Butt Welded Check Valves

The main advantages of the Hanno Valve high quality butt welded check valves include its excellent sealing performance, simple structure, compact size, lightweight, and low fluid resistance, making it suitable for various pipeline systems. The valve opens and closes based on the medium's pressure: when the medium flows forward, the valve disc is lifted by the fluid, allowing passage. When the flow reverses, the disc closes under its own gravity and the fluid's reverse thrust, effectively preventing backflow.

Product Description

The Hanno Valve butt welded check valve features an internal rocker arm rotary opening structure, with all opening and closing components installed inside the valve body, preventing external leakage except for the sealing gasket and sealing ring at the middle flange. The rocker tube and valve release connection use a spherical connection structure, providing the valve with 360-degree freedom and micro-position compensation. This valve is ideal for clean media, such as water, steam, oil, nitric acid, acetic acid, and urea, but not suitable for media containing solid particles or high viscosity. It is commonly used in pipelines for industries such as petroleum, chemicals, pharmaceuticals, fertilizers, and electricity.
