Valves
Continuous valve
The valve is equipped with a fast filling housing in which gas orifice (VPH) and product orifice (RTP) can be of various dimensions. The dip tube is mounted outside the housing tang.
NRKRA valves are generally employed for water-based products filled with liquid gas (LPG) or for highly inflammable products. In this case the orifice dimensions selected according to the gaseous or liquid phase, guarantee a perfect atomization of particles, thus producing a very fine and uniform spray that reduces the inflammable properties of the product.

FILLING METHODS AND FILLING SPEED GRAPH
For these valves the mechanical opening of the stem is necessary.
(*): Suggested dimension that must assure mechanical opening 1.5 ± 0.3.
The filling speed graph refers to butane-propane propellant.
It is purely indicative, as it is based on historical data.
The filling speed depends on the injection pressure, on the characteristics of the filling machine and on the dimensions of the valve’s components (shape of the stem, number and diameter of the orifices on the stem and on the housing).
Given the high number of parameters that can cause significant variations in the quoted values, if specific information is required please ask Coster commercial offices to obtain precise data on a specific model.
Topical
RxPack's product offering includes multiple valves for topical applications, from continuous to metering, upright or inverted positions, and 360° use. The range is completed by a comprehensive actuator portfolio enabling to dispense of liquids, powder-based formulations, foams, and highly viscous products. Specific features apply when used in combination with compressed gasses, HFA, or butane-propane blends.
