106/206-HC – Singer Hydraulic Check Valve
The 106/206-HC Hydraulic Check Valves are based on the Singer Type 106-PG or 206-PG main valve. The valve functions as a two position valve – either fully open or fully closed. Under normal flow conditions, the valve opens as the higher inlet pressure lifts the inner valve assembly and the fluid in the upper chamber is discharged to the lower pressure, downstream side of the valve. When pressure is reversed, the now higher downstream pressure is applied to the upper operating chamber as flow reversal occurs. The diaphragm/inner valve assembly moves down and the valve closes tightly.
- Drip-tight seat
- Independently adjustable opening and closing speed controls
- Allows one way flow only
