PEEK valve block

At Kriloha Ltd., we recognize that the valve block is the central nervous system of any advanced fluidic architecture. Our PEEK Valve Blocks represent our engineered answer for “Fluidic-Path-Optimization” and “Structural-Isolation-Integrity.” As a premier provider of customized polymer solutions, Kriloha has developed a specialized 5-axis CNC fabrication division dedicated to translating your most complex internal channel designs into field-ready reality.

The engineering of our valve block program is founded on Internal-Geometry-Precision and Surface-Smoothness. Unlike standard molded blocks, our CNC process allows for the creation of intersecting cross-drilled channels, tapered ports, and integrated sensor seats with sub-millimeter accuracy. At Kriloha, we verify the internal bore finish of every bespoke block to ensure a low surface roughness (Ra), which is essential for maintaining laminar flow and preventing the accumulation of biological or chemical residues.

Manufacturing these advanced polymer manifolds involves strict Pressure-Testing, Thermal-Calibration, and Purity Verification. We collaborate directly with your fluidics engineering teams to process bespoke configurations—including proprietary thread standards, integrated sealing ring grooves, and specialized mounting interfaces. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s fluidic efficiency through superior material performance.

Primary Use Cases

Analytical & HPLC Manifolds: Central distribution blocks for liquid chromatography systems that require precise routing of multiple mobile phases.
Medical Diagnostic Hardware: Core fluidic blocks for automated blood analyzers and diagnostic equipment that must remain biocompatible and autoclave-safe.
Semiconductor Chemical Delivery: Customized manifolds for the distribution of etching and cleaning chemicals where metallic ion leaching must be zero.
Biotechnology Bioreactors: Specialized gas and liquid distribution blocks that require frequent high-heat sterilization and chemical resistance.
Aerospace & Satellite Fluidics: Lightweight, high-strength manifolds designed to manage pressurized air or fuel in compact, mission-critical assemblies.

Frequently Asked Questions

Can Kriloha machine internal “T” or “Y” junctions with zero dead volume?

Yes. Our precision CNC technology allows us to machine intersecting internal flow paths with exact alignment, ensuring there are no pockets where fluid can be trapped, which is vital for high-purity analytical applications.

Why use a PEEK valve block instead of Stainless Steel?

Stainless steel is heavy, prone to corrosion in acidic environments, and can leach metallic ions into the fluid stream. PEEK offers the chemical resistance of an inert polymer with the structural strength required to handle industrial pressures.

Is PEEK suitable for vacuum-based semiconductor processes?

Absolutely. PEEK has exceptionally low outgassing properties and high thermal stability, making it the industry standard for vacuum manifolds where particulate and gas contamination must be minimized.

Can the valve block be sterilized in an autoclave?

Yes. PEEK is highly resistant to hydrolysis. Our valve blocks maintain their dimensional accuracy and thread strength through thousands of high-pressure steam sterilization cycles.

What thread types can be machined into the block?

We can machine any thread standard directly into the PEEK body, including NPT, Metric, or specialized flat-bottom ports (like 1/4-28), ensuring a leak-proof mechanical fit with your existing fittings.
