YFC-2N Type Automatic Flow Control Valve (per Household)

Auto Flow Control Valve

An automatic flow control valve per household limits the maximum flow, thereby distributing an appropriate flow to each place of use. It maintains the flow balance of each place of use by automatically adjusting the flow during the instrument’s constant flow rate operations, thereby stabilizing the overall system

Features

• Perfect Pressure-Balancing Type valve: it can be used independently from pressure changes, etc.
• Diaphragm operation method, instead of the usual cartridge method : less set flow variation.
• Variable flow control function : easy to change and adjust the set flow on the field, without disassembling.
• The employment of an optimal design for fluid flow reduces noise and vibration.
• Structure that allows a constant flow is only slightly affected by foreign substances and ensures easy disassembling and maintenance.
• Easy to remove foreign substances, thanks to an embedded strainer in the valve union.
• Easy to select a piping direction since both sides of the product are set up with unions.
