Miniature Proportional Valve

Product catalog summary

Miniature Proportional Valve KLPV-MN - Overview

The KLPV-MN is a miniature proportional valve featuring a unique non-spool design with a single moving part. This design ensures virtually frictionless operation and an exceptionally long lifespan, tested to exceed 100 million cycles. The valve is engineered for ease of maintenance and cleaning due to its simple construction. It is suitable for various media including water, air, oil, hydrogen, and oxygen, and performs reliably across a wide temperature range.

Performance Characteristics

The valve demonstrates typical flow characteristics at 20 VDC rated voltage and 10 PSIG inlet pressure, providing precise proportional control of flow rates within specified ranges.

Dimensions and Mounting Options

The valve is available in two mounting configurations:

Manifold Mount Version: Compact design suitable for integration into single-station manifolds.
Inline Mount Version: Base mount with M5*0.8 port threading for inline installation.

Detailed dimensional drawings are provided for both versions to assist with system integration.

Ordering Information

The product is identified by the model code KLPV-MN, with options available for orifice size, seal material, port type, and control voltage to tailor the valve to specific application requirements.

Critical Notes and Best Practices

The valve’s non-spool design minimizes friction and wear, significantly extending operational life.
Selection of seal and wetted materials should consider the specific fluid media and temperature conditions.
Proper filtration (40 micron recommended) is essential to maintain valve performance and longevity.
Operating within specified pressure and temperature ranges ensures consistent performance.
Electrical control voltage must match the selected valve configuration for optimal proportional control.
