Kofloc Pressure Regulating Valve Model 6600 Series

Kofloc 6600 Series Pressure Regulating Valve 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 the analysis required for R&D activities.

Kofloc 6600 Series 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.
