Steam distribution manifold
Steam distribution manifold built by welding forged-steel modules with four or six tracer branches. TCMs piston valves with reinforced-graphite sealing rings isolate the individual branches. The modular concept covers arrangements with 4, 6, 8, 10 and 12 steam tracers. The main inlet is 1 1/2-inch socket-weld, tracer connections are 1/2-inch socket-weld or NPT, and the drain connection is 1/2-inch socket-weld. The construction designation is ISO PN50, with a maximum temperature of 400°C and maximum pressure of 32 bar.

Lubricated inverted-plug valve
The lubricated plug valve uses a pressure-balanced inverted tapered plug. Two balancing passages connect the chambers at the ends of the plug to reduce the risk of binding in the body. Shut-off relies on a precisely fitted metal-to-metal interface supported by a lubricant film; lubricant may be injected during operation or shutdown. The anti-blowout stem is separate from the plug, and plug position is adjustable. Applications include fluids containing suspended solids and, with a heating jacket, fluids that must be kept warm. Temperature capability depends on the lubricant, while operating torque and actuator selection depend on the service conditions.

Double-offset butterfly valve
This double-offset butterfly valve combines a profiled disc, extended neck and compact body. The offset disc motion and controlled deformation of the PTFE seal provide bidirectional shut-off while reducing rubbing during opening and closing. Carbon-steel and stainless-steel bodies are described in wafer and lug configurations. The line seal can be replaced without dismantling the disc, while external packing uses an O-ring with graphite backup. The listed size ranges are 3–36 inches for Class 150 and 3–24 inches for Class 300.
