Pinch Valves

The manual or pneumatic pinch valve has a straight flow without gland.

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.

Advantages of
SIRSI pinch valves

  • 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.
