Product Description

Manual regulation valve for controlling the fluid in the emitters of eating systems. These special valves can be converted from manual to thermostatic operation by simple replacement of the adjusting knob with a thermostatic control head. This means that the ambient temperature of any room in which they are installed can be constantly maintained at the set value. These valves have a special tailpiece with rubber hydraulic seal, permitting quick, safe onnection to the radiator without the use of additional sealing materials.

Specifications:

Case: Brass CW617N-UNI EN 12165

Stock: Brass CW614N-UNI EN 12164

Branch pipe: Brass CW614N-UNI EN 12164

Gaskets: EPDM peroxide

Application: Heating system

Maximum working pressure: 10 bar

Working principle:

Manual regulation valve rotates the handwheel to rotate the valve core, which plays the role of opening and closing.

The clockwise direction is off and the counterclockwise direction is on.

Installation:

Manual regulation valve must be installed in horizontal position

Warnings: Manual regulation valve is installed incorrectly,two faults:

1) The presence of vibrations similar to hammer blows is caused by the fact that the

fluid passes through the valve in the direction opposite to that indicated by the arrow on the

body. To eliminate this malfunction, it is enough to restore the correct flow direction.

2) When the valve is opened / closed, the existence of noise is due to the high system

pressure difference. In order to solve this problem, it is recommended to install a variable

frequency water pump, a differential pressure regulator or a differential pressure bypass

valve at the same time.
