Pressure Regulating Valve
MODEL 6600 SERIES
It is the light-weight and compact precise-pressure control valve having superior reproducibility. It enables sure and rapid pressure control with high accuracy. Since the inside of the valve has been rinsed completely with the super-cleaning method, it should be optimum product as a high-sensitivity analysis device or for research and development.

Features
Control characteristics with high accuracy
It provides high control performance of reproducibility 1% for primary pressure fluctuation and secondary load resistance fluctuation.
Optimum for panel installation
Since the inlet and outlet for liquid are installed at the back of the body, pipes can be easily laid. And it is optimum for panel installation because of its light-weight and compact size.
Non-bleed type
It is a non-bleed type and has passed strict leakage tests.
Pressure Regulating Valve
Application
For gas chromatograph
For chemical measurement instruments
