Diaphragm: Rubber
Valve disc: cast iron
Valve stem: carbon steel, stainless steel
Handwheel: Cast Iron

Test
Lining layer: Electric spark detection
Testing and inspection shall be conducted in accordance with GB/T13297 standard
Nominal pressure: PN (Mpa)
Valve body: PN × 1.5
Sealing: PN × 1.1

Purpose
G41J rubber lined diaphragm valve is designed for controlling non corrosive or generally corrosive media. The surface of the valve body cavity is either unlined or covered with various rubber options, suitable for different working temperatures and fluid pipelines.
Applicable temperature: ≤ 85 ℃, ≤ 100 ℃, ≤ 120 ℃, ≤ 150 ℃ (according to lining and diaphragm materials)
Pressure level: PN0.6, 1.0, 1.6

structural characteristics
G41J rubber lined diaphragm valve is a special form of shut-off valve;
1. Elastic sealed opening and closing components ensure no internal leakage;
2. The streamlined flow channel reduces pressure loss;
3. There is no stuffing box, so there is no leakage;
4. The valve body and cover are separated by a middle diaphragm, so that the valve cover, valve stem and other parts above the diaphragm are not corroded by the medium;
5. The diaphragm is replaceable and has low maintenance costs;
6. The diversity of lining materials can be applied to various media and have good corrosion resistance.
