• Excellent vibration resistance

  Simultaneous-monolithically molded body with inserted metal core has high stiffness, preventing external leakage and seat leakage even against a strong external force.
  The boundary between PE and metal is firmly sealed with an O-ring and stiffener.

• Lightweight and compact

  Adoption of butterfly valve as the core valve reduced face-to-face dimensions and outer diameter comparable with EF joints, eliminating interference with other buried products during installation and maintaining almost equivalent weight to fully PE products.

• Excellent dust resistance

  Adopting highly dust-resistant special rubber as the disc seal in the dual eccentric structure (butterfly valve) provides excellent sealing performance.

• Dual eccentric structure
  

• Excellent operability

  Sealing by metallic core valve inserted to the body reduces fluctuation of torque regardless of external force or temperature change, providing stable opening/closing operation.
  A newly developed operating portion has direct-acting (90°C opening/closing) self-lock mechanism, eliminating a release-lock action during operation and enabling quick valve operation in case of emergency.

• Maintenance-free

  Adoption of self-lubricating disc seal rubber eliminates nuisance of sealant injection and maintains reliable valve performance for a long period of time.

• Various operational angles

  To respond to various handles, four operational angles are available for each size (48 x 48, 45 x 45, 40 x 40, and 35 × 28).

• Dissipation tube/waterproof specification (Optional)

  Types with a dissipation tube, convenient for bypass operation, gas diffusion, and gas pressure measurement, are available.
  Waterproof sheath sets that protect the valve operating portion from dirt, rainwater, and spring water, are also available.
