The inner workings of the valve were developed and designed by GFPS
Research & Development to comply with clear market specifications.
The valve must be operable in any installation position and all the
while offer greater safety. Efficiency was also improved and the wear
and tear on moving parts reduced, so that costs for users could be
lowered. These new products ideally meet the needs of our customers.
Instead of using a check ball, the new valves rely on a specially
developed double-guided cone. Its geometry is designed for optimal
flow and minimal pressure loss, thus significantly improving valve
efficiency and performance.
Our engineers have also adapted the profile seal for the new design. This seal has proven its effectiveness in the ball check valve type 360 for over 20 years. The sealing lip of the valve is flexible in the sealing zone, allowing the elastomer to ideally encompass the cone. The check cone has a spherical contour in the sealing zone. Should the cone be deflected, a leak-tight seal of the valve is guaranteed in the closed state.
