It features a ductile iron body. Rated to 250 psi and 33°F to 140°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThe ZW209BP Pilot Operated Pressure Reducing Valve or Automatic Control Valve (ACV) with low flow bypass is utilized in multiple residential and commercial applications where steady downstream pressure is required, and prevents chattering of the main valve from 0 to 10 GPM. The ZW209BP pilot assembly allows the main valve to modulate between closed and open for a constant downstream pressure, and seals shut after reaching the pilot setting to prevent possible downstream damage. Internal and external epoxy coating offers corrosion-resistance, while the isolation valves and pressure gauges provide easy setup, maintenance and repair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEpoxy coating of internals and externals protects against corrosion\u003c\/li\u003e\n\u003cli\u003eInlet and outlet pressure gauges, wye strainer, and isolation valves come standard and provide for quick and easy maintenance or repair\u003c\/li\u003e\n\u003cli\u003eReactive pilot assembly ensures constant downstream set pressure\u003c\/li\u003e\n\u003cli\u003eIdeal for accommodating both high and low flow rates\u003c\/li\u003e\n\u003cli\u003e150 class flanged, 300 class flanged, grooved, and threaded end connections available for versatile installation\u003c\/li\u003e\n\u003cli\u003eGlobe, reduced port globe, and angle bodies available\u003c\/li\u003e\n\u003cli\u003eANSI\/AWWA C530\u003c\/li\u003e\n\u003cli\u003eMeets the requirements of NSF\/ANSI 61\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat sets the downstream pressure?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA pilot valve on the discharge side senses downstream pressure and modulates the main diaphragm valve to hold it within a narrow band regardless of flow rate.
