butterfly valve / pneumatic / shut-off / for gas

Being part of the proven K?HME 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 flap 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 single seat
design with EC-type-Examination (Module B) in acc. with PED (up to DN 1600)
- Main shut-off for gas systems
- Pipe systems for gaseous media and fuels in all industrial sectors

Nominal size: DN 300 to 3000
Operating pressure: max. 2.5 bar g up to DN 700 (static)
from DN 800 to DN 1600: 1.0 bar g (static)
from DN 800 to DN 1600: 1.0 bar g (static)
Differential pressure switchable: up to 2.5 bar (depending on the nominal size
and actuator size)
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
- Heavy duty design for high amount of operating cycles
- High-performance valve with long service life
