  – Sealing : 255 PSI/17.6 Bar
  – Shell : 350 PSI/24 Bar
• Basic Design : BSS 5155/ISO 5752

DESIGN FEATURES :

1. 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 minimize pressure loss
• Minimize installation space and time

1. Valve Plates

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

1. Springs

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

1. Shaft

Heavy duty corrosion resistant construction
