Fully welded ball valve Wenzhou valve Q61F DN40 integrated fully welded ball valve manufacturer direct sales

Description :

　　1. Product Overview

　　The fully welded ball valve body is a one-piece welded ball valve formed by pressing seamless carbon steel pipes. Due to the fact that the valve seat is composed of a carbonized PTFE sealing ring and a disc spring, it has strong adaptability to changes in pressure and temperature, and will not produce any leakage within the marked pressure and temperature range.

　　Widely used for urban gas: gas output pipelines, main and branch pipelines, etc; Central heating: large heating equipment output pipelines, main lines, and branch lines; Heat exchanger: opening and closing of pipelines and various circuits; Steel plant: various fluid pipelines, exhaust gas discharge pipelines, gas supply pipelines; Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipelines.

　　2. Performance characteristics

　　① One piece fully welded ball valve, without external leakage or other phenomena;

　　② Adopting a floating ball structure, the inclined elastic gasket ensures that the sealing ring is tightly pressed on top of the sphere, even in unstable pressure situations, the valve can ensure tightness;

　　③ Due to the fact that the valve body material is the same as the pipeline material, there will be no uneven stress, and there will be no deformation due to earthquakes or vehicles passing through the ground. The pipeline is resistant to aging;

　　④ The sealing ring body is made of RPTFE material with a carbon content of 20%, ensuring complete leak free operation;

　　⑤ Directly buried fully welded ball valves can be buried underground without the need to build large valve wells. Only small shallow wells need to be set up on the ground, greatly saving construction costs and project time;

　　⑥ The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline;

　　⑦ The processing of the sphere is tracked and detected by advanced computer detectors, with very precise machining accuracy and easy operation;

　　⑧ No maintenance, adjustment or lubrication required, easy to install, valve body does not contain heavy and unreliable castings

　　3. Standard technical parameters
