Doğrudan-etkili 2/2-yollu standart solenoid kontrol vanası
Tip 2871 / ID No. 255629
Ürün tanımı
Doğrudan-etkili solenoid kontrol vana olan Tip 2871 kontrol döngülerinde ayar ünitesi olarak kulanılır. Bir elaskomerik yuva sızdırmazlık elemanı sayesinde vana DN özel nominal basıncına kadar sızdırmaz biçimde kapanır (entegre kapanma fonksiyonu). Vananın pistonu; olağanüstü ayar karakteristiklerine yol açacak şekilde sürtünmesiz olarak birleştirilmiştir. Bu vana özellikle kontrol görevleri (yüksek kontrol aralığı, kuru gazlar, vs.) için uygundur.
