▶ Special Feature 

● Simple Design

● Drip Tight Shut Off

● Adjustable the speed of Opening and Closing

● Preventing Back-flow

  Model 137-010 consists of Basic Valve(BALEM 130) and Two Flow Control Valve. The valve is installed at Outline of Pump to prevent Back flow caused by Back Pressure.

The valve is slowly opening to prevent sudden opening surges, When a pressure reversal occurs the higher downstream pressure is applied to the cover chamber through the control tube lines, and the valve closes drip tight.
