Overview
Oxygen pneumatic cut-off valves are widely used in general fluid media and process conditions, as well as compact automatic control systems in the petrochemical and textile industries.
Product Details
Oxygen pneumatic cut-off valvePurpose and Features
The pneumatic sleeve regulating valve has a small shape, light weight, high performance, and large capacity, and is a new generation of universal regulating valve products that comply with IEC standards.
It is widely used in the petrochemical and textile industries as a compact automatic control system for general fluid media and process conditions. This product consists of a new type of pneumatic multi spring thin film actuator and a low flow resistance sleeve.
Oxygen pneumatic cut-off valveThe characteristics are as follows:
1. Adopting a balanced valve core, the unbalanced force is small, allowing for a large pressure difference and stable operation.
2. The valve core has a large guiding surface, which can improve the oscillation caused by eddy currents and impacts, and reduce damage.
3. Reduce noise by about 10dB compared to ordinary single and double seat regulating valves.
4. The structure is simple and easy to assemble, disassemble, and maintain.
