Special features
- Consisting of piggable T-piece with integrated ball valve and actuator
- Cavity-free Piggable Metering Valve
- Inside diameter of pipe, according to DIN 2430
- Seat rings, spring-loaded on one side
- Floating ball, i.e. sealed by both seat rings
- Corrosion-resistant materials to withstand corrosive process media
- DIN ISO 5211 interface as standard
- PTFE V-ring packing loaded by disk springs
- TA-Luft
- Blow-out-proof shaft
- Anti-static version with conductive shaft bearing
- Leakage requirements according to DIN EN 12266 or API 598
- » General information about pigging systems
- For pipes and valves acc. to DIN2430
- High cleaning performance without any additional rinsing process
- Long service life (depending on media)
- Resistant to chemicals even with corrosive media
- Two distinctive sealing lips and a formed middle part enable it to run without any problems in bends
- Bi-directional operation mode, i.e. the pig is symmetric, therefore can be used in both directions
- A magnet in core of the pig allows use in automated systems
- Pigs maintain a constant and even run inside bends and valves
- Sealing lip diameter approx. 4 % larger than the pipe diameter for a much higher scrape performance
