• Light weight engineered polymer components.
• Modular for easy removal of complete check from body.
• Easily disconnect spring tension for safe check servicing.
• Replaceable Silicone Rubber Elastomer Disk.
• Excellent resistance to fouling

Poppet Action

Features:

• Initial 25% of check stroke is that of a poppet check.
• Consistent static sealing
• Excellent resistant to fouling
• Reliable check closure
• Stable flow characteristics at lower flow rates

Swing Action

• Final 75% of check stroke is that of a swing check.
• Minimal friction loss at high flow rates.
• More linear flow path water through valve.

The Patented Bow-Seal™ Full Access Cover (US8844562) is pre-formed to cylindrical shape friendly to high fluid pressure. This allows the cover to be much thinner and lighter than traditional flat covers while still providing FULL and EASY access to Dual Action™ Check Modules.

Additional features include:

• Light weight
• Simple removal
• No sliding seals
• Full access to valve internals
• No cumbersome and heavy couplings
