Product Description

Wafer Type Duo-check Valve is to avoid unwanted back flow in a pipe.

Applications:
Water supply systems ( distribution, treatment etc. ), irrigation, heating systems, ship building, industrial processes ( liquids and gases ).

Service Temperature;
EPDM -15 C degree to +120 C degree ( Allowable temperature in continuous use -5~ +100)
NBR -10 C degree to +90 C degree ( Allowable temperature in continuous use 0~ +80)

The Duo-check valve has been designed for installation in flanged piping systems ( PN10, PN16, AS 2129 Table "E" etc. ). Suitable gaskets shall be used for sealing between valve and flanges.

Design:
- The self acting pivoting check valve of the double disc.
- Maintenance free. The design is compact and space saving.
- The superior closing response prior to flow reveal.
- The corrosion resistant springs are designed to quickly close the valve at zero flow to prevent undesirable pressure surges.
In the closed position the valve is tight shut off.
- It opens automatically when the flow starts again.
- The elastomer seat is vulcanized and bonded to the body casting.
- It is out of the flow path thus ensuring extended seal life. Spherical profiling of the seat ensures positive shut-off even at low pressures
And the area adjacent to the seat is also protected by the same elastomer material.
- Attention paid to the streamlining of the flow path is paramount if good flow characteristics are to be achieved.
- The saving of energy costs by selecting a check valve may be several times the initial cost of the valve.
- The use of these design features together with careful material selection makes a product with a high reliability and a low operating costs.
