The ultra-high pressure automatic back pressure valve "L.TEX9220 type" has eliminated the drawback of traditional valves that, while having high pressure resistance, have a large internal volume leading to significant contamination and difficulty in use. It detects signals from an integrated pressure sensor and smoothly opens and closes the valve linked to a ball screw using a micro-stepping stepping motor, thereby suppressing pressure fluctuations. 【Features】 - Controllable pressure up to the ultra-high pressure range of 100 MPa. - Volume of 20 μl or less, with consideration for contamination suppression. - An optional heating head jacket is available to prevent freezing at the head section. - Temperature control during installation can be performed from the panel of the power supply unit. *For more details, please contact us or download the catalog.

The back pressure valve is generally used to maintain a constant pressure in the flow path, such as from the outlet of a high-pressure pump to a reaction vessel, in applications like supercritical reactions. Conventional manual back pressure valves are simple devices but are large and heavy, and due to their significant internal dead volume, extracts tend to accumulate inside, leading to contamination issues. Our compact manual back pressure valve, the 'L.TEX9205M model', was developed to address these shortcomings. 【Features】 - Diameter of 28 mm (compact) and weighs only 400 g (super lightweight) - Can be placed anywhere in the piping - Dead volume is also less than 20 μl - Designed with consideration for contamination suppression *For more details, please inquire or download the catalog.
