Description

A ¾-inch (22 mm) high-pressure ball-valve-piston assembly combines the compact size of a ¾″ connection with the robust design needed for demanding applications. It features a piston-type actuation mechanism inside a ball-valve body, enabling reliable shut-off and high pressure tolerance — for instance, one version is rated up to 6 000 psi (≈ 414 bar) for the ¾″ size. The internal components (like ball, seals and housing) are engineered for durability under repeated cycles and aggressive media, making this kind of valve suitable for oil, hydraulic, steam or chemical systems rather than simply low-pressure water lines. It’s typically sized as ¾″ (ISO/BSP/NPT) which corresponds to about 22 mm nominal bore, hence the “3/4″ 22 mm HP” descriptor. When selecting such a valve, ensure it’s rated for your working pressure, temperature and media, and that the material (steel, stainless, seals) is compatible with your system — a mismatch here is the most common source of failure.
