2/2 Way Pneumatically Operated Diaphragm Valve with Stainless Steel Body, DN 4-100
|
|
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.
|
|
|
|
|
|
Remote Control Valve:
Hayward's Pneumatically Actuated Diaphragm Valves are designed for the reliable, remote control of liquids in piping systems. They are suitable for both clean and slurry type fluids at pressures up to 150 PSI.
Position Indicator:
You never have to guess if a Hayward Diaphragm Valve is in the open or closed position. A visual position indicator comes standard with every valve.
Powerful Actuator:
The actuator used to operate the valve, while lightweight and compact, is still powerful enough to open and close the valve at all internal pressures up to the full rated pressure of the valve,150 PSI.
No Corrosion Problems:
Hayward's Diaphragm Valves stand up to the most aggressive fluids and they will never rust, corrode or contaminate the process fluid. Even the actuator housing is plastic and requires no failure prone coating or painting.
Modular Options:
Several modular design options are available. This concept is very cost effective because the actuator can be configured exactly for a specific application using only the options required. You never have to pay for options you do not need.

Robust construction
Designed for continuous operation, suitable for various duties. Simple installation and commissioning.
Hysteresis-free and excellent regulation characteristics:
are prerequisites for regulating tasks. This is achieved by the continuously variable aperture from 0 – 100%, similar to the IRIS diaphragm of a camera, always maintaining a central flow and by an enhanced segment edge design.
Non-clogging due to the free, central flow design and the automatic, self-cleaning feature of the segment edges during valve operation. Flushing connections are provided.
Examples of applications:
Air, sugar, suspensions, sewage, sludge, paper stock, drinking water, etc.
Energy cost savings and low noise emission through enhanced design. Fixed throttling apertures and imprecise regulating methods cause unnecessary pressure losses and energy costs. Due to the almost free passage and low turbulences in our valve these are reduced to a minimum. Because of an advantageous basic characteristic, we can operate in an energy saving manner, i.e. with optimal valve apertures.
