Description
The Watts LF6 3/8 is a 3/8" lead-free silent spring check valve with FNPT connections. It permits flow in one direction and closes against reverse flow. It features a brass body. Rated to 235 psi and up to 180°F. This model is certified lead-free for potable-water installations.
This 3/8 inch lead free MIDI check valve is used in general industrial and plumbing applications to prevent the effects of water hammer in the piping system. It provides a silent operation with low opening pressure, low pressure drop and can be installed horizontally or vertically. This valve consists of a lead free brass body, elastomer seat, NPT female threaded end connections, positive back stop, and a unique positive check module. The maximum pressure is 200 psi (13.8 bar) and the maximum temperature is 180 degrees F (82 degrees C).
Features
- Lead free brass body
- Elastomer seat
- NPT female x female threaded connections
- Bubble tight seating
Common Questions
- Can I install it vertically?
- Yes. The LF6 3/8 is rated for horizontal or vertical lines because the spring, not gravity, closes the disc. In a vertical run the flow must be upward through the valve, following the body arrow.
- Will it slam or cause water hammer?
- No. The spring closes the disc before the flow actually reverses, so the valve seats silently instead of being slammed shut by the returning column of water. That is the point of a silent (non-slam) check.
- Does it come with a strainer?
- No. This is an inline check valve only. If the line carries debris, install a strainer upstream — grit on the seat is the usual cause of a check valve weeping by.
- Is it potable rated?
- Yes. The LF6 3/8 is certified lead-free for potable-water piping.
