Silent Check Valve
Spring assisted closure available for short valve lengths.
Compact and light design is an effective solution for smaller sizes. In spite of the short length our design has double bearings for guiding.
Certified powder epoxy coating, which is safe for drinking water.
Available sizes are DN 50 to DN 1200 with pressures PN 10-40.
Venturi Type Nozzle Check Valve
Lower head-loss due to a longer body with specialized streamline flow path. Spring protected in an enclosed chamber.
One long bearing provides reliable operation. The option of double bearings can be applied for large sizes and high working pressures.
Certified powder epoxy coating, which is safe for drinking water.
Available sizes are DN 250 to DN 1200 with pressures PN 10-40.
Ring Type Nozzle Check Valve
The Ring Type Nozzle Check Valve disc is ring shaped in such a way that the flow goes around the disc and through the center hole.
This feature balances forces on the disc in both flow directions and in turn gives the opening and closing of the disc a smoother characteristic
Light Disc Nozzle Check Valve
The Light Disc Nozzle Check Valve has a HDPE disc where the flow goes around and through the disc ports.
Although this lightweight disc material is quite weak, it is supported by a wide seating frame for it to withstand substantially more pressure.
