Shut Off Valves

Shut-off Valve (2, 3 or Push-Lever)

Features:
- Fabricated construction
- In the initial stage of opening and final stage of closing, the disc moves parallel to the body seat providing a friction-free motion
- Various seat arrangements
- A special lever mechanism connects to, and applies pressure on the centre of the disc
- The shaft is arranged close to the valve centreline
- Operating lever and guide levers are of nearly the same length
- Compact design
- Materials according to operating conditions
- Valve actuation in accordance with customer’s requirements (man./electr./hydr./pneum.)
- Pressure rating up to PN 10
- Operating temperatures up to 600 °C (1100 °F)
- Nominal diameters up to 4000 mm (160 inch)
- Other sizes or operating conditions on request

This design guarantees
- Low wear at the seats due to parallel and friction-free closing and opening of the valve disc
- No jamming of lever system not even at higher temperatures, due to nearly the same length of drive lever and guide levers
- Seat tightness by central disc connection/pressure point providing self-aligning feature
- Low torque requirement at the drive shaft due to close proximity to the valve centreline

Operating conditions
- High operating pressure in open as well as in closed position
- High frequency of operation
- Temperature differences
- Temperature fluctuations
- Shut-off of clean and dust laden air and gas media
- Short closing and opening time

Service applications
- For all clean and dust laden air and gas media
