Kofloc RK4400 Precision Flow Meter for Pressure Regulator has been designed especially for connection to precision pressure regulators and is widely used for cylinder regulators.
Kofloc RK4400 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 the absorption of constituent gas and minimize the generation of other types of gas from the parts.
- For cylinder regulators
- For line regulators
