DESIGN FEATURES
A. Body
ONDA exclusive body design offers these features :
Compact wafer style one piece design.
 No leakage to atmosphere is insured due to unique
design which eliminates through holes and pipe
plugs in the body.
Maximum flow area minimizes pressure loss.
 Minimizes installation space and time.

B. Valves Plates
Open to a full 90° offering a streamlined flow resulting in minimum pressure loss.
The dual plate design produce maximum strenght with minimum opening and closing time.

C. Springs
Torsion springs assist valve plate closure preventing flow reversal.
Consistent valve response insures against salmming and water hammer.

D. Shaft
Heavy duty corrosion resistant construction.
