This type of valve is actuated by pressure acting on a piston or diaphragm. The fluid is usually neutral e.g. air, water, hydraulic oil. The pressure range varies and is specified accordingly in a data table.
"Normally Closed" (N/C) valves of this type remain closed under spring pressure, when de-activated.
"Normally Open" (N/O) valves of this type remain open under spring pressure, when de-activated.
When pressure is connected to port "Z" the valves open or close according to type.
A separate 3/2 pilot valve is used to supply pressure to port "Z", it is mounted either directly on the actuator or remotely.
In some cases a 4/2 or 5/2 pilot valve will be required. The main valve position can be N/C or N/O. The basic position is determined by connecting the pilot valve output lines accordingly. (The direction of flow is usually indicated by an arrow or shown schematically on the body). |

Superior Design:
Hayward all-plastic diaphragm valves have been specifically designed to perform in the most demanding liquid, gas, and slurry applications in both on/off and modulating service.
Position Indicator:
Hayward's standard highly visible, beacon-type position indicator will always give positive position indication, unlike rising stem indicators that can be inaccurate because of misadjusted stems. Sight panels are made from clear Eastar®.
Diaphragm Saver:
The Diaphragm Saver travel stop is a standard feature on all sizes of Hayward Diaphragm Valves. Its special design prevents overcompression of the diaphragm and prolongs its service life.
No Corrosion Problems:
These valves have no wetted metal components. The valves will never fail because of corrosion and they do not require painting or epoxy coating to stand up to aggressive environments.
True Union Design:
Hayward Diaphragm Valves with socket or threaded connections have a true union design so that they can be removed from the line without having to disconnect piping connections. |
