TC_Flange – K (Polyamide disc), DN 15 – 200 (½” – 8”) The Thermoclassic Flange-design valve with a plastic disc (K) (TCF- K) is a non-return valve in short design for clamping between pipe flanges. The plastic disc works to maximum of 130°C/266°F, applicable with PN 6/10 according to DIN EN 1092-1. Manufacturer: Reiche, Type: Thermoclassic (TC) F -N.../15-20-25-32-40-50-65-80-100-125-150-200 (DN). Other nominal sizes or flange connections (e.g. ASME, BS or company standards) can be ordered on request.
For silent operating in heating-, hot water- and solar installations. For preventing unintended thermal upthrust. To separate different heating circuits. To prevent reverse circulation. Also available with a lifting device /A.
The internally guided valve plate ensures absolute silence while operating. The mechanical lifting device /A provides deaeration and simplifies the filling and draining of the plant.
It also enables an intended thermal upthrust in case of a breakdown of the circulation pump (max. 130°C / 266°F). Despite the noise-reduced disc-guidance it is possible to design the disc seat with a soft seal /W (max. 130 °C / 266°F).

The internally guided valve plate ensures absolute silence while operating. The mechanical lifting device /A provides deaeration and simplifies the filling and draining of the plant.
It also enables an intended thermal upthrust in case of a breakdown of the circulation pump. The siphon airlock ensures at vertical installation a constant function of the valve, due to continuous venting. This leads to
a smooth operation even after long periods of standstill of the plant.
The breather connection /E allows the adaption of a constant breather for deaerating the system. Other adaptors are also
possible, e.g. a thermometer.

For silent operating in heating-, hot water- and solar installations. For preventing unintended thermal upthrust. To separate different heating circuits. To prevent reverse circulation. Also available with a SOLAR lifting device /A (max. 170°C / 338°F ).
The internally guided valve plate ensures absolute silence while operating. The mechanical lifting device /A provides deaeration and simplifies the filling and draining of the plant. Top temperature
170°C / 338°F. It also enables an intended thermal upthrust in case of a breakdown of the circulation pump.
The siphon airlock ensures at vertical installation a constant function of the valve, due to continuous venting. This leads
to a smooth operation even after long periods of standstill of the plant.
The breather connection /E allows the adaption of a constant breather for deaerating the system. Other adaptors are
also possible, e.g. a thermometer.

Flow optimization through patented double plate construction. The internally guided valve plate grants a minimum of noise. Through the valveʼs particularly flat installation height of 1.5 mm, a fast, affordable and space-saving installation is
ensured when it comes to plant expansions. The unique design of the valve plate allows, if installed vertically, a standard internal venting. This leads to a smooth
operation even after long periods of standstill of the plant. Due to its innovative Teflon components, it works under high temperatures and is resistant to most kind of chemicals. PowerFlow is available in the nominal sizes of DN20/25/32 for every flat sealed fitting.

PF_Flange – N (steel disc), DN 40 – 200 (1 ½” – 8”) The Thermoclassic PowerFlow Flange-design valve with a double-steel-disc (N) (TCPFF- N) is a non-return valve for fluids, gasses
and steams. Its short design makes it easy to clamp it between pipe flanges according to DIN/EN, applicable with PN 6/10/16 as
per DIN EN 1092-1. Manufacturer: Reiche; Type: Thermoclassic (TC) PF_F- N.../ 40-50-65-80-100-125-150-200 (DN).
Other nominal widths or flange connections (e.g. ASME, BS, factory standards) can be ordered on request.
Consolidation of the flange body and the Reiche-patented PowerFlow-technology. Upgrading flow rate and energy consumption (less Power – more Flow). Optimal flow-increase for plant expansions at a constant nominal size. Replacement costs are reduced to a minimum, thanks to the standard installation length for non-return valves. For a maintenance-free installation between flanges, applicable at PN 6/10/16. Due to its broad sealing surface, no centering tools are necessary. The double-disc is made of austenitic steel, which works from -10°C (14°F) up to 300°C (572°F). A European Patent Application is pending – Made in Germany.
The internally guided valve plate grants a minimum of noise and ensures a leakfree use. At a constant pressure drop the PowerFlow enables, compared to the flange-version, a flow rate of the next higher
nominal valve size (e.g. DN 80 to DN 100). Do not hesitate to ask for an antistatic connection, another material or any other features.
