2、 Detailed information

Product Overview

The wedge gate valve is a flexible wedge gate structure with full bore design, online maintenance, reliable sealing, easy opening and closing, and no need for daily maintenance. It plays a role in guiding/cutting pipelines and is suitable for media such as oil, gas, water, steam, etc. It is widely used in industrial fields such as power, petroleum, chemical engineering, metallurgy, mining, sewage treatment, and steam pipelines.

Design and inspection can comply with standards such as API 600, API 602, ASME B16.34, GB/T 12234, JB/T 7746, API 598, GB/T 26480, etc. Fire safety design meets API 6FA requirements, NACE anti-corrosion and acid resistance are optional, and API 624 low leakage is optional.

Main Features 

①Full bore design

② Welded on seat (small diameter integral seat), bi-directional sealing

③ Welding stainless steel, hard alloy, etc. on the sealing surface, selected according to the working conditions and user requirements

④ Special sealing design, less erosion by medium, good wear resistance and scratch resistance

⑤ Fireproof, anti-static, and anti valve stem spray
