Technodigm offers dispensing valves from simple manual pinch tube designs to precision rotary auger valves. Our comprehensive range ensures excellent accuracy over a range of material viscosities and shot sizes. Technodigm dispensing valves provide ON-OFF functions, and metering in the proper ratio of A and B components is controlled by the metering pumps. Different manifolds are offered to assist this metering process. The selection of the manifold for each application depends on the flow rate, viscosity, and volume ratio. Advantage of dispensing valves: Eliminate solvent flushing Less adhesive waste Cleans up easily Increased productivity

1. Dispensing valves
Diaphragm Valve
Diaphragm Valve is designed for low to medium viscosity material such as light-curable
adhesives, anaerobic adhesives, cyanoacrylates, epoxies, fluxes, inks, paints, and solvents.
In this design, fluids do not contact the actuating components within the dispensing valve,
making it ideal for dispensing reactive materials such as cyanoacrylates and solvent-
based products.

Snuff Back Valve
SBV100 is a snuff back valve. The action of this valve is such that on the retraction of the piston, a “negative pressure”
is created to “pull back” the material so as to achieve a quick cut off and or prevent dripping of material. This valve is
suitable for a wide range of material but is especially good for grease, silicone and pasty materials. Easy to maintain
and operate, this valve is economical and robust.

3. Positive Displacement Valve
PDV 100 can be used as a positive displacement valve for dotting processes. It is designed such that with an appropriate
combination of fluid pressure and fast closing time, a consistence amount of material can be achieved repeatedly.
However if line dispensing is what is needed, this valve can also be used. Wetted chamber are of stainless steel with
Teflon seals.
