This type of valve is actuated by pressure acting on a professional piston or diaphragm. The fluid is usually neutral e.g. air, water, hydraulic professional oil. The pressure range varies and is specified accordingly in a data table.
"Normally Closed" (N/C) cocks of this type remain closed under professional 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 industrial actuator or remotely.
In some professional 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 suppliers 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 Cocks. 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. |

Pneumatically actuated diaphragm valves suppliers of the future
The DIASTAR product series from GF Professional piping Systems presents a complete family of pneumatically actuated industrial diaphragm cocks providing you with an optimal solution for controlling aggressive media.
Valve bodies are available with threaded connections, spigots, sockets, flanges and branches, depending on the installation. International
standards, e.g. ISO, BS, ASTM, ANSI and JIS, have also been taken into consideration.

Professional 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 Manufacturer of 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 Cocks 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.

Rotary Diaphragm cylinders
Product Description
Design Features: DeZURIK diaphragm actuators are designed specifically for use on quarter-turn cocks. They feature all steel, cast iron and stainless steel construction for corrosion resistance in caustic environments. The actuators are designed for on-off or modulating service in either a fail-open or fail-closed mode. Action can be easily changed in the field with no additional parts required. The spring cartridge is caged at the factory for increased safety. The output shaft is supported at the top and bottom with bronze bearings specifications that absorb side thrust and insure smooth, efficient, and accurate throttling control.
