SIERRA model 7500 is an eccentric disc seated – double eccentric – butterfly valves. Valve body and discs are designed to provide minimal flow resistance. Precise tightness is ensured on both sides. The double eccentric effect enables the rubber sealing ring to separate easily from the body seat, results in a cam like motion to lift the seat from the seal during the first degree of opening, there by reduces the opening resistance, wear and improves the service life of the valve seat. The sealing ring can be easily changed in pipeline without disassembling the disc. 7500 BFV model is suitable for high-pressure waterworks applications, it is an excellent valve for isolation purposes, and it might also be used for throttling purposes under certain conditions

Sierra sewage air valve series 6600-PP Are Hydromechanical devices designed to automatically release or admit air during pipeline filling, draining, or operation of a water pipeline or system. The safe operation and efficiency of a pipeline are dependent on the continual removal of air from the pipeline.
The model 1100/S Pressure Reducing Valve is a hydrauli-cally operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure, Thanks to a Sole-noid Control, the Valve will also open or close in response to a signal
Sierra water air valve series 6400-PP Are Hydromechanical devices designed to automatically release or admit air during pipeline filling, draining, or operation of a water pipeline or system. The safe operation and efficiency of a pipeline are dependent on the continual removal of air from the pipeline.
