A105+ENP Ball Valve
A105+ENP Ball Valves, A105 Ball with Electroless Nickel Plating, thickness of an .003” (76 micron) and A Vickers hardness of 600 minimum.
air release valve for water line
Key Specifications / Features
There are two types of request for A105+ENP Ball Valve:
1. A105 body ball valve, with ENP coating on A105 body (internal) for corrosion resistance.
2. The valve ball is A105+ENP coating.
A105+ENP Ball Valve refers ball valve with the valve ball plated with Electroless nickel.
The thickness of an .003” (76 micron) EN plated if requested ball resists scratches.
A Vickers hardness of 600 minimum as standard (further hardening can be performed up to 900vh) for ENP ball.

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.
