What is the difference between AWWA C509 and C515?
Many Engineers question the difference between the AWWA C509 Standard and the AWWA C515 Standard for resilient seated gate valves. The AWWA C509 Standard was developed based on the physical characteristics of cast or gray iron while AWWA C515 was developed based on the more robust characteristics of ductile iron.
How much does a 10 gate valve weight?

What is resilient wedge gate valve?
FlowMaster resilient wedge gate valves are designed to control the flow of water in fire hydrant applications, but can also be utilized for other water distribution or sewer system applications. All valves are compliant with the Reduction of Lead in Drinking Water Act of 2011.
Can a gate valve be repaired?
A malfunctioning gate valve is not difficult to repair, but it is even easier to prevent. These problems are typically caused by mineral buildup, so you should fully close and open your gate valves every few months to clear potential problems.
What is the difference between a gate valve and a ball valve?
The main difference is in the operation. A gate valve moves a solid disk up and down to open/close the orifice. A ball valve rotates a ball (the orifice) with a bore in it 90 degrees to open/close the valve.
What is c509?
This standard describes iron-body resilient-seated gate valves with nonrising stems (NRS) and outside screw-and-yoke (OS&Y) rising stems, including tapping gate valves, for water supply service having a temperature range of 33° to 125°F (0.6° to 52°C).
What is AWWA C504?
Back to AWWA C504-15 Rubber-Seated Butterfly Valves. This standard covers rubber-seated butterfly valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with various body and end types, for fresh and reclaimed water having a pH range from 6 to 12 and a temperature range from 33° to 125°F (0.6° to 52°C).
What are the different types of gate valves?
Gate valves can be divided into two main types: Parallel and wedge-shaped.
What is a double disc gate valve?
Double Disc Type Gate Valves have parallel seats against which the wedge is driven when the gate is closes. This results in a tight seal between the disc and the seat. Variation of this design includes valves that depend on fluid pressure to force the disc against the seat.
Which is better gate valve or globe valve?
They offer more resistance to fluid flow, and have a high-pressure drop even when the valve is fully open. Globe valves generally seal better than gate valves and last longer. They are more expensive than similarly sized gate valves, but may be worth the extra expense in situations where throttling is needed.
