Frequently Asked Questions:

Q. What is the installation orientation of this valve?

A. Milwaukee 1856-600 silent check valve can be installed both horizontally and vertically. Make sure the hinge pin on the swing checks is horizontal and the stem is in a vertical position.

Q. What is a non-slam check valve?

A. Non-slam check valves, also known as silent check valves, are designed to potentially reduce the water hammer effect and prevent the backflow contamination or reverse fluid flow.

Q. Where are non-slam check valves found?

A. They are ideal for applications in steam condensate systems, water treatment boilers, oil or process lines and hot & cold water systems.

Q. What is the water hammer condition?

A. Water hammer is caused in fluid lines when the flow abruptly stops. This sudden change in flow rates causes the fluid pressure to move upstream, create a reflect-return movement and an increased pressure pulse. It mostly occurs in high-pressure water lines when the outlet tap is turned off suddenly or by a quick-acting solenoid valve. Common signs for this situation are rattling in the pipe or loud thud-like sounds.
