Signature Series Valves
Metal and Ceramic Seated Ball Valves featuring patented sealing technology.
Taking Sealing to its Practical Limits
The Signature Series Valve represents the State of the Art in Ball Valve Technology. The Signature Series Valve was engineered for lethal environments such as Phosgene where zero leakage is an absolute requirement.

Signature Series Features
- Computer optimization guarantees the best possible design for a given envelope. The in-house developed optimization software ensures a maximum Cv while balancing user requirements against ANSI codes and 25 years of ball valve design experience.
- CoorsTek TTZ Ceramic ball and seat provide outstanding strength and are inert to many lethal chemicals including phosgene. Extensive research in the design of valve balls with Coors Ceramics Company evolved into the current design criteria we employ for all our ceramic trim.
- Optional high alloy trim when ceramic is inappropriate.
- A Patented Sealing Stem eliminates leaking through the stem area. The Signature Series Valve has been tested with no packing in place to validate the integrity of the Patented Sealing Stem.
- The mate lapped ball and seats are tested with both low pressures and high pressure gasses. NDE of the sealing surfaces are performed in addition to the pressure testing before the valve is fully assembled. Every valve is tested after final assembly to ensure a perfect zero-bubble leak every time.
- A unique floating ball design allows bi-directional bubble-tight sealing even during flow reversal.
- SST valves have been in operation for over a year in a phosgene environment. We have one of the worlds first high pressure (1500# Class) ceramic ball valves in operation today.
