Milwaukee 8814-1400 silent check valve is designed to eliminate water hammer and shocks which may be created by sudden stoppage of a reverse flow. It is used for mining, processing, power, oil & gas, pharmaceutical and food & beverage applications.
Features:
- Milwaukee 1400 check valve features cast iron construction for superior compressive strength, rigidity and durability.
- It features a seat and a disc that controls the water flow of the pump and prevents reverse flow automatically.
- It has a wafer body design that creates a positive seal to prevent bi-directional pressure differential in the flow of fluid and avoids backflow in systems that are only meant for uni-directional flow.
Standards and Approvals:
- NSF / ANSI 372-2016
- MSS SP-125
Frequently Asked Questions:
Q. In what direction can the silent check valve be mounted?
A. Milwaukee 1400 check valve can be installed in both horizontal & vertical positions, with the flow going upwards. The flow arrow must always point in the direction of flow when the system is in operation.
Q. What is the seat made of?
A. The seat is made from stainless steel to provide a high level of corrosion resistance and can be used in mining, pulp & paper, and chemical applications.
Q. What is the purpose of the spring in Milwaukee check valves?
A. When the pump shuts off, the stainless steel coil spring forces the disc to close against the pump head at zero velocity, resulting in silent closure.
