Enpro Systems custom designs and manufactures a complete line of high temperature butterfly valves for Flue Gas and Power Recovery Systems. Enpro Valves are provided with Electro-Hydraulic, Pneumatic or Electric Actuators.
Our stringent engineering evaluation incorporates the following design features in all Enpro Butterfly Valves:
Critical material selection and design clearances withstand upset conditions and temperature excursions. 
Heavy duty construction resists distortion under severe operational loads and temperatures.
Critical valve control points are protected from abrasive catalyst fines.
All valves are designed to resist dynamic flows and accelerated closures during upset or emergency conditions.
The result is a custom design, tailored to your individual requirements, providing trouble free operation and unmatched service life. Our butterfly valve applications include:
Expander By-pass Valves
Flue Gas Block Valves
CO Boiler Diverter  

 

 
With Enpro offering all of the fabrication of FCCU Slide and Butterfly Valves within its own facility, all quality and delivery is controlled within Enpro and not subject to unregulated outside manufacturing.

We also provide refractory installation and curing for all valves and most
equipment manufactured. Enpro submits refractory installation procedures and works with all customer specifications with our own in-house technicians
No other FCCU Valve manufacturer maintains the ASME and NBBI certifications that we do. This ensures our customers that when they require manufacturing in accordance with ASME, Enpro can provide it as a real function supported by an ASME certified quality control program. Our quality program is based on ISO-9000.
Enpro's technical personnel will visit your plant prior to shutdown to discuss possible work for the valves.

We will evaluate your last repair and make any necessary recommendations to extend the life of your valves.
