butterfly valve / pneumatic / regulating / for gas

Being part of the proven KÜHME high-performance valve series for industrial applications, the PKIII type is used in any application where safe and quick shut-off of gaseous media is required. The electro-pneumatically controlled quick-closing butterfly flap valve sets standards for tightness, service life and reliability even in the most demanding applications. The butterfly flpa valve is mainly used as a tight shut-off device for gaseous media in systems with low pressures.

Media: gaseous
Application: Power plant technology, Steelworks, Biogas & Landfill gas,
Industrial combustion, Air separation plants PSA

Application areas
- Automatic shut-off valves for gaseous fuels, designed as steering arm flap in double
seat design with EC-type-Examination (Module B) in acc. with PED (until DN 1300)
- Main shut-off for gas systems
- Pipe systems for gaseous media in all industrial sectors

Nominal size: DN 300 to 3000
Operating pressure: max. 2.5 bar g,
from DN 800 upwards: 1.0 bar g (static)
Differential pressure for operation: up to 200 mbar
Operating temperature: max. + 300°C

Advantages
- Closing time < 3 seconds
- Safety guaranteed by the proven sealing system with soft seal (leakage rate A in acc. with EN 12266-1)
- Closing of the valve is dampened to reduce pressure surges in the pipeline
- Double seat - one valve instead of two separate valves - compact and cost-efficient
solution

- Convenient automatic testing of the sealing system during plant operation - without
having to dismantle the valve
- Heavy duty design for high amount of operating cycles
- High-performance valve with a long service life
