Special features
- Discontinuous sampling valve
- Consisting of ball valve and hand lever or actuator
- Inline sampling ball valve for horizontal installation
- Tight-closing, cavity-free sampling valve designed to sample liquids from flowing media without a bypass
- Body of stainless steel (1.4571)
- Ball / shaft of stainless steel (1.4571)
- Representative sampling due to the direct installation in the pipeline
- DIN ISO 5211 interface as standard
- PTFE V-ring packing loaded by disk springs
- No necking or abrasion of the pipeline during sampling
- Venting or control connection 1/8"
- Sear ring shells for a sampling without cavity
- The sampling valve has a connection as per ISO 4796, DIN thread GL 45
- Leakage requirements according to DIN EN 12266 or API 598
- Sampling with a defined sample volume from a material flow
- Diverse sample volumes
- In the case of liquid media, depressurised sampling and therefore sampling at high pressures and from vacuum permissible
- No fore- and no after-running
- No risk of overflow as the sample volume is determined per stroke
- No direct connection to the environment
- No false operation due to long opening times
Accessories
- Hand lever
- Actuator
- Protective box in stainless steel
- Special gas chamber exhaust
- Pneumatic switch box for automation
- Pneumatic timer
- Counter
- Adapter for locally employed sample containers
Options
- Automatic with 180° rotary actuator
- Hand lever (180°)
