SLV
Flanged 2-Way Ball Valve
The SLV Flanged 2-Way Ball Valve is a quarter-turn shut-off valve that bolts directly between pipe flanges. A simple turn of the handle rotates the ball to give bubble-tight isolation, making it a dependable workhorse for starting and stopping flow across a wide range of process and utility services.
Product Benefits
- Tight shutoff: A floating-ball design presses the ball against the downstream seat under line pressure, so isolation stays tight without complex trim.
- Quarter-turn action: The valve opens and closes quickly with low operating effort.
- Investment-cast body: The cast construction gives a clean, consistent pressure envelope.
- Safety built in: Anti-static and fire-safe construction is part of the design rather than something added on.
- Ready for automation: The standardized top flange lets a gear operator or actuator be fitted later without changing the valve itself, which makes it a sound choice where a plain commodity valve might fall short.
Where It's Used
- General-purpose isolation: The valve serves industrial process and utility pipelines: water, air, steam-adjacent utilities, oils and many chemical services, depending on the materials selected.
- Easy to install: Flanged ends make it simple to fit and swap in plant piping that follows common international flange standards.
- Block valve duty: Typical uses include block valves around pumps and equipment, and battery-limit isolation.
- Simple on/off service: It suits anywhere a full quarter-turn shut-off is preferred over a multi-turn valve.
Good to Know
- Material choices: The body and ball are offered in stainless steel grades for corrosive media or in carbon steel for general service.
- Soft PTFE seats: Seats from the PTFE family seal softly and resist a broad range of chemicals.
- Main selection step: Matching the body and seat materials to the medium and temperature is the decision that matters most.
- Predictable dimensions: Because the design follows widely used international valve and flange standards, face-to-face dimensions and drilling are predictable, which simplifies replacement of existing valves.
- Room to automate later: The ISO-standard mounting pad keeps the door open for future automation.
