Kontakt LLC has developed and launched into production a new product, the 1KO shutoff valve.
The 1KO shutoff valve is used as a device to automatically shut off the gas pressure regulator when the set output gas pressure is exceeded or decreased. It is installed upstream of the regulator and controlled by the output pressure downstream of the regulator.
The shutoff valve is designed for operation at an ambient temperature from -30 to +50 C and relative humidity of 30 to 98%.
The power source is compressed natural gas, purified from mechanical impurities and liquid droplets.
By agreement with the customer, the shutoff valve can be supplied as a complete unit either in a design for shutting off when the output pressure exceeds the permissible value or in a design for shutting off when the output pressure decreases below the permissible one.
Besides the shutoff valve of nominal diameter DN=50 mm, we are planning to develop and master the production of the 1KO shutoff valves with nominal diameters 80 and 100 mm.
It is possible to install a shutter position sensor to ensure the shutoff valve operation in the automated control system of the GDS.
On July 20, 2017, plant tests were conducted within the framework of interdepartmental tests by the commission with representatives of the plant and leading specialists of the relevant departments of Ukrtransgaz JSC.
At present, according to the results of the commission work, the product is being finalized, improved and prepared for testing at the facility.
