Overview

Q41 ball valve is suitable for controlling the opening and closing devices of various pressures, temperatures, and media in medium and small diameter pipelines to connect or cut off pipeline media; By relying on medium pressure to press the sphere onto the outlet valve seat, its usage pressure and diameter are subject to certain limitations Adopting 90 Transmission, therefore the switch is convenient and quick, and can be quickly opened and closed

1、 Q41F Gas Ball Valve Application and Performance Specification

Q41 typeball valveSuitable for controlling the opening and closing of pipeline media under various pressures, temperatures, and media for medium and small diameter pipelines; Press the sphere onto the outlet valve seat by relying on the pressure of the mediumball valveIts usage pressure and diameter are subject to certain limitations Adopting a 90 ° transmission, the switch is convenient and quick, allowing for quick opening and closing

2、 Q41F Gas Ball Valve Operating Principle and Structural Description

1ball valveThe channel is flat and smooth for pipeline cleaning, and can transport media such as slurry and solid particles

2. Using PTFE (Teflon) and other materials as seals, it has good lubrication and elasticity, low friction with spheres, and long service life

3. Quick opening and closing, simply rotate the sphere 90 ° for convenient and quick opening and closing

4.ball valveThe fluid resistance of the ball valve is small. When fully opened, the cross-sectional areas of the ball channel, valve body channel, and connecting pipeline are equal and straight, and the medium flows through the ball valve, which is equivalent to flowing through a straight pipe. Among all types of valves, the fluid resistance of the ball valve is the smallest

5ball valveEquipped with manual, worm gear drive, pneumatic, and electric (explosion-proof) options, it can achieve remote automatic control and meet the various operational requirements of users

Note: For valves with a diameter of ≥ DN200, Q347 fixed ball valves should be used.
