Description of fluid dispensing valve seriesproduct 

Standard SK-M-PEN Series products are suitable for a variety of viscous characteristics of the medium (up to 6,000.000mpas), for you to bring the pulse-free, low shear, high-precision, quantitative linear transmission of the new design concept.

Standard screw dispensing valves, adhesive pumps, filling systems and other products, widely used in the world of consumer electronics, automotive electronics, solar energy, food, daily cosmetics, chemical, steel, paint, 3D printing and other industries.


The manufacture of Standard micro-dispensing valve is based on the principle of infinite circulation piston, that is, the principle of screw. The screw valve can provide high precision volume conveying and can be reversed to make the material flow back, so there will be no drop on the discharging side. In order to adapt from low viscosity to high viscosity of a variety of media precision delivery, Standard continue to improve and innovate SK-M-PEN dispensing screw valve series.

SK-M-PEN Series of Standard brands have different Models

SK-M-PEN Series of Standard brands have different Models ( SK-M-PEN100; SK-M-PEN150; SK-M-PEN300; SK-M-PEN450; SK-M-PEN600; SK-M-PEN750; SK-M-PEN1000; SK-M-PEN1500; SK-M-PEN3000; SK-M-PEN7000 )Which can be applied to different usage, it can be integrated into the existing production line, also be used in desktop dispensing.

All the SK series was produced under the principle of screw pump with self-sealing function. The spiral structure makes the material conveying very gentle. The material transported through SK series products will be almost without any shearing force.Even if the high viscosity material SK series products can also make the high viscosity material perfect back suction through the rotor rotation .Cleaning dispensing valve and mixing point rubber valve is very convenient, material replacement can also be completed quickly.

SK-M -PEN750 Product Description

The new volume precision metering valve SK-M -PEN750 produced by Standard is mainly used in medium transmission from low to high viscosity .

Function Principle

SK-M-PEN series screw valves are designed with screw structure and pressure-proof seal. The rotor and stator are self-sealing and easy to replace. The transmission function is realized by directional rotation of the rotor in the stator cavity. The conveying process does not produce shear effect on the medium, so it does not have any effect on the properties of the medium. At the same time, it can easily realize the suction function of the media through the motor reversal, to ensure the cleanliness of the media and materials, and completely solve the problem of the media dripping and drawing.


The best volume precision quantitative transport---widely used in various dispensing, line coating, filling, sealing application occasions.

Medium viscosity chart 

The endless piston principle?

(1). The functional principle of the Standard dispenser is similar to that of an endless piston dispenser .

(2). The special conveying geometry enables continuous , pulsation - free dispensing flow . Reversing the direction of rotation ( suck - back function ) prevents dripping and leads to a controlled thread break of the material . Standard delivers high - precision and clean dispensing results .

(3). Particularly sensitive material with high viscosity and filers are treated gently due to the low shear stress and low pressures.

What kind of medium can be dosed with the SK-M-PEN series ?

(1). Light cured epoxy resin, toluene, phenol, production agent, heat curing, gasoline, high filling liquid,

(2). Shear sensitive adhesive, LED resin taste, hot conductive paste, solder paste, room temperature vulcanized rubber, silver paste, flux

(3). Industrial oils, perfumes, cosmetics and pharmaceuticals, biological suspensions, silicone, lubricants, alcohol, MEK, thermal grease,

(4). Polyurethane, solder paste, paint and ink, primer, acetone, epoxy, electrolyte solution, isopropyl alcohol and so on.

What can be the reason for too little or no flow of medium ?

(1). Potential cause: Motor (dispenser cable) is not connected
Solution: Connect motor to eco-CONTROL unit Check all connections!

(2). Potential cause: Dosing needle is blocked, dosing needle is bent
Solution: Clean and replace the dosing needle

(3). Potential cause: Medium has hardened / cured
Solution: Clean the dispenser

(4). Potential cause: The dosing needle is too small or too long
Solution: Use a different dosing needle cross-section Reduce Dosing speed / flow rate

(5). Potential cause: Insufficient supply of medium
Solution: Increase the supply pressure. Check for air-bubbles. Check the hose line.

(6). Potential cause: Stator is swollen
Solution: Check material resistance, contact manufacturer

Why is it leaking or spilling after delivery ?

(1). Potential cause: Reverse flow not properly adjusted

Solution: Adjusting the reverse flow (instructions in the Operation manual)

(2). Potential cause: Bubbles in Medium

Solution: Ventilation medium

(3). Potential cause: Medium is compressible

Solution: Medium degassing.
