MANUAL PINCH VALVES
PNEUMATIC PINCH VALVES
MOTORIZED PINCH VALVES
It consists of a flexible and elastic sleeve, resistant to corrosion and abrasion, integral with the mechanical part not subject to permanent deformations.
The sleeve performs a very high number of openings and closures in a short time.
It is suitably chosen according to the various uses and is available in various types of elastomers: Para rubber, Food Para, Neoprene, EPDM, MNBR, Hypalon, Viton, Buna, Butyl, Silicone.
The closing mechanism is completely protected from any contamination of corrosive liquids and ambient fumes.

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 "hammering"
In the pipes, which are absorbed by the elastic sleeve.
How to order SIRSI Valves
1. The nature of liquid or gas
2. The concentration expressed as a percentage, in grams per litre o in Baumé degrees.
3. The minimum and maximum working temperatures.
4. The maximum working pressure.
5. The type of flanges desired
SIRSI Metallisator ‘s technical staff will choose the best sleeve or membrane for any type of valve for your application.
