2) FMTD64-U Forbes Marshall Universal Thermodynamic Trap
The Forbes Marshall Universal Thermodynamic Trap, FMTD64- U, is a stainless steel thermodynamic steam trap with integral strainer. All FMTD64-U traps are fitted by two screws to a pipeline connector to ensure the maintenance is quick and easily undertaken. Traps can be removed / replaced using a simple wrench with minimum system downtime.

3) FMTD65-B, FMTD65-A
Forbes Marshall Thermodynamic Trap with Blowdown Valve and/or Anti-Airbinding Disc The Forbes Marshall Thermodynamic Trap with blowdown valve, FMTD65-B, is a mainline thermodynamic trap with inbuilt strainer screen and unique three port design. The three port design ensures parallel lifting of the disc and no wear and tear due to uneven seating of the disc enhancing the life of the trap. Integral blowdown valve allows online cleaning of strainer screen. Typical applications include main distribution headers, tube line inlets etc. During start up air is trapped in the control chamber of the trap. Being air, it cannot condense and hence the pressure will not drop. This causes the trap to fail in closed condition. FMTD65-A is specially designed to overcome this air binding problem. It is a trap with a 0.8 mm perforations stainless steel screen and a special anti-air binding disc. Sizes and Connections DN 15 and DN 20 Screwed BSPT/NPT/BSP and socket weld ends with blowdown valve. Available with Class -150, 300 and 600 weld on flanges on request. Available with IBR certificate.

4) FMTD76-M Forbes Marshall Thermodynamic Trap
