Válvulas motorizadas de 3 vías con retorno por resorte Válvula de bola de agua Válvula de bola de material de latón
Las válvulas de bola motorizadas de la serie HTW-71 se ensamblan con una fuerza de actuador de 8 Nm, 16 Nm, 20 Nm a 24 Nm con un cuerpo de válvula de tamaño G1 (DN25) a G2 (DN50). Con fuente de alimentación opcional: AC24±10%, 50/60Hz o AC220±10%, 50/60Hz, cuya señal de control se puede personalizar como ON/OFF, 0(2)~10VDC o 4~20mA, con o sin no contacto de realimentación de tensión. Son ampliamente utilizados en sistemas de calefacción, aire acondicionado, refrigeración y autocontrol de edificios. Con su ajuste preciso del caudal medio, las válvulas de bola de esta serie controlan la temperatura, la humedad y la presión con el fin de ahorrar energía.
>> General
HTW-71 Series Motorized Ball Valves are assembled with a force of actuator from 8Nm,16Nm,20Nm, to 24Nm with valve body sized from G1(DN25) to G2(DN50). With power supply optional:AC24±10%, 50/60Hz or AC220±10%, 50/60Hz, whose control signal can be customized as ON/OFF, 0(2)~10VDC or 4~20mA, with or without non-voltage feedback contact.
They are widely used in Heating, Air-Conditioning, Refrigeration, and Building Auto-Control system. With their precisely adjusting of the medium flow rate, this series ball valves accordingly control temperature, humidity, pressure for an Energy-Saving purpose.
