Smoother water delivery, more comfortable water use

Extra high flow PPR piping system

I don't know if you have noticed cases of water meter idling online?

In life, some homeowners will find that the water bill at home is abnormally high, and then realize that the water meter at home will also idle and count when not using water. The reason for this phenomenon is that the pressure of the water supply network is very unstable, the water in the water meter due to pressure changes in the reciprocating flow, although relatively slight, but the water meter is more sophisticated, it will also be monitored and counted.

How to solve this abnormal phenomenon, in fact, is very simple, is in front of the water meter to install a check valve.

So what is a check valve, and what role do check valves play?

What role does the check valve play?

Koate PP-R check valve belongs to the automatic valve class, mainly used for one-way flow of media on the pipeline, only allows the medium to a direction of flow, opening and closing parts rely on the flow of media and the internal spring two forces to open or close by themselves, to prevent backflow of media in the pipeline.

Koate PP-R check valve

Unidirectional passage to prevent backflow
Mainly used for one-way flow of water on the pipeline.
It only allows water to flow in one direction.
In order to prevent water backflow, resulting in the system can not be used normally.

Koate PP-R check valve working principle: water flow from the inlet end, from the outlet end out. The water flows in from the inlet end and out from the outlet end. When the inlet pressure is greater than the spring resistance of the non-return valve spool, the valve is opened. On the contrary, the valve is closed when the water flows backward.

Koate PP-R Check Valve

Proper spring lifting design
Let the water meter empty become the past
When flowing downstream, the normal flow is maintained, and
When the flow is reversed, the flow can be terminated.

When installing the check valve, the arrow direction marked on the valve body should be consistent with the direction of water flow.

Installation of check valve in front of the water meter can prevent pressure fluctuation caused by pipe surge and can greatly reduce the phenomenon of water meter rotation.

Precision copper core Safety and reliability

The outer shell of Koate PP-R check valve is made of Nordic Chemical Industry PP-R material.
PP-R raw materials, the inner core is made of CW617N European standard environmental protection copper.
Safe and environmental protection, reliable connection

Koate PP-R check valve

All the way to refine more than
Health and safety in both directions

I: No need to wait for hot water

In the hot water circulation system
Check valve can prevent the tap water directly into the hot water return pipe
This prevents the normal use of hot water

Two: refuse to drink toilet water

Toilet water inlet installation check valve
Can prevent the water in the toilet tank back into the pipeline
Pollution of living water, affecting health

koate PP-R check valve working principle: water flow from the inlet end, from the outlet end out. When the inlet pressure is greater than the spring resistance of the non-return valve core, the valve is opened. On the contrary, the valve is closed when the water flows backward.

Small details, big future.
