1. Product Overview

The accumulator shut-off valve is one of the accessories of hydraulic one bag accumulator, mainly used for safe shut-off and unloading, and also provides convenience for maintenance and replacement. The main valve structure is a hydraulic balance cone valve type, which has the characteristics of small operating torque and reliable sealing. According to the connection method, there are three types of accumulator globe valves: straight through, right angle, and three-way threaded connection. The XJF type accumulator globe valve is a high-quality accumulator globe valve independently developed by Asahi Hydraulic based on foreign data. Its main valve core is a hydraulic balance cone valve type, and this valve is designed with a discharge port specifically for the disassembly of the accumulator, which can replace imported accumulator globe valves.

　　2. Functional features

Used to achieve the functions of on/off, pressure relief and oil release between the accumulator and the system, while maintaining the pressure setting value in the system. The specific principle is as follows: when the pressure exceeds the set value, the shut-off valve opens to prevent system overload. Especially for energy storage devices installed in closed systems, shut-off valves can prevent the harm caused by sudden pressurization of external loads to the system, making them indispensable..
