Check Valve designed to protect your pumps and network against flow inversion, ideal for area where high pressure losses make powerful pumps necessary and quiet operation particularly important.
Applications :
- Wastewater and charged or high -viscosity fluids discharge stations.
Product benefits :
- Low head loss.
- Full bore ensured by complete removal of the flap, no risk of clogging.
- Tilted check valve reduces closing noise thanks to a shorter stroke.
- Broad valve seat reduces wear, even at high pressures.
- Flap fully encapsulated in moulded elastomer.
- Tight closure even under low back pressure.
- Removable bonnet allows maintenance without dismantling the product from the pipe.
- Horizontal or upward vertical mounting.
