- Reduced flap weight minimises slamming and water hammer
- Dual-plate (double-disc) lug-type wafer check valve
- Lug-style body with threaded bolt holes for end-of-line installation
- Lifting eye/lug at top of body
- Stainless steel disc plates with visible centre hinge pin
- Heavy-wall cast body construction
