Over the years, JK-Matic has been on the traditional diaphragm to improve and innovate. Between 2012 and 2013, JK-Matic successfully developed the diaphragm valve into eight series, dozens of specifications, it can be used in a wider area of water treatment applications.


JK-Matic diaphragm valve with unique upper and lower dual control chamber design, control flow independent of the fluid chamber, so that the valve is more flexible in control, reliable and durable, completely eliminate the single-chamber control valve (such as V valve) may exist switch Not working, lax hidden. In the material, JK-Matic diaphragm valve body and valve cover used glass fiber reinforced materials, making the valve high strength, long life, corrosion resistance (can be used for desalination system). The diaphragms using special treatment of enhanced rubber molding, long life, high anti-fatigue strength. At the same time, the valve body within the Y-type fluid channel design reduces the pressure loss of the valve to improve the water flux。


Working pressure:  0.1 - 0.8 MPa

Working temperature : 4 - 50°C
