Key Features

• Tongue and Groove Seat Design — The rubber seat features a precision-molded tongue that locks into a matching groove machined into the valve body. This mechanical interlock prevents the seat from shifting, rotating, or extruding under pressure differential, providing positive seat retention even in vacuum service.
• Soft Seat (EPDM/NBR) — Fully molded soft rubber seat provides bubble-tight Class A shut-off per API 598. Available in EPDM (water) or NBR (oil) compounds.
• Aluminum Lever Handle — Lightweight, corrosion-resistant aluminum alloy lever with ergonomic grip. 10-position locking plate provides 50° incremental disc positioning. Lever length optimized for comfortable manual operation.
• Wafer Type Design — Compact, lightweight body installs between ASME B16.5 or EN 1092-2 flanges. Centering lugs ensure proper alignment during installation.
• Ductile Iron Body — ASTM A536 Grade 65-45-12 ductile iron with electrostatic epoxy coating (min 80 microns) for corrosion protection.
• Blowout-Proof Stem — One-piece stem with undercut shoulder design prevents stem ejection under pressure.
• 100% Pressure Tested — Every valve hydrostatically tested at 1.5x rated pressure per API 598.

Technical Specifications

Aluminum Lever Advantages

• Corrosion resistant — Anodized aluminum alloy will not rust in outdoor or humid environments

• 10-position locking — Positive lock plate with 50° increments for flow regulation or isolation
• Ergonomic grip — Comfortable rubberized grip surface for gloved operation
• Visual indicator — Lever position clearly shows valve open/closed status from a distance

Applications

• Water treatment and filtration systems
• HVAC chilled water and hot water
• Irrigation and agricultural supply
• Industrial process water
• Compressed air and non-corrosive gases
• Swimming pool and spa circulation
• Fire protection sprinkler systems
