Description

The DIT-P corrosion-resistant diaphragm seal features a metal upper body combined with a plastic lower body, providing excellent chemical resistance and stable pressure transmission. Its dual-diaphragm overload structure withstands sudden pressure spikes, while advanced filling-fluid technology minimizes temperature and static-pressure effects. With a high-strength metal protective housing, the DIT-P is ideal for corrosive fluids, chemical processing, and environmentally hazardous media. Available in multiple diameters (70, 90, 130, 160 mm) and materials such as PP, PVC, PVDF, and PTFE, it supports various threaded and welded connections and can be paired with pressure gauges or transmitters—making it a reliable sealing solution for harsh and corrosive environments.
