Kofloc Precision Flow Meter for Pressure Regulator Model RK4400 Series

Precision Flow Meter for Pressure
Regulator (for Cylinder Regulator)
MODEL RK4400 SERIES

The KOFLOC RK4400
has been designed specially for connection
to precision pressure regulators, and is widely
used for cylinder
regulators.
Features
-The precision needle
valve Model 2412 is used for easy, fine adjustment of flow.

– The flow meter tube made by high-precision
molding ensures excellent stability and repeatability even if it is inclined.
– The material, cleaning method, and assembly
are carefully designed for the use of high-purity, high-price standard gases so
as to eliminate waste losses, reduce absorption of constituent gas and minimize
generation of other types of gas from the parts.
– For cylinder regulators
– For line regulators

Purchasing
• Almost all types of general cylinder regulators can be
attached.Refer to Model 7700 for a product equipped with a cylinderregulator.








• Our company will select a needle valve. Be
sure to clearly indicate the supply pressure (preset pressure of cylinder
regulator).
