Sistema HVAC Válvula de control motorizada eléctrica Control de flujo de agua
Las válvulas motorizadas de la serie HTW-V71 se utilizan para controlar el flujo de agua caliente y agua fría a través de la unidad fancoil en aplicaciones de calefacción, refrigeración o aire acondicionado, para controlar indirectamente la temperatura ambiente. Cuando el termostato envía la señal de control a la válvula motorizada, la válvula se abre con el agua fluyendo, y cuando la señal desaparece, la válvula, con la ayuda de su propio resorte, vuelve a su lugar original para cerrar la válvula para detener el flujo de agua

>>Installation Instruction
1.Dimensions Diagrams, Pleasse refer to fig 1
2.The valves can be mounted in horizontal or vertical piping, When installed in horizontal piping, the actuator must be above the valve body, and it can be titled left or right but it must NOT be below 85 degrees from vertical. Please refer to Fig 2.
3.If the valve as mounted in vertical piping, please be sure the cover of motor is waterproof.
4.When installing the actuator to a normally closed valve, the actuator must be placed in the manually open position by using the manual operating lever. The first time the valve operated electrically, the manual operating lever of the actuator will transfer to the automatic poison.
