A ductile iron water flow indicator, also known as a flow meter or flow indicator, is a device used to visually monitor and measure the flow of water in a pipeline or water distribution system. It provides a visual indication of water movement.
Types Of Check Valves
Ductile iron valve Check-type is one-way gates that prevent water from flowing back down the pipe after it’s been pumped. The pressure rating check valve is the differential pressure between the inlet and outlet, at which an initial flow is passing through the valve. Here are some examples of ductile iron check valves and their pressure ratings:
- Silent check valves – Have a ductile iron body, bronze plug, 316 stainless steel spring, and a working pressure rating of 250 psig
- Series 2100 Resilient Seated Check Valve – Manufactured from ductile iron meeting or exceeding ASTM A536, and rated for 250 psig cold water working pressure
- RD Series Check Valve – Has a ductile iron body in ASTM A-536 Grade 65-45-12, and a 250 psi rating
- Check Valves – Ductile Iron: Has a working pressure rating of 300 PSI
When Ductile Iron Water Flow Indicator With Pressure Rating Check Valve?
When considering the use of a indicator/ pressure rating check valve in conjunction with a ductile iron water flow indicator, several factors need to be taken into account:
- Pressure Rating: Check valves are designed to prevent backflow in a piping system. The pressure rating of the check valve should align with the maximum operating pressure of the system.
- Flow Requirements: Water flow indicators are typically used to visually monitor the flow of water in a pipeline. They are not specifically designed to regulate or control pressure. Check valves, on the other hand, are used to ensure unidirectional flow and prevent backflow.
- System Design: The need for a pressure rating check valve in conjunction with a water flow indicator depends on the specific design and requirements of the water distribution system.
Benefits Of Ductile Iron Water Flow Indicators
- Construction: Ductile iron water flow indicators are typically made from high-quality ductile iron.
- Clear Viewing Window: The flow indicator is equipped with a transparent viewing window, usually made from glass or a durable plastic material.
- Flow Rate Measurement: Some ductile iron water flow indicators may include markings or a scale on the viewing window.
- Easy Installation and Maintenance: Ductile iron water flow indicators are designed for straightforward installation and maintenance.
