max. pressure: 10 bar / 145 psi max. temp. 130°C / 266 °F

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.

Lowest operating temperature: -10 °C / 24°F (DN 100 ) -30°C / 22 °F ( DN 150- 200 )

Top operating temperature: 130°C / 266 °F

Operating pressure: 10 bar / 145 psi

Purpose

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.

Main features

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).

Installation instructions

The TCF-N non-return valve can be installed by clamping between pipe flanges as per DIN EN 1092-1, applicable with PN 6/10.

Because of the broad sealing surface on the outlet side, neither an intermediate ring nor a spiral centering is necessary.

Through perfectly-matched proportions between spring pressure and disc diameter, the opening pressure is consistently 0.02 bar

(0.290 psi). Other flow directions will change these values only up to 0.01 bar (0.145 psi). When other media is used, the

equivalent water flow volume has to be calculated.

Main features


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.

TC_RV K (Polyamide disc), DN 25 - 32 (1“– 1 ¼“) Thermoclassic gravity circulation check valve for pipes (RV) with a plastic valve “saddle”-disc (K) (TC RV- K). An insert-valve

with to screw on the pump by means of a union nut. Also available with screw threads on each side to fit into a pipe system.

The innovative "saddle"-disc design provides a 100% flow rate as well as a minimum of pressure drop while operating. The

plastic “saddle”-disc works to maximum of 130°C/266°F, PN 6/10.



Operating pressure: 6 bar / 87 psi / Not to be taken into account in closed systems

Purpose

For silent operating in heating-, hot water- and solar installations. Also available as a pipe connection, with screw threads on each side. For preventing unintended thermal upthrust. To separate different heating circuits. To prevent reverse circulation. Also available with a lifting device /A.



Main features

Because of the specially designed “saddle”-disc, the flow is 100%.

The innovative design also provides automatic deaeration.

As a result of the maximum flow, pressure losses are much lower than in conventional check valves.

This reduces heat loss and thus provides energy savings. It can also extend the lifetime of the pump.

The lifting device /A simplifies filling and draining of the plant.

Due to its thread, the lifting device can also be “tightened”. In this way leakages are eliminated.

On request the TC RV-K is also available with a connection for the suction side of the pump.

Disc: Teflon, temperature 190°C (374°F), PN 6/10, valve dimension: 1.5mm (0.06 inch) high, nominal sizes: DN20, DN25, DN32.

Lowest operating temperature: -10 °C / 14°F



Purpose

Applicable at any plant location. For silent operating in heating-, hot water and solar installations. For preventing unintended thermal upthrust. To separate different heating circuits. To prevent reverse circulation.

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.

The PowerFlow can be installed in two ways to fit at any position of the plant:

(1) to insert between flat sealing fittings or

(2) for direct insertion in the pressure connection of the circulation pump.

At positions in solar systems where problems through air cannot cause malfunction of the valve

(e.g. when installed in horizontal pipes or overhead in return pipes), we recommend the use of

the Power Flow without the airlock (PF- T instead of PF- TL).

With excellent hydrodynamic properties and drag coefficients, applicable at PN 6/10/16


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.




Purpose

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.



Main features

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.

The TCPFF-N double-disk non-return valve can be installed by clamping it between two pipe flanges as per DIN EN 1092-1.

Applicable at PN 6/10/16. Because of the broad sealing surface on the outlet side, neither an intermediate ring nor a spiral

centering is necessary to ensure a leakfree flange connection.
