advantages of diaphragm valves
Manual diaphragm Valves are ideal for flow control by offering a variable and
precise opening for controlling pressure drop through the valve. Actuated
varieties can offer features as adjustable opening, positioners for precise flow
control, and electric relay of Valve position.
There are many advantages
of diaphragm valves. They are extremely clean, and can form a nearly leak-proof
seal for tight shut-off. The diaphragm design provides for easy maintenance and
repair as it can be replaced without disturbing the piping line. How every, they
are limited to moderate temperature (-60Cto450C degree) and pressure service(
approximately 300 psi) by the mechanical properties of most common diaphragm
materials. They cannot be used in multi-turn operations.
Diaphragm Valves are available in two basic forms: weir type and straight through types.
The
weir design is best for general use applications or for tough corrosive and
abrasive services. The straight through type can be used in situations where the
flow direction changes within the system. Thy can excellent for use with sludge,
slurries and other viscous fluids, Both styles provide a streamlined path for
fluid flow that yields minimal pressure drop across the valve.
The flow
transfer and control category covers a wide spectrum of products designed to
facilitate, control, maintain, meter, or read the flow of material through
hoses, pipes or tubing. The material in question can be liquid, gaseous, or
semi-solid (colloids and slurries). The following families fall within this
category: valves, valve actuators and positioners, dispensing valves, pumps,
flow sensing, lever sensing, density and specific gravity sending, viscosity
sensing, and miscellaneous related products.
