The "Orifice Block (AOB)" is a product that consists of an orifice plate and a differential pressure extraction port integrated into a single structure. Due to the limited gasket seal area, it is suitable for use with medium to high pressure, fluids that are prone to leakage, and at high temperatures. There are types that are used by sandwiching between pipe flanges and types that are welded to piping. The differential pressure extraction methods include corner taps and flange taps. 【Features】 ■ Limited gasket seal area ■ Suitable for medium to high pressure, fluids that are prone to leakage, and high-temperature use ■ Requires long straight pipes before and after the installation part ■ Types that are used by sandwiching between pipe flanges and types that are welded to piping ■ Differential pressure extraction methods include corner taps and flange taps *For more details, please download the PDF or feel free to contact us.

The "Orifice Plate (AOP)" is the most common and widely used product in throttling mechanisms. It has a simple structure and high reliability, allowing for short delivery times and low-cost production. However, it has a large pressure loss among throttling mechanisms and requires long straight pipes before and after the installation section. Depending on the shape, there are concentric circles, eccentric, elliptical, quarter-circle, and rectangular types. The differential pressure extraction method for standalone use is D-D/2 tap and vena tap. 【Features】 ■ Simple structure and high reliability ■ Possible to produce with short delivery times and low costs ■ Requires long straight pipes before and after the installation section ■ Concentric circles, eccentric, elliptical, quarter-circle, rectangular ■ Differential pressure extraction method is D-D/2 tap and vena tap *For more details, please download the PDF or feel free to contact us.

The "Orifice Flange (AOF)" is a product composed of an orifice plate and an orifice flange with a differential pressure take-off, combined with bolts, nuts, and a gasket. The shape of the gasket seat can be flat face (FF), raised face (RF), or ring joint (RTJ), allowing for use under a wide range of temperature and pressure conditions. The connection method to the piping is welding, with options for butt welding and socket welding. The tapping method is flange tapping. 【Features】 ■ Gasket seat shapes include flat face, raised face, and ring joint ■ Usable under a wide range of temperature and pressure conditions ■ Connection methods to piping include butt and socket welding ■ Tapping method is flange tapping *For more details, please download the PDF or feel free to contact us.

The "Orifice Ring (AOR)" is a product composed of an orifice plate, a ring with a differential pressure extraction port, and a gasket. It is designed to be sandwiched between pipe flanges, making installation and replacement easy. Due to its structure, it has a larger gasket seal area, so it is mainly used in low-pressure lines of 2MPa or less. 【Features】 ■ Mainly used in low-pressure lines of 2MPa or less ■ Differential pressure extraction method is corner tap *For more details, please download the PDF or feel free to contact us.
