Abstract
LA VALVULA TIENE UN PISTON SITUADO EN UNA CARCASA DE VALVULA PARA CONTROL DEL FLUJO MEDIO DE PRESION PRICIPAL A TRAVES DE LA VALVULA CON LA AYUDA DE UN FLUJO PILOTO QUE DERIVA DEL FLUJO DE PRESION MEDIA PRINCIPAL Y QUE SE CONTROLA POR MEDIO DE UNA VALVULA PILOTO. PARA CONSEGUIR EL CONTROL INDEPENDIENTE DE LA TEMPERATURA SIN AUMENTO DEL AREA DE LAS CAMARAS DE FLUJO PILOTO SE DISPONE DE UNA RESTRICCION (17) EN LA DIRECCION DEL FLUJO PILOTO Y UNA RESTRCCION ADICIONAL ENTRE EL PISTON DE VALVULA (2) Y LA PARED CILINDRICA (15) QUE RODEA AL PISTON DE VALVULA DE LA CARCASA DE LA MISMA, DICHA RESTRICCION QUE TIENE LA FORMA DE UN CLARO PERIFERICO (11) DE MAYOR LONGITUD AXIAL QUE ANCHO.
