- Available with FPM components (except GD-200H (C) sizes 65A to 150A).
- Available with pressure gauge.
- GD-200HS available for rinse water.
- The pressure balanced design of the valve allows the reduced pressure to be kept constant without being influenced by the inlet pressure.
- High wear resistance and durability of the valve seat made of stainless steel.
- The valve top is easily removable for inspection and maintenance.
- A rubber stopper prevents leakage when the valve is closed.
- The GD-200C is highly corrosion resistant due to the nylon coated inside and outside of the case.
- Installation in horizontal or vertical pipelines is possible. (For sizes over 100A, installation is carried out on a horizontal pipeline in the upper position).
