HYDROCONTROL DN15 KVS388 M THREADED END
Oventrop double regulating and commissioning valves are installed in the pipework of hot water central heating and cooling systems and serve to achieve a hydronic balance between the various circuits of the system.The balance is achieved by a presetting with memory position.
The required values of presetting can be obtained from the flow charts. All intermediate values are infinitely adjustable.
The selected presetting can be read off two scales (basic scale and fine adjustment scale, see illustration presetting). The Oventrop double regulating and commissioning valves have 2 threaded ports for fill and drain ball valves or pressure test points for the measurement of differential pressure.
The double regulating and commissioning valves may be installed in either the supply or the return pipe.
When installing the valve it must be ensured that the direction of flow conforms to the direction of the arrow on the valve body and that the valve is installed with a minimum of L = 3 x Ø of straight pipe at the valve inlet and of L = 2 x Ø of straight pipe at the valve outlet.
The flow charts are valid for both, installation in the supply or the return pipe, provided the direction of flow conforms to the arrow embossed on the valve body.
In cooling systems using mixtures of water and glycol, the correction factors related to the indicated chart values have to betaken into consideration.
