title: Terminal gas-exhaust valve for a passive disposal system.
abstract: A one-way gas-exhaust valve for use in passive disposal systems is described. The valve is explosion-proof and it does not offer any resistance at gas flow rates of up to 30 litres/minute. The design of the valve minimises the influence of wind velocities on pressure fluctuation in the disposal system.
