One Piece (Unibody) Ball Valves
One Piece Ball Valves (also known as Unibody Ball Valves) feature a solid, single-piece cast or forged body construction with no joint seams in the valve body shell. Because the body has no structural joints, potential external leak paths to atmosphere are virtually eliminated, making One Piece Ball Valves exceptionally safe and leak-proof for hazardous fluid transport.
Zeron Fasteners manufactures compact One Piece Ball Valves with reduced bore (standard port) flow channels. Widely preferred in commercial plumbing, HVAC circuits, oil dispensing units, and process utilities where budget economy, high mechanical integrity, and minimal space envelopes are paramount. Fabricated in Stainless Steel 316 and Carbon Steel with pressure ratings up to 1000 WOG and Class 150#.
