"The versatility of the valve allows the processing of fluids in different directions, using a specifically designed casing. "

This type of tube for pinch valve is particularly adaptable for use within applications involving the control of fluids with relatively low viscosity. The valve is a high performing pinch tube type and can operate at high speeds whilst maintaining precise control. Within industries using equipment for dyeing patterns in textile materials such as carpets with liquid dye steams, the valve fulfills a specific requirement for users.

A valve block is a structured aspect of the valve which has a bore capable of receiving a flexible tube. A channel is linked transversely directed to the bore, at the intersection of which is a defined pinch chamber. Actuation of the ‘pinching’ action of the valve is by a piston rod and a free-floating ball type component, located between the rod end and the flexible tube. The pinch chamber has a wall part that is flat in form, situated in the bore opposite the linking passageway.

This linking channel is of a larger sized diameter than the bore. Provision is made for an electrically operated pneumatic valve, for a pressurized flow of gas, to actuate the piston to pinch the flexible tube into a closed state. The electrically operated pneumatic valve and piston may be installed separately, or located within a valve casing. Within the construction of the valve is an elastomer flow tube. Adding to this, are a plunger and a pinching component located adjacent to the flow tube and attached to one end of the plunger. A designated surface is located in a general position opposite the pinching component, enabling the elastomer tube for pinch valve to be ‘squeezed’ between the pinching component and the designated surface; thereby exerting control over the flow of fluid processing through the tube.

Located between the pinching component and one end of the plunger, is a guide spring. This feature is supported by a second spring of the same form, located adjacent to the other end of the plunger. If required, the connection of a damper can be associated with the plunger for certain operations, as well as a pressure-restraining component.

In applications such as medical and specialized industries, the use of disposable fluid path component is a great benefit. This applies to the potential for contamination of a processing material. A replaceable tube for pinch valve can provide for a free-flowing line of fluid, from the initial reservoir to the dispensing point. The processed fluid remains untouched until the action of dispensing occurs. This is a preventive measure against the risk of potentially contaminating particles. A specialized tube for pinch valve will provide the user with longer valve service and minimum downtime. The elastomer tube can be easily and quickly changed on-site, without the necessity of a valve ‘clean-up’.

A particular tube for pinch valve can enable the processing of aggressive or extra pure fluids by use of a silicone tube. The versatility of the valve allows the processing of fluids in different directions, using a specifically designed casing. It is possible to use other materials aside from silicone, but their suitability for an application will depend on their quality and elasticity. Determining the required power for the driving of the valve is by the diameter of the tube and its wall thickness.
