        RTKI10, RTKIR10 — steel shut-off needle valves.

        Designed for installation in systems, monitoring and metering devices, various auxiliary piping systems, industrial installations and equipment, pressure measurement lines and other parameters of the working environment

        RTKI10 is a shut—off needle valve.
        RTKI10 is a shut—off needle valve.

        The safety of operation of pipeline systems depends on the quality of shut-off valves. Our catalog contains only reliable products with a high class of tightness.

        Purpose of needle valves

        Needle valves are used in pipeline systems in which liquid and gaseous media move. The use of products can be carried out without restrictions, including in the food industry and in industries where chemically aggressive media are transmitted through pipes.

        The most common locking mechanisms of needle design are installed in the following systems:

        • Auxiliary pipelines.
        • Industrial installations.
        • Monitoring and accounting devices.
        • Devices for measuring pressure and other important physical parameters.

        When selecting a new needle valve, the diameter of the pipeline on which this product is installed should also be taken into account.

        Advantages of needle valves RTKI10 and RTKIR10

        Needle valves RTKI10 and RTKIR10 have the following positive characteristics:

        • The use of a conical spool with a small angular deviation allows the liquid or gaseous medium to be fed smoothly. Thanks to this feature, it is possible to significantly increase the safety of operation of pipeline systems, including avoiding hydraulic shocks.
        • The housing is made of durable materials, so the locking device will last much longer. This quality is also very important in case of possible mechanical influences on the product, as well as at high pressure of the internal environment.
        • The significant service life of the product is due to the low coefficient of friction between the mating parts. In needle valves, this technical solution is represented by the work of the steel-bronze running pair.
        • RTKI10 and RTKIR10 valves have a wide variety of connection sizes, therefore they can be installed on most types of equipment of domestic and foreign production.
        • The presence of an unloading device at the RTKIR10 valve also makes it possible to extend the service life of the product. This design feature allows you to relieve pressure on the line after disconnecting the main valve.

        The RTKI10 and RTKIR10 valves can be manufactured with a different combination of thread size at the inlet and outlet of the device, which also contributes to a more versatile use of the product.
