K20 Series High-Pressure 2K Dispensing Valve

Product Code: K20DSX

High-precision 2K dispensing valve with independent A/B flow control and stable performance under up to 20 MPa. Ideal for accurate adhesive and sealant mixing in automated applications.

Precise Dual-Flow Control

Each A and B channel can be finely adjusted to ensure accurate ratio control—even with large viscosity or density differences between components.

Air-Actuated Needle Design

Double-acting air operation provides fast response and stable open/close movement, minimizing material surge and ensuring consistent bead profiles.

Corrosion-Resistant Structure

All-stainless-steel construction handles pressures up to 20 MPa (5 MPa for HV model) and provides superior resistance to corrosion and wear.

Easy Maintenance

Dual-life reversible seat design and available seal kits (103301 / 103501) simplify maintenance and extend lifetime.

Compatible with Various Mixers & Systems

Directly connects to static mixers and integrates seamlessly with high-pressure pumps, metering, and control systems for diverse 2K dispensing setups.

2K adhesive & sealant dispensing for resins and hardeners with different viscosities or mix ratios.
Used in automated production lines requiring accurate ratio control and stable flow.
Dispensing 2K adhesives for lens bonding, housing sealing, and waterproof encapsulation.
Mixing and dispensing resin and hardener for cell-to-cell bonding, battery cover sealing, and thermal gap-filling in EV modules.
Bonding and potting connectors, switches, and sensors using two-component polyurethane adhesives.
Sealing oil pans, starter motors, and water pumps with heat-resistant 2K sealants.
Applying precise 2K silicone beads around cable glands and plug housings.
Precise metering of lubricants, epoxy coatings, or thermally conductive compounds.
