Working Principle:
When the liquid lever reaches the set height, the valve closes automatically, when the liquid lever drops to a certain height, the valve automatic fills water.

Installation Instructions:
1\ The valv's rated paramaters should match the equipment's. Make Sure that the valve's rated flow satisfies the actual demand;
2\ The installer must be trained or experienced so as to operate the installation correctly;
3\ A thorough check after installation is needed to ensure no errors;
4\ A thorough cleaning before installation is needed(chemical reagent can be applied of it is necessary) to ensure that there is not any rusting or dirt in the pipe, All the filters must be removed before washing to keep the pipe smoothly open;
5\ When beginning to wash the system, it is suggested to install the valve on a temporary pipe. After finishing system cleaning, move the valve back and install it on the system’s pipe;
6\ This product should not be used when the fluid medium has high viscosity(contains much grease or mineral oil), or under corrosive circumstances;
7\ Use flange and the corresponding bolts that meet the standard to connect the valve;
8\ The direction of flow must accord with the direction of the arrow head on the valve body;
9\ For the size below DN200, the main valve can be installed horizontally or vertically, but horizontal installation is better. The size above DN200 only can be installed horizontally.
