6600 Series

Pressure Regulating Valve (precision Reguler for Analytical Equipment)

MODEL 6600 SERIES

This
is a compact, lightweight precision pressure regulator with superior
repeatability to provide reliable and speedy regulations. Since all the
components are perfectly cleaned before assembly, this model is ideal
for high-sensitivity instruments for analysis required for R&D
activities.

Features

• High-precision control characteristic

High
control performance with repeatability within a range of ±1% against
fluctuations in pressure on the primary side and load resistance
variations on the secondary side

• Perfect for panel mounting

Flow
inlet and outlet are located on the back of the product to facilitate
easy pipe connection. Additionally, it is compact in size and light in
weight, ideal for panel instrumentation systems.

• Bleed-free

All units are subjected to a rigorous leak test before shipping though the product is bleed-free.

Applications

• Gas chromatographs

• Scientific instruments

• Gas mixing systems in various fields
