EG41J Diaphragm Valve

The EG41J is a British Standard flanged rubber-lined diaphragm valve specifically designed to control the flow of non-corrosive or mildly corrosive media. It finds extensive application in petrochemical, water treatment, and energy sectors. Its core feature is the isolation of the valve body from the drive components via a rubber diaphragm, achieving a glandless seal and zero external leakage.

Parameters

Key Technical Parameters

Nominal Diameter: DN15 to DN350.

Nominal Pressure: 0.6 to 1.6 MPa (Common models include EG41J-6, EG41J-10, EG41J-16).

Suitable Media: Water, steam, oil products, weak acids/alkalis, and particulate-containing fluids.

Operating Temperature:

Temperature range determined by rubber lining material, e.g., butyl rubber (IIR) ≤120°C, neoprene (CR) ≤105°C.

Structural Features

Valve Body Material: Cast iron, ductile iron, carbon steel, or stainless steel, lined with hard rubber, butyl rubber, etc.

Seal Design: EPDM rubber diaphragm eliminates packing gland, preventing media leakage.

Flow Path Optimization: Fully rubber-lined flow path minimizes pressure loss; diaphragm allows for quick replacement.
