Potentially present hydrocarbons in the atmosphere can be a problem when attempting to make a controlled stop of an internal combustion engine.

These hydrocarbons may enter the engine air intake system producing acceleration and loss of speed control of the engine, with the subsequent risk of explosion or deflagration. Standard stopping methods eg. shutting of the fuel flow, may be quite useless, leaving the engine in an uncontrollable runaway situation.

The shut off valve allows the automatic closing of the engine’s air intake resulting in the shutdown of the engine and increasing safety in places such as offshore oil platforms, ship engine rooms and petrochemical refineries and plants.

For industries where combustible gas, vapours or dust can exist:

• Marine
• Oil & Gas
• Petrochemical
• Power generation
• Transport
• Mining

Conventional shutdown alternatives such as cutting off the engine’s fuel to prevent overspeed, can be ineffective. Only by installing shut off valves is it possible to ensure a fast and safe engine shut down.

Air Shut Off Valves
These valves have been designed and developed to solve the common and repetitive problems caused due to engine vibration and low resistance to high temperatures.

Many years of experience and collaboration with engine manufacturers has resulted in the development of the most reliable and safe valves existing on the market:

• High resistance to vibration
• Good resistance to high temperatures (after turbo installation)
• No high-pressure air leakage (up to 5 bar)

Manual, electric, pneumatic and hydraulic solenoid trip operating methods used.
