Valve head complete with flywheels and gaskets are used for replacement, in the event of a malfunction, as a repair kit. The valve head is a unit of water-folding fittings (mixer) for cold and hot water with a nominal pressure of up to PN 1.0 MPa (10 kgf / cm2) and a temperature of up to + 175 ° C, which is installed in buildings for various purposes. Material of the main parts: brass LS 59-1. Pipeline connection thread, D – M 18×1.The principle of operation of the I / O is very simple: the valve-box with a rubber cuff is equipped with a stem, which, during a screw gear, extends, tightly closing the valve seat with a rubber gasket. The uncomplicated design and interchangeable parts make the repair of the screw head and the replacement of the rubber gasket much easier than that of the ceramic analogue. Complete set: 2 pcs of high-pressure, 2 pcs of 4-sided “Tulip” type flywheels made of high pressure PE, 2 pcs of gaskets.
