High-Pressure Impingement Mixing Valve: Revolutionizing Polyurethane Processing
How it Works:
The High-Pressure Impingement Mixing Valve operates with meticulous precision, ensuring the seamless blending of materials in both filled and unfilled polyurethane applications. During the dispensing cycle, our valve utilizes a recirculation mode, where materials flow through control orifices and recirculation grooves on each side of a precision plunger. This innovative design allows for optimal mixing efficiency before the materials impinge at pressures of up to 3,500 psi, resulting in a smooth and consistent pour into open and closed molds, enhancing the overall quality of your end products.

High-Pressure Foam Mix Heads for Reliable, Cost-Effective Polyurethane Processing:
KIRKCO L-style and straight polyurethane foam mixing heads are designed for high-pressure impingement mixing, offering long life across a wide range of open mold and closed mold applications.
Mixing Head Variants
Straight Type Mixing Head:
During a recirculation mode, materials flow through control orifices and recirculation grooves on each side of a precision plunger before returning to the machine tanks. When a dispense cycle is initiated, the plunger, actuated by a double-acting cylinder, retracts, allowing both materials to impinge at pressures up to 3,500 psi (ideal for closed mold applications).
Straight-Style Mix Head Features:
- Ideal for continuous and discontinuous panel applications.
- Compact
- Economical
Injector Styles:
Conical Style injectors for rigid and flexible foam applications, including refrigerators, walk-in coolers, furniture, and automotive seat cushions. Choose from a wide range of orifice and needle sizes for optimal mixing and shot control.
Diesel Style injectors for hard-to-mix polyurethane foam applications like steering wheels and acoustical foams. Select from various sizes and spring-adjustment or pin-adjusted holders.
Pneumatically controlled injectors are available for setpoint control or remote adjustment of shot pressures. Let our process experts help you select the correct model and combination of injectors for your application.
