Diaphragm valves are ideal for processes that require precise flow throttling. They feature a weir-style design that ensures there is no dead space in the valve. This is extremely well suited to abrasive slurries, high-purity applications and potential off-gassing chemicals such as sodium hypochlorite. Styles range from compact and direct acting to high-end industrial designs with numerous features and benefits. IPEX diaphragm valves come in many material, body-style and diaphragm options. The valve itself is comprised of three elements: the valve body, diaphragm and sealing bonnet. When compressed air enters the bonnet, the diaphragm is pressed against the bodyins weir, interrupting the air flow. This pneumatic diaphragm valve bonnet assembly provides an added layer of protection. For normally closed (NC) operation.
