WPV
slANted seat check valve
WPV’s Slanted Seat Check Valve was designed for the water industry, taking into account the best available design with 20° slanted seat, exceeding the requirements of EN 593. The disc is streamlined by computer-optimisation for low headloss.

Features
- Functional light design.
- Smaller installation space requirement.
- High grade protection against corrosion.
- Field approved safe design.
- Low head loss.
- Variety of material application.
- Low torque requirements.
- Low number of turns per stroke.
- Sealing in both directions available (optional).
- Easy replaceable o-ring shaft seals.
- Best combination for a check valve is high eccentricity with less stroke due to slanted seat.
- Optimum closing of sealing ring into the body seat.
- Important reduction of the sharing strains of the sealing ring, due to the high eccentricity.
- Complete relief of sealing ring in open position.
- Sealing ring is not interrupted by shaft bearings.
- Sealing is easily replaceable in open position.
- Replacement of sealing is very economical and can be replaced without dismantling the valve.
- Possible to make valves for higher working-pressures (PN 25, PN 40).
- No risk of disc flutter (vibrations) by means unbalanced disc load.
- Dashpot damper is applicable.
How the Valve Operates
Designed specifically for corrosive applications. The body and seat are designed to assure non-clogging shut-off/on suspended solids. The valve can be manufactured with replaceable sleeves.
Applications
The valve is suited for pumping stations, treatment plants, reservoirs, pipelines, power stations, desalination plants & industrial applications.
