Wafer Type Ball Valves

Wafer Type Ball Valves (often termed Sandwich Ball Valves or Short Face-to-Face Ball Valves) are ultra-compact quarter-turn valves designed specifically for installation between adjacent pipe flanges where pipeline space and weight are severely restricted. By eliminating long flange necks, wafer ball valves achieve a minimal face-to-face dimension up to 70% shorter than conventional flanged valves.

Zeron Fastners manufactures Wafer Type Ball Valves in single-piece and two-piece bolted constructions, engineered to clamp securely between ANSI 150# or 300# flanges using through-bolts. Widely utilized in modular skid systems, tank farm drains, mobile tankers, and petrochemical facilities, these valves provide full-port or regular-port flow with exceptionally low torque and tight shutoff.
