10KC8112Q 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.
C8104Q pneumatic diaphragm sleeve control valve is a common improved product. In addition to the common sleeve valve has good stability, versatility, easy maintenance and other advantages; It also has the advantages of small volume, light weight and large flow coefficient. 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.
Main performance index:
Leakage rate: hard seal grade IV, less than 10 "return difference of rated flow; without positioning seat, less than 3% of full stroke; Basic error: without positioner, less than + - 5% of full stroke; Dead zone: without positioner, 3% of the total travel of the second Olympic space;
Soft seal grade VI, less than 10 "of rated flow with positioner, less than 1% of full stroke with positioner, less than + - 1% of full stroke with positioner, less than 1% of full stroke with positioner.
