3/4″ Locking Ball Valve 1000WOG Full Port LOTO Safety Shut Off Valve
3/4″ locking ball valve, 2pc threaded full port design, brass/304/316 body, built lock for LOTO compliance, ideal for food, gas & industrial pipeline isolation.
Description
I. Basic Product Function
The 3/4″ locking ball valve is a two‑way shutoff valve featuring an integrated locking handle mechanism. Its primary function is to enable rapid opening or closure of pipeline media, while a dedicated locking slot secures the handle in the fully open or fully closed position. This design meets global LOTO (Lockout/Tagout) safety requirements, preventing unintended actuation caused by human error or equipment vibration. As a 2‑piece threaded locking ball valve, it offers straightforward disassembly and maintenance. Combined with a full‑port flow path, it ensures minimal pressure drop and is compatible with media such as water, natural gas, food‑grade cleaning fluids, and light oils.

III. Material Selection Guidance
For general water supply and HVAC lines, the brass version is recommended. For oil/gas and mild acid media, the stainless steel locking ball valve is preferred. For high‑pressure hydraulic or gas branch services, the 1000W pressure‑rated model is the direct choice. The integrated locking handle requires no additional accessories; standard padlocks can be inserted directly into the locking slot, fully complying with OSHA industrial safety standards.
IV. Industry Applications and Real‑World Case
This valve is widely employed in food processing, oil/gas extraction, commercial HVAC, municipal water supply, and small‑bore chemical lines.
Real‑world application case: GEA Food Processing Demonstration Plant (Stuttgart, Germany). In the plant’s CIP (Clean‑in‑Place) circulating cleaning lines, the 3/4″ locking ball valve was adopted in large quantities. The CIP lines require sectional isolation during maintenance; after closing the valve, operators secure the lockable handle ball valve with a padlock through the locking ear, effectively preventing accidental reopening that could cause cross‑contamination of cleaning fluids. The full‑port locking ball valve ensures no flow restriction, leaving no residue in the cleaning media path. Its stainless steel body withstands high‑temperature acidic/alkaline cleaning agents, ensuring long‑term stable operation and meeting EU food equipment safety regulations.
Beyond this case, the locking ball valve is also extensively used in oil/gas gathering branch lines, commercial chilled‑water circulation systems, and small hydraulic units, delivering both efficient shutoff and enhanced operational safety.
