Product Description
The SWING check valve is a non-return valve that can be flexibly used for water and sewage. Featuring a 93 % opening value, it guarantees an extremely low zeta value, a head loss of less than 8 mbar in the fully opened position and a high degree of cost-effectiveness. Moreover, it is thereby scrapable in flow direction. The ball-shaped bearing pin ensures self-centring of the valve disc in the body seat which always guarantees sealed closure, even at low back pressures. The shaft is supported in the cover, thereby medium free, permanently smoothly running and can easily be replaced.
Apart from an internal shaft, the SWING check valve is also available with an external shaft including lever and weight. This design can be equipped with a basket guard to prevent accidents in the area of the lever. A conversation of internal to external shaft with lever and weight can also be done later without mounting the valve from the pipe. And in addition, the SWING checkvalve is also available with lever and weight on both sides. The seat ring in the body is made of stainless steel, which, in conjunction with the inside and outside epoxy-coating of the body parts (with the thickness of 250μm) it´s an optimal protection against corrosion.
