Corrosion-Resistant Flow Control

Diaphragm Valves

Hitech Valves manufactures high-quality Diaphragm Valves designed for corrosive, abrasive, and slurry-based applications where contamination-free flow is essential. Available in Weir Type and Straight Through Type designs, our diaphragm valves provide bubble-tight shutoff and smooth throttling performance without direct media contact with the valve body’s moving parts.

Constructed using CI, DI, SG Iron, Cast Steel, Stainless Steel, and lined options such as Rubber, EPDM, Neoprene, PTFE, and PVDF, these valves offer excellent resistance to chemicals, acids, and high-purity media. Pressure ratings typically range from PN6–PN16, with temperature capability up to 150°C–200°C, depending on lining material.

Manufactured according to IS Standards and BS 5156, Hitech Diaphragm Valves are ideal for chemical processing, water treatment, pharmaceuticals, mining slurries, and effluent management systems requiring highly reliable, maintenance-friendly flow control.
