SLV
Pneumatic Flanged 2-Way Ball Valve
The SLV Pneumatic Flanged 2-Way Ball Valve mounts a compact rack-and-pinion pneumatic actuator on a flanged ball valve, using plant air to swing the ball open or shut in moments. It is the standard answer where automated isolation has to be fast, frequent and dependable.
Product Benefits
- Fast, high-cycle duty: Pneumatic actuators stroke quickly and tolerate high cycling, making this valve well suited to lines that open and close many times a day.
- Two actuator families: Double-acting units cover general automation, while spring-return units drive the valve to a safe position if air is lost.
- NAMUR air connections: The air connections follow the NAMUR convention and the mounting dimensions follow international standards.
- Accessories bolt on: Solenoid valves, limit switches and positioners from mainstream instrument makers fit directly, which keeps spares simple and avoids being locked into one accessory brand.
Where It's Used
- Automated on/off duty: The valve serves process and utility pipelines across general industry, feeding equipment and sequencing batch operations.
- Remote or interlocked isolation: It also provides isolation commanded from the control system or from an interlock.
- Broad size range: Sizes span small process lines up to large distribution headers.
- Fail-safe pick: Spring-return versions are the usual choice for duties such as emergency shut-off on a supply line.
- Routine automation: Double-acting versions handle everyday open and close automation.
Good to Know
- Material options: Body and ball materials include stainless steel grades, carbon steel and duplex stainless, with PTFE-family and elastomer seals to suit the medium.
- Configurable rotation: Rotation can be set beyond the standard quarter turn, including multi-position travel options for special switching arrangements.
- Define the fail position: Specify whether the valve should fail open, fail closed or stay put on air loss, as this determines the actuator type.
- Clean, dry air: A clean, dry air supply and a correctly sized actuator are the two practical points that keep a pneumatic package trouble-free for years.
