Required valve (desire 411)

The Varam Valve (Varaem 411) is a buoyant water level control valve with a ball valve type on/off structure that opens and closes by utilizing the weight of buoyancy and buoyancy to rotate the flow path on/off ball in the valve chamber. The purpose of controlling the liquid level in the tank.
Due to the full mechanical structure, the opening and closing of the valve is based on the rotation of the ball valve without a separate power supply and driving device, so the shutdown and operation of the valve are good and stable under high pressure. This product uses only corrosion/heat resistant materials for excellent durability and is easy to transport and install

Refer to standard piping diagrams when installing this valve.
Before installing this valve, be sure to remove foreign matter from the primary side piping.
Be sure to install this valve vertically, and a bleed pipe with vortex size H3 or larger vertically.
Install an alarm receiver in the management room for early detection of overflow accidents not caused by the valve.
Install this valve near the manhole for easy maintenance and other maintenance.
When installing this valve, do not hold the octagonal nut portion of the bonnet (part no. 2), but install it by the octagonal nut portion of the valve body (part no. 1).
When assembling the lever and pontoon, make sure that the pontoon is facing up and punch the guide tube according to the outer dimensions.
