Product category: Components, ancillary equipments

Goggle Valves

Valve approved to „Man-safe“ standards (goggle valve - openwork structure)
The design provides 100% shut-off of media flow
Total separation of the gas main in the closed position, thus ensuring no passage of the media from the upstream to the downstream gas main, i.e. „Man-Safe“ isolation
Uniformly arranged clamping/unclamping hydraulic rams on one side of the valve body
Valve body with one movable and one fixed body sealing seat
Goggle plate seating/clamping is of mechanical pressure effected by the spring package within the hydraulic rams. Opening/ unclamping is effected by hydraulic pressure onto the rams
Dual circuit hydraulic systems available
Open structure or totally enclosed design
Venting to atmosphere of totally enclosed type in closed position
Valve actuation in accordance with customer’s requirements (electr./hydr./pneum./man.)
Very low maintenance requirement
Pressure rating up to PN 6
Operating temperatures up to 1100 °C (2000 °F)
Nominal diameters up to 5000 mm (200 inch)
Other sizes or operating conditions on request

Shut-off Valve

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
