The pig-iron latch 30ch6br with a diameter of 80 mm represents an element of pipeline fittings which is intended for installation as the locking device. In most cases by means of latches to be made transportation of such working environments as steam, oil, gas and water. Use of latches of this kind for transportation of other gaseous or liquid environments is also possible. The main condition which should be observed at the organization of a global network of the pipeline with use of such element as the latch 30ch6br dimension of 80 mm, is observance of service conditions. That is the working environment in relation to material of which latches pig-iron are made has to be nonaggressive.
The modern latch pig-iron 30ch6br manual control with a diameter of 80 mm is in most cases used in systems of the pipeline of heating and water supply for opening or full overlapping of a stream of a working environment. It should be noted that at this type of latches only two provisions of work - it is closed and it is opened. On manufacturing techniques the case, a locking element, a spindle, a cover and a guide, such detail as a latch 30ch6br Du 80 are made of high-quality cast iron. Type of accession of such latches - flange. To provide the normal efficient environment for a detail, nominal pressure in the pipeline should not exceed 1,0 MPas. The climatic modification of a detail conforms to all requirements specified in state standard specification 15150-69. The mass of a detail makes 18 kg. As for a class of tightness, a latch pig-iron with a diameter of 50 mm, she answers all standards of state standard specification 9544-93. Working temperature of the product transported by means of a latch should not exceed +225 °C and there should not be below -40 °C.
