Caratteristiche strutturali: La coppia di tenuta \u00e8 ben abbinata e altamente efficiente. Le superfici di tenuta dell'otturatore e della sede della valvola sono realizzate mediante la sovrapposizione di leghe dure a base di cobalto con rivestimento Samte di diversa durezza. La tenuta \u00e8 affidabile, con elevata durezza, resistenza all'usura, resistenza alle alte temperature e resistenza alla corrosione. Lo stelo della valvola \u00e8 sottoposto a trattamento di tempra e nitrurazione superficiale, che si traduce in un'eccellente resistenza alla corrosione, prestazioni antiabrasione e resistenza all'usura.![\"\"](\"https:\/\/cnkazev.com\/wp-content\/uploads\/2026\/04\/DATA-FORM-2.webp\")
