MILWAUKEE VALVE 1856 - 600 Silent Check Valve, Globe Style, Cast Iron, 6 Inch Valve Size

Milwaukee 1856-600 silent check valve is preferred where noiseless operation is a primary concern. This silent check valve is essential in centrifugal pumps and HVAC systems to check backflow without any noise.

Working Mechanism:

• Milwaukee 1856-600 is a manually operated unit.
• Open the valve by turning the handle counterclockwise.
• The valve disc rises from its seat when the flow happens, allowing forward flow.
• The valve's spring compels the disc to close before the flow reverses (when the pump stops).
• Turn the handle clockwise to shut the valve.

Features:

• Milwaukee 1856-600 silent check valve regulates the uni-directional flow in a pipeline and avoids hindrance.
• This globe-style valve has a cast iron body to withstand tough environmental conditions.
• The disc on this valve is made of stainless steel to resist corrosion.

Standards and Approvals:

• NSF 372
• ANSI / ASME Class 250

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.
