2、 Detailed information

Product Overview

The pressure balanced plug valve adopts a side pressure balanced structure, and the valve body adopts a cast structure with a unique appearance. It has excellent performance such as long service life, bidirectional zero leakage, fire and anti-static, corrosion resistance, and labor-saving operation. This product has significant features such as beautiful appearance, simple structure, good sealing performance, long service life, wide applicability, and low operating torque. It has the function of conducting/cutting off pipelines. Mainly used for long-distance natural gas pipelines and station control systems, such as bypass and venting, especially suitable for harsh environments.

Design and inspection can follow standards such as API 6D, API 599, ASME B16.34, ASME B16.5, and API 6FA. Fire safety meets the requirements of API607/API 6FA and has been tested and certified. NACE anti-corrosion and acid resistance, as well as ISO 15848 low leakage options.
