Large diaphragm and a unique ‘double port’ design achieve a sensitivity of less than 5%.
Set pressure controlled by a weighted lever for settings below 1" (25 mm) WC; combination weighted lever and spring for settings up to 20" (50 mm) WC.
Double port design adds a dampening effect, allowing the valve smoothly to seek set pressure.
Rotary linkage design eliminates friction and drag.
Diaphragm chamber and valve body completely isolated to eliminate leakage.
Wide range of materials for service in most applications.
Easily adjustable setting for fine tuning in the field.
Can be set as close as 0.4" WC apart (blanket and recovery).
