MANUAL DIAPHRAGM VALVES
PNEUMATIC DIAPHRAGM VALVES
REDUCING FOR DIAPHRAGM VALVES
Diaphragm valves
In the manual SIRSI FLAV valves, closing and opening are entrusted to a maneuverable handwheel.
For pneumatic valves, the control is air controlled by entering the air cylinder. The degree of opening is indicated in an external rod, clearly visible to the operator.
The FLIR SIRSI valves, extraordinary for their versatility, are also CONVENIENT for common uses, become INDISPENSABLE when it is necessary to intercept difficult and aggressive liquids and fluids. Their safety makes them prefer to more expensive equipment.
The replacement of the diaphragm, which over time can wear out, takes place simply and quickly, without having to intervene on the flanges and without affecting the pipe.
It is available in various types of elastomers: Para rubber, Food Para, Neoprene, EPDM, MNBR, Hypalon, Viton, Silicone, Butyl, PTFE and Teflon.
The bodies are available in steel, cast iron, aluminum and with hard rubber, teflon, and ebonite coatings.

Advantages of
diaphragm valves SIRSI
-
-
Straight flow of liquids
The pressure drops in the valve are therefore minimal. Equivalent to pressure losses in a smooth pipe of equal length and diameter
-
-
Elimination of the stuffing box
and all the inconveniences deriving from it
-
-
Elimination of the gaskets on the flanges
they are effectively replaced by the sleeve itself which operates the seal with its edges, also offering a material superior to any other gasket.
-
-
Elimination of locations and plugs
and consequent elimination of repairs, spare parts, etc.
-
-
Elimination of & quot; hammering "
In the pipes, which are absorbed by the elastic sleeve.
