Technical information about self-closing taps, flush valves and mixer:

 

MCM’s automatic closing taps are opened by a device, activated by pressing a button, lever, pedal, which causes it the closing after a certain period of time.

MCM’s self-closing taps have a closing time regulation cartridge realized in special materials with innovative technical features that allow a safe and good functioning during the time at a low-cost.

MCM’s self-closing taps are tested for up to 1.000.000 work cycles and are designed to minimize water hammering.

Minimum operating pressure: 0.1 bar.

Recommended maximum working pressure: 5 bar.

MCM’s self-closing taps and mixers have the following possible adjustments:

•Closing time regulation:

-with standard cartridge (closing time pre-set by MCM during production),
-with adjustable cartridge (closing time adjustable by the customer);

•Flow regulation (optional);

•Temperature regulation (mixers only).

Closing time pre-set by MCM (standard cartridge) – A/B/C/D/E –

 

With the standard cartridges, the closing time is pre-set by MCM during the production phase on the basis of customer requests that can choose between the following closing times from 3 to 25 seconds (*):

A approx 3 ± 1 sec.
B approx 4/6 ± 1 sec.
C approx 8/12 ± 1 sec.
D approx 12/16 ± 2 sec.
E approx 15/25 ± 3 sec.

Closing time adjustable by the customer (adjustable cartridges) – F –

 

With the standard cartridges, the closing time is pre-set by MCM during the production phase on the basis of customer requests that can choose between the following closing times from 3 to 25 seconds (*):

F approx 0/40 ±10 sec.

With the adjustable cartridge it is possible to choose the closing time simply and quickly without having to disassemble the tap. In the button there is a screw: turning the supplied Allen wrench clockwise you can decrease the time while turning it anticlockwise you can increase the time.

(*): The times shown are indicative as they may vary over time depending on the quality of water and how it is used.

FLOW REGULATION

 

On request, MCM’s self-closing taps and mixers can be supplied equipped with flow regulation devices (water flow):

– with flow limiter of 6 L/min;
– with adjustable flow regulator.

[L/min](±10%) A [L/min](±10%) A [L/min](±10%) A [L/min](±10%) A
Pressure 1 2 3 4
0.5 12.0 10.6 7.8 2.3
1.0 16.8 14.4 10.2 2.8
1.5 21.5 19.8 13.2 3.4
2.0 24.0 22.3 16.8 3.9
3.0 33.0 29.4 21.6 5

The flow regulator can be pre-set directly by MCM during the production phase depending on customer requests or by the customer himself by the following procedure:

1• using a wrench 24, unscrew the cartridge from the tap body;

2• extract the cartridge and turn the cup (G) on the grid (H) choosing the necessary water flow that can vary from position 1 (fully open: maximum flow) to position 4 (all closed: minimum flow);

3• reposition the cartridge in the body of the tap applying a tightening torque of 12 Nm.

*: the flow rates shown are indicative as they may vary over time depending on the quality of water and how it is used.

 Energy saving, no water waste

The use of self-closing taps, flush valves and mixers reduces significantly the water waste.
