 A105-ENP Valve Ball for Ball Valve

Electroless nickel plating is an alloy of nickel and phosphorous. Electroless Nickel Plating(ENP) Ball has been widely applied in valve ball production with its advantages such as simple processing, low-cost, uniform thickeness and large-area plating. Many clients will specify A105/ENP trim ball valve because they believe it to be a more cost effective option than a full stainless steel ball.
