Product introduction

※ Product name: Fluorine lined swing check valve
※ Product model：H44F46-16C
※ Product specification：DN15-200
※ Shell material: carbon steel、304、316L
※ Lining material：FEP（F46）、PFA
First, product characteristics
Fluorine lined check valve (also known as check valve) the role of this type of valve is to allow the medium to flow in only one direction, and to prevent the direction of flow.
Second, the working principle
Lining check valve only allows media to flow in one direction and prevents fluid backflow. Usually, this valve works automatically, under pressure in one direction, valve disc opens, fluid flows in the opposite direction when fluid pressure and valve disc, PTFE valve ball weight, hand seat to cut off flow.
