Sodium Hypochlorite Ball Valves

Applications involving sodium hypochlorite pose specific problems due to its unstable nature and tendency to create crystalline salt deposits which accelerate wear for standard ball valves.

 

In addition to crystalline growth that cuts-up standard ball valve seats and seals, the reactivity in industrial and municipal waste water treatment often results in generation toxic off-gas.  If this gas is captured within the ball cavity, it can stress the stem seal and cause leakage.

 

Hayward^® created the Z-BALL true union ball valve to safely vent any gases while keeping the inner valve surfaces wetted, which is critical for reducing build-up of crystalline salts.

 

The Z-BALL is easily recognized by it's black T style handle and special labeling which also identifies the direction of flow.  The vent hole is always oriented towards the valve discharge (outlet).

 

Like most Hayward^® ball valves, the Z-BALL has a true union design, enabling maintenance or replacement without breaking-down the pipeline.

 

Not All Ball Valves Are Alike

Hayward^® true union ball valves have a finely threaded seal retainer to enable adjustment to compensate for seat wear.  In addition to this functional life extending feature, the PTFE seats are reversible to ensure a damaged or worn valve can be quickly returned to service.  These valves also have a double o-ring stem seal to protect against leakage.

 

Actuate Your Z-BALL Valve

Hayward^® true union ball valves are designed to be automated with either electric or pneumatic actuators using a mounting bracket that doesn't need to be glued or clamped-on.  The special mounting bracket ensures positive shaft alignment and it is easy to transform valves from manual to automatic or back to manual operation.

 

You can “convert” an existing Hayward^® true union ball valve to be actuated OR you can order them that way.

 

Custom configured valve actuators can be specified and attached to actuator ready ball valves.  This is a two-step process; first you select the actuator ready version of the ball valve (without manual handle) and second you select the corresponding actuator, using the navigation menu above.  It is probably easier for you to simply complete our inquiry form and let us look-up the proper valve and actuator combination than it is to do the research yourself.
