The Cla-Val Model CRD-7 Pressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure with our unique design. This valve is an accurate regulator capable of holding downstream pressure to a predetermined value, regardless of upstream pressure fluctuations. Water distribution systems: Use CRD-7 Pressure Reducing Valves at service connections in a high-pressure distribution zone. Depending on flow requirements, CRD-7s may be installed in parallel. One CRD-7 provides desired outlet pressure while the second valve handles low flow conditions. If necessary, additional CRD-7s can be added for more flow capacity. The CRD-7 is also ideal for a low flow bypass around a larger Cla-Val 90 Series Pressure Reducing Valve.
