Abstract

La presente invención se refiere a un miembro de válvula que incluye un cuerpo, un forro de compuerta que tiene un canal para recibir un material que fluye por dispensarse y un vástago de válvula con extremos próximo y distal; el forro teniendo una abertura que forma un asiento en comunicación con el canal y el cuerpo sosteniendo el vástago que incorpora una cavidad que se extiende a lo largo de su longitud a un punto en proximidad cercana a su extremo distal y que está adaptada para acomodar un material de intercambio de calor, el miembro incorporando adicionalmente un cilindro y un pistón movible colocados en él, el pistón estando colocado al vástago de válvula y teniendo lados opuestos contra los cuales actúa el material de intercambio de calor para reciprocar el pistón y donde el vástago de válvula incluye al menos un pasaje adaptado para intersectar la cavidad y conectar con el cilindro en al menos un lado de y en al menos una posición del pistón.
