High Pressure Color Stack

Simple in design and flexible in configuration!

1. Robust Manifold Design

Durable, precision-machined manifold blocks offer high

quality performance.

2. Low and High Pressure Valves

Versatile designs meet a broad range of applications.

3. Large Fluid Porting

1/4 inch fluid ports provide less restriction and pressure

drop. Dual fluid ports allow circulation capability.

4. Interchangeable Needles and Seats

Multiple configurations meet the needs of specific

material and application requirements.

5. Actuation Indicator

Signals valve actuation.

6. Cartridge Style Valve

Disconnects quickly without removing fluid lines for easier

serviceability and less maintenance time.
