900GS-16
Stainless Steel Dual Chamber - Full Port with Mechanical Check Feature
900GS-16 (Globe) and 900AS-16 (Angle) Series are Stainless Steel, full port, dual chamber basic valves that incorporate a two-piece telescoping disc and diaphragm assembly. When pressure is applied to the upper diaphragm chamber and released from the lower diaphragm chamber, the valve travels to a closed position. When pressure is applied to the lower diaphragm chamber and released from the upper diaphragm chamber the valve travels to a full open position. he lower portion of this two-piece assembly is a mechanical check feature, which acts independent of diaphragm position or pilot control system, and provides immediate check action when flow ceases. Stainless Steel construction provides superior corrosion resistance, a lightweight alternative to conventional heavy iron valves, extended diaphragm life, and reduced frequency and labor costs associated with traditional maintenance repairs.
Features
- Valve opens and closes as commanded by the pilot control system
- Two-piece disc and diaphragm assembly is the only moving part within the valve
- Mechanical check feature provides immediate check action when flow ceases
- Lightweight Stainless Steel construction reduces corrosion, diaphragm wear, and labor frequency and costs
