A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows water to flow through it in only one direction.  Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.

The check valve is suitable for horizontal or vertical installation.

The disc is constructed of high-strength bronze with a rubber seal recessed into the disc to assure a positive seal, even under low pressure.

Valves are available with lever and spring or lever and weight for applications where rapid flow reversals may be encountered.

Piping should be properly supported to avoid stress on the valve.

Piping should be properly aligned and spaced so the bolting of the valve in the line is not used to correct any errors in piping alignment or spacing.

Install the valve with direction of flow arrows pointing in the direction the water will be flowing.  Water flow must be horizontal or vertically upward through valve waterway.

To reduce check valve slamming, the valves are supplied with the optional outside shaft configuration may be equipped
with either a lever and weight or a lever and spring option.  The principle behind these options is to close the check
valve before the fluid establishes a reverse flow.  The amount of closing torque required will vary with each water or wastewater system and can be adjusted by changing the number and position of the weights or springs.
