Cast Iron Diaphragm Valve with Flanged End
Product Details
The Cast iron diaphragm valve features a flexible elastomer diaphragm that seals against the valve seat, providing a tight, leak-proof shut-off without metal-to-metal contact. Diaphragm valves are widely used in water, wastewater, chemical processing, and industrial applications where leakage resistance and corrosion performance are critical.
This diaphragm valve features a flanged end connection, offering straightforward installation and secure integration into pipeline systems built to standard flange dimensions. Manufactured according to recognized international pressure standards such as PN10/PN16 (or ASA 150#), it supports a broad range of nominal sizes from ½″ to 12″, accommodating diverse piping requirements.
Key design features include a non-rising hand wheel operation, smooth – straight through flow path and a flexible diaphragm that isolates the process fluid from moving components, effectively minimizing contamination and wear. This design makes the valve especially suitable for handling clean, corrosive, particle-laden or sensitive media in chemical processing, water treatment, pharmaceutical manufacturing, food and beverage, and general industrial services.
Key Features
Positive Leak-Free Sealing: Flexible diaphragm isolates the fluid from the valve’s internal moving parts, ensuring tight shut-off and minimizing leakage, even with corrosive or particulate media.
Flanged End Connections: Standard flanged ends (PN10/PN16 or ANSI equivalents) enable secure, easy installation and reliable integration with existing pipeline systems.
Versatile and Low-Maintenance Design: Simple hand wheel operation with smooth flow paths, corrosion-resistant sealing materials.
