comparable butterfly valves.
Keystone offers fully integrated valve packages for exceptional performance.
Keystone valves include:
- Resilient Seated Butterfly Valves with unique resilient seating designed to seal around the disc, isolating the valve body and stem from the line media.
- Keystone High Performance Butterfly Valves are engineered with K-LOK polymer and elastomer seats which provide bi-directional, drip-tight closure in vacuum as well as at full rated differential pressure. This unique design seals at high and low pressures (as well as in dirty service) without pressure assistance. The extended neck on Keystone High Performance Butterfly Valves provides additional insulation. Assembly and installation is simplified with an integrated mounting pad for direct mounting of many actuator types,
- Knife Gate Valves for light to medium slurry applications in mining and mineral processing, power, pulp and paper, chemical and waste water applications
