{"id":391,"count":7,"description":"Electric ball valves are valves for automatic shut-off or flow redirection. The UKSPAR catalog includes stainless steel coupling models Fig. K320-E for 24 or 220 V, flanged, welded and coupling versions PN16 or PN25, as well as a three-way L\/T-shaped valve. The K320-E model has a body and ball made of stainless steel EN 1.4301, threaded connection and PTFE seal. Other items are available on request, so materials, DN, drive voltage and price must be specified. Permissible parameters depend on the medium and seal properties, so they are checked in the complex.\r\n<h2>How to choose an electric drive for operating conditions<\/h2>\r\nThe electric actuator is selected not only by diameter. The main parameter is the torque required to rotate the ball at the maximum pressure drop. The actuator must have a sufficient margin, without exceeding the permissible load on the rod. Also take into account the voltage, operating time, cycle frequency, temperature and installation location. For a controlled process, the type of signal and the need for feedback are determined. The actuator and valve are selected as a single set. For wet rooms, open areas or special areas, the protection of the shell is checked. The usual version is not used where an explosion-proof actuator is required.\r\n<h2>Types of cranes by connection method<\/h2>\r\nThe coupling valve is mounted on a thread and is convenient for small DN pipelines. The category includes stainless steel models for 24 and 220 V and PN16 design. Brass is also used in threaded fittings, but the material of a specific valve must be checked with the card. The flange valve is connected with bolts and facilitates the dismantling of the fittings. The catalog includes PN16 and PN25 kits. The welded version forms a permanent connection and reduces the number of joints. The type of connection is selected according to the project, pipe material and service conditions. The three-way L\/T-shaped valve switches or distributes the flow. The hole pattern in the ball and operating positions are agreed upon before ordering.\r\n<h2>Functions and capabilities of the electric drive<\/h2>\r\nThe actuator transmits torque to the stem via a gearbox and rotates the ball 90\u00b0 between the \u00abopen\u00bb and \u00abclosed\u00bb positions. Two-position or proportional control is possible. For individual actuators, the catalog provides signals of 4\u201320 mA, 0\u201310 mA or 1\u20135 V, but the function must be confirmed during configuration. Automatic control sets the operating algorithm and provides control from the operator&#039;s station. Thermal protection, operating time and connection diagram are also checked.\r\n<h3>Manual override, limit switches, IP protection rating<\/h3>\r\nManual override allows the valve to be changed without power, if the actuator allows it. Limit switches stop the motor in the extreme positions and signal the valve status. They are set during installation. The IP degree characterizes the protection of the housing against dust and water. The catalog lists actuators with IP66 and IP67, but these values cannot be transferred to each kit. It is necessary to check the IP, temperature, cable entries and installation position.\r\n<h2>Integration into automation systems<\/h2>\r\nThe ball valve with electric drive can be connected to a control cabinet, controller or dispatching. Automation executes commands according to a schedule or sensor signal and transmits information about the position of the valve. Before integration, coordinate:\r\n<ul>\r\n \t<li>voltage;<\/li>\r\n \t<li>signal type;<\/li>\r\n \t<li>contacts;<\/li>\r\n \t<li>emergency situation;<\/li>\r\n \t<li>turn time.<\/li>\r\n<\/ul>\r\nConnection, adjustment and testing of interlocks are performed by a qualified specialist according to the manufacturer&#039;s diagram. Position signals are used to indicate and lock adjacent equipment. The logic is tested in normal mode and during power loss.\r\n<h2>Where to buy an electric ball valve<\/h2>\r\nYou can order a kit at UKSPAR with a selection of a valve, actuator and adapter. For calculation, please provide DN, PN, medium, temperature, connection method, voltage and control algorithm. Specialists will help you choose a coupling, welded or flanged version, check the torque and compatibility of materials. This simplifies the installation and operation of the remote control system.","link":"https:\/\/ukspar.ua\/en\/krani-kulovi-z-elektroprivodom\/","name":"Ball valves~ with an electric drive","slug":"krani-kulovi-z-elektroprivodom","taxonomy":"product_cat","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/ukspar.ua\/en\/wp-json\/wp\/v2\/product_cat\/391"}],"collection":[{"href":"https:\/\/ukspar.ua\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/ukspar.ua\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/ukspar.ua\/en\/wp-json\/wp\/v2\/product?product_cat=391"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
