Diaphragm Valves – The versatile, simple & cost effective choice

Diaphragm valves have long been regarded as the best option (in many cases the only practical choice) for corrosive and abrasive applications.
However, over the years, body lining and diaphragm materials have improved to such an extent that straight through and weir type diaphragm valves
have evolved to become the most versatile, efficient and cost effective industrial valves available.

Equally suited to on/off or flow control applications, a diaphragm valve will handle positive pressures or high vacuum; linear flow characteristics
enable throttling or modulating duties  and a wide range of material options, accessories and actuation methods provide the ability to handle virtually
any application (within temperature and pressure ranges).

Diaphragm valves are typically specified for use in water treatment plants, fertilizer & petrochemicals industries, chemical industries, refineries, thermal
power stations, and other process industries. However there are many applications where diaphragm valves are entirely suitable, but not considered; due
to a perception of high price against more simple, low cost alternatives. In reality, the total cost of ownership of a diaphragm valve, in the context
of the life of the plant, is substantially lower.

All working parts of the valve are isolated from line media which dramatically increases service life. Maintenance is a simple task with the body
remaining in the pipe; reducing plant downtime to minutes instead of hours and spare parts inventory is limited to inexpensive diaphragms.
In the event that line media or operating conditions (pressure, temperature) change, a diaphragm valve can often be adapted with a simple,
inexpensive change of diaphragm material. All of these factors work together to reduce plant overheads in the long term.

Externally the diaphragm valve is very compact – allowing design engineers to improve space efficiency, provide ease of access for maintenance
and reduce construction costs in new plants. A range of compact actuators and accessories further enhance the flexibility provided by straight through
and weir type diaphragm valves.
