The pinch valve mod. Gs 22, consists of a cast iron or aluminium body (two pieces unit) and of a natural or synthetic rubber sleeve, suitable to

withstand passing fluids (acids – alkalines powders – cement – waste and industrial water – sludge).

Closing occurs by pressing of a compressed air operated cylinder acting on a pad which in turn squashes to full closure.

Valve’s peculiarity is lack of stuffing box and load loss.

LS microswitches can be applied to indicate valve’s position (open or closed) as opposed to other types of valves where direct input of air on sleeve does not allow it.

Rubber sleeve one-piece moulded, comprises due terminal flanges acting as coupling gasket.

The pinch valve mod. GS 21, consists of a cast iron or aluminium body (two pieces) and of a natural or synthetic rubber sleeve, resistant to fluid flow (acids – alkaline fluids – dusts – concrete – sewage and industrial waters – muds).
Closing is performed by pressing a screw on a buffer, which squeezes sleeve to a complete or partial closing.
This valve is special since no stuffing box and load loss appear.
One-piece printed rubber sleeve includes two terminal flanges used as coupling gaskets.

These valves are used for the same purposes as valves with closing control, however their design departs from the latter because the valve is fitted with a double action hydro-pneumatic cylinder for the opening and closing operations.
The valves of this model are available in the flow diameters ranging from 100 to 350 mm.

The model G.S.8 pinch valves (normally closed) have an automatic, double, spring closing device and correspondingly double apparatus for hand and hydropneumatic remote opening; this latter is done by simultaneous and balanced action of the pressure in the two cylinders.

By means of the device closing and opening is made easier and regulation of flow more accurate. Diameters of the G.S.8 go from 80 to 200.

Often a valve is required which under normal conditions is closed and perfectly tigh but, if necessary, it could be opened remote control: pinch valve G.S.7 meets these requirements since it features the automatic spring closing system and double control (handwheel and hydropneumatic cylinder) for the opening system.

These valves feature a double pressure cylinder for the remote controlled, either pneumatically or hydraulically, closing operation; they do not feature any hand control. The opening operation is automatically controlled by suitable springs housed in the pressure cylinders; all operations are simultaneous and symmetrical to the centreline of the sleeve; in this instance, therefore, no flexible coupling for teh remote control line is required.

This valve is used for large flow diameters and has all moving parts enclosed in a suitable case.

Valve model G.S.5 consists of a two section steel body housing the flexible coupling; the two claws of the clamp, one driven by the handwheel screw and the other by the piston of the pressure cylinder, slide in the body.

The stiff frame consisting of two stainless steel tie-rods and two bronze cross-members, is secured to the cylinder by a fixing member, the spindle of the control handwheel is screwed to the other member.

This is a pinch valve with double hand control, specially recommended for the biggest flow diameters. The double control ensures easier regulation of delivery; further, the drive parts are entirely enclosed in a casing. Valve sizes start from an N.D. of 250 mm.

The G.S.1 model pinch valve is fitted with parts for closure by hand at balanced pressure, enabling closure to be made with only very slight deformation of the hose coupling, but allowing it to become perfectly cylindrical when the valve is fully open.?

The hose coupling (moulded in a single piece) has two end flanges which, without any extra packing, ensure a perfect seal between the valve packing and the pipe or receptacle to which the valve is fitted.

PROCHEM klämventiler är förmodligen den enklaste formen av on / off eller flödesventiler finns. De är lämpliga för hantering av ett brett spektrum av fasta ämnen, slam och vätskor.
Ventilerna är av mycket enkel konstruktion med endast två huvudkomponenter – en flexibel elastomerhylsa innesluten i en ringformig kropp hölje. Slit antalet komponenter begränsas till bara en punkt – den enkelt bytas ärm. Nypa ventiler är mycket mångsidig och kan användas för flera olika uppgifter – på / av, flödeskontroll, tryckavlastning, eller tryckbelastning. När komprimerad luft, vatten eller annan tryckfluid införes i det ringformiga höljet hylsan sluter tillhandahålla förutsägbar stängning och en stor tätningsarea för dropp tät avstängning – även med uppfångade fasta ämnen.
