BI-EXCENTRIC BUTTERFLY VALVE – TCL Steam, Sanitation and Miscellaneous Processes. For blocking and control applications, with 2 displacements.
CHECK VALVE with quick closing Assisted by an Actuator for installation in the extraction of steam turbines, designed to have the lowest possible head loss for a given flow, guaranteeing better machine performance, and making its closing instantaneously.
ANGULAR STEAM DESUPERHEATER VALVE TCL DS4 has opening and closing by pneumatic piston actuator designed to ensure the best performance of the valve. Radial-bored desuperheater nozzles introduce highly atomized water droplets into a fan-shaped rotational motion of the steam flow, eliminating the need for a water control valve. Designed for pipes from 6 to 24 inches in diameter.
TRI-EXCENTRIC BUTTERFLY VALVE – TCL with 3 displacements developed to advantageously replace valves with metal seats and valves with elastomer seats, as it has an efficient sealing system that can work at high temperatures maintaining sealing repeatability, and at low temperatures with high durability compared to valves with elastomer seats, it has greater mechanical resistance. Its sealing system with rings in elliptical conical shape with blades fixed to the valve body mounted in an identical solid seat fixed to the disc, which guarantees perfect seating to perform valve sealing.
