Check Valve Overview

Check Valves are found in almost every industrial application acting as one-way or non-return valve.Check Valves.are simple device,perform a vital function by preventing reverse flow, therefore preventing damage and ensuring efficient operations.For example,reverse flow can result in water hammer.This phenomenon can see repeated extreme pressure surges in connected pipework,valve and pumps that fatally damage or rupture the system and its pipework.Even if a failure does not occur immediately the repeated impact of water hammer can promote fatigue that may also ultimately result in a loss of system integrity.

Dual Plate Check Valve They are low cost, and have low head loss characteristics when fully open. But because of the long stroke and inertia of the disc, the traditional swing check valve may slam in vertical pipe installations. These valves are therefore sometimes outfitted with a lever and weight accessoryy. They can handle liquids with solids such as wastewater.

Features of Dual Plate Check Valve:

• Small in size,light in weight,compact in structure,easy in maintenace.
• Two torsion springs are used excreting on each of the pair valve plates.Which close the plates quickly and automatically
• The quick-close acting prevents the medium from flowing back and eliminates water-hammer effect
• This valve is short in length,so that it is rigid and easy to mount
• It is wasy to install on pipeline which is laid horizontally or vertically
• This valve is tightly sealed without leakage under the pressure water test
• Safe and reliable in operation,high interference-resistance
