DH
The DH range of quarter-turn hydraulic vane dampers are engineered to provide a simple, reliable solution to inherent problems often seen in swing check valve applications: namely down line surges from rapid disc reseating and excessive valve wear due to the disc flutter produced at some flow rates.
The rugged design features a self-contained hydraulic system that incorporates an easily adjusted valve for simple yet precise throttling controlin both directions. This closed loop hydraulic circuit protects the valve from potential valve contamination.
