The Seaways Proportional Valve precisely blends virgin and lower-grade or recycled material in controlled proportions before feeding it to the next stage of processing. Built from durable stainless steel with a dead-corner-free internal design, it prevents material buildup and keeps raw material flowing clean and uncontaminated. A microcomputer manages the mixing ratio for accurate, repeatable dosing – a cost-effective way to cut material costs without compromising output quality.

Why Choose Seaways

Proportional Valve Features

Built to industrial dosing standards for precise, repeatable blending of virgin and recycled material in continuous-running production lines.

Precise Proportional Dosing

Accurately meters virgin and lower-grade material in set proportions for consistent, repeatable blend quality.

Microcomputer Ratio Control

An onboard microcomputer manages the mixing ratio, ensuring precise measurement and optimal performance.

Dead-Corner-Free Design

A carefully engineered internal geometry eliminates dead corners, preventing material buildup and contamination.

Durable Stainless-Steel Body

Constructed from stainless steel for corrosion resistance, hygiene, and a long service life under continuous use.

Low-Maintenance Operation

The clean internal design minimises residue, reducing cleaning frequency and downtime between material changes.

Smooth Material Transfer

Ensures uncontaminated, free-flowing transport of raw material to the next stage of processing.
