KC8112Q pneumatic diaphragm cage single seat control valve

The single seal type is suitable for the medium with strict leakage requirement and small pressure difference. The double seal type is suitable for medium occasions with loose leakage requirements and large pressure difference.
KTJ5108Q pneumatic diaphragm cage type single seat control valve is a kind of high performance single seat control valve. The solid sleeve protects the valve body from internal evaporation and cavitation damage. Good earthquake resistance and low noise. With top guide structure, the valve has compact structure and good streamline of valve passage, which makes the pressure drop loss small, flow large and adjustable range wide. It is suitable for the situation where high pressure difference is easy to cause internal evaporation and cavitation.
