1、 Structural characteristics of ridge diaphragm valve

Ridge diaphragm valve is a special form of block valve: 1. The opening and closing parts of elastic seal ensure no internal leakage; 2. Streamlined flow passage makes the pressure loss small; 3. There is no stuffing box, so there is no leakage; 4. The valve body and cover are separated by the middle diaphragm, so that the valve cover, valve rod and other parts above the diaphragm are not eroded by the medium; 5. The diaphragm can be replaced and the maintenance cost is low; 6. The diversity of lining materials can be applied to various media, and has the characteristics of high strength and good corrosion resistance.

2、 Materials of main parts of ridge diaphragm valve

Valve body: cast iron, ductile iron, carbon steel, stainless steel bonnet: cast iron, ductile iron, carbon steel, stainless steel lining: unlined, rubber diaphragm: rubber disc: cast iron stem: carbon steel, stainless steel handwheel: Cast Iron

3、 Application of ridge diaphragm valve

This valve is specially used to control non corrosive or general corrosive media. The surface of the inner cavity of the valve body is unlined or covered with various kinds of rubber, which is suitable for different working temperatures and liquid pipelines.

Applicable temperature: ≤ 85 ℃, ≤ 100 ℃, ≤ 120 ℃, ≤ 150 ℃ pressure grade: PN (MPA) 0.6 1.0 1.6
