Hunter HPV Series Valve

Description:

The is a 1" size residential valve made for use in dirty water situations.

Features:

• Heavy duty solenoid.
• Captive solenoid plunger and body parts (means they don't fall out into the dirt if you take the valve apart. You have to have dropped a solenoid plunger into a valve box full of muddy water, spiders, ants, and toads to really appreciate this feature!)
• Internal manual bleed (the valve does not squirt water when manually opened)
• Optional flow control (I strongly recommend this option)
• Self-flushing filtering system (reduces damage to the valve caused by small amounts of sand in the water.)
• Rigid diaphragm support (this means the diaphragm seats firmly against the top of the valve chamber when open. The idea is that this reduces the stress on the diaphragm caused by the water pressure.)
• Available as either a globe or angle pattern valve. (Globe means in one side, out the opposite. Angle means in through bottom, out through side.)
• The globe style is available with slip inlet and outlet (glues onto PVC pipe.)

Review:

The HPV is a dirty water valve. That doesn't mean the valve cleans the water. What it means is that this valve has a self-cleaning screen inside it that protects the valve from dirt in the water. Let's quickly clarify that dirt means small amounts of sand. If the water looks dirty, it is probably too dirty. If the water is visibly dirty I would recommend that you filter the water before it reaches the valves.

The HPV have black PVC plastic bodies, they have some UV light resistance but I strongly suggest you install them in a box or protect them from sunlight. The flow control is an option, I strongly recommend it. Without the flow control you will not be able to close the valve manually if it sticks open, nor will you be able to fine tune the valve closing speed.
