SI TECHES SEMI AUTOMATIC EXHAUST VALVES SI TECH variable volume exhaust valves are designed to control the gas volume in the suit Desired gas volume is set by rotating the lid during the pre dive buoyancy check in the water Correctly set the valve will automatically vent gas as the diver ascends The setting can be easily over ridden by pressing on the valve lid to manually dump gas SI TECH Exhaust valves are designed to act as safety valves with a maximum overpressure at maximum setting of 40 Mbar with flow rate gt 100 N lit min For adequate insulation and buoyancy at surface a minimum pressure of 20 Mbar can be maintained for extended surface duration SI TECH exhaust valves are designed to be reliable pressure sensitive and easy to operate Optimum valve performance 1s obtained by following the instructions in the valve user s manual which is supplied to suit manufacturers Exhaust valve ORIGINAL The original reliable pressure sensitive and easy to operate 10100 Exhaust valve ORIGINAL SMALL guide ridge 10500 Exhaust valve ORIGINAL LARGE guide ridge More models are available to fit different suit material thickness The Original semi automatic exhaust valve designed in 1971 was produced 11830 11000 exclusively for Viking dry suits for almost two deccades obsolete obsolete SI TECH Exhaust valve Low Profile was introduced in the late 19801es 11000 and 11500 series were replaced b
