Advantages of Large-Caliber Rod‑Type Cross‑Expansion Filter Pipes

The large-caliber rod‑type cross‑expansion filter pipe is a filtration device used in piping systems. It is typically installed at the inlet of equipment such as pressure reducing valves and relief valves to remove impurities from the medium and ensure the normal operation of valves and equipment. Its core functions include sedimentation, coarse filtration, and rod‑type expansion and adjustment, with a detachable filter cartridge design that enables convenient maintenance.

What is the difference between soft-sealed and hard-sealed flanged butterfly valves?

Soft sealing: Mostly adopts a centerline design, relying on the deformation of elastic materials to compensate for irregularities on the sealing surfaces; the structure is simple. Hard sealing: Typically employs single-eccentric, double-eccentric, or triple-eccentric designs, leveraging the metal wedge effect to enhance sealing performance, with high requirements for machining accuracy.
