Features
- Short face-to-face dimension facilitates installation, handling, storage and pipeline layout
- Dual-flap design reduces fluid resistance compared to single-disc construction
- Each flap is half the size of a full single disc, halving the rotation radius and reducing travel time to closed position by up to 50%
- 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 centre hinge pin
- Heavy-wall cast body construction
Description
Lug-type double plate (dual disc) check valve for pipeline installations where short face-to-face dimensions are required. The dual-flap configuration reduces fluid resistance and travel distance to the closed position, minimising water hammer. Available in sizes NPS 8 to 60 (DN200 to DN1500) and pressure classes 150 to 900.
