La v\u00e1lvula de compuerta de cuchilla de engranaje est\u00e1 disponible<\/p>\n

Create a dedicated Applications & Industries subsection detailing suitability for pulp & paper, wastewater, chemicals, and mining, including typical pressures, particle sizes, and service conditions; include short case snapshots and customer quotes.<\/p>\n

Caracter\u00edsticas:<\/b><\/p>\n

1. Cuerpo:<\/p>\n

a) El cuerpo integral con estructura de paso total garantiza un flujo suave, un montaje sencillo y una menor posibilidad de fugas en la carcasa.<\/p>\n

b) El dise\u00f1o del cuerpo sin ranuras elimina cualquier posible obstrucci\u00f3n cuando se cierra la v\u00e1lvula.<\/p>\n

2. Puerta:<\/p>\n

a) El borde biselado de la cuchilla proporciona una fuerte tensi\u00f3n de corte y un sellado herm\u00e9tico.<\/p>\n

b) El espesor de la compuerta se puede aumentar para hacer frente a una presi\u00f3n m\u00e1s alta.<\/p>\n

3. Asiento:<\/p>\n

a) El asiento de elast\u00f3mero en forma de U proporciona un sello perif\u00e9rico a lo largo del borde de la puerta y garantiza un sellado herm\u00e9tico en ambos<\/p>\n

direcciones de flujo.<\/p>\n

4. Otro:<\/p>\n

a) El cojinete de empuje doble minimiza el par requerido para la operaci\u00f3n.<\/p>\n
