SLV
Pneumatic 3-Piece Ball Valve
The SLV Pneumatic 3-Piece Ball Valve puts a rack-and-pinion pneumatic actuator on a serviceable three-piece ball valve, with threaded or welded ends to suit the piping. It delivers fast, automated on/off control while keeping seat and seal replacement an in-line job.
Product Benefits
- Painless seat service: Automated valves eventually need seat work, and the three-piece body makes it simple: unbolt the body, swing out the centre, renew the soft parts and rebuild, leaving the end connections and the actuator in place.
- Short maintenance windows: Over years of cycling, that translates into brief shutdowns and low spares cost.
- Two actuator types: Double-acting and spring-return actuators cover both routine automation and fail-safe duties.
- Standard accessory fit: NAMUR-standard air connections and internationally standardized mounting let common accessories bolt on directly.
- Solid pressure rating: The rating gives margin across typical process and utility services.
Where It's Used
- Automated isolation: It handles isolation on process skids, OEM machinery, utility stations and general industrial pipelines.
- Frequent remote operation: It fits anywhere regular, remotely commanded on/off duty is wanted in small to mid-size bores.
- Threaded or welded systems: The wide choice of end connections lets one valve series serve threaded utility piping and welded process systems alike.
- Fail-safe or everyday: Spring-return builds take on fail-safe shut-off duties, while double-acting builds cover everyday sequenced operation.
Good to Know
- Check the end standard: End options span several thread forms as well as butt-weld and socket-weld preparations, so confirm the site's piping standard when ordering.
- Materials to suit: Body and ball materials include stainless steel grades, carbon steel and duplex, with PTFE-family and elastomer seals matched to the medium.
- Special travel options: Beyond the standard quarter turn, adjustable and multi-position travel options exist for special switching schemes.
- Fix the fail position: Specify the desired failure position up front.
- Clean, dry air: Keeping the air supply clean and dry is the other habit that keeps pneumatic packages reliable.
