Check Valves/Relief Valves
photo
Check valve allows fluids to flow only in forward direction but not in backward direction. This valve prevents flowing in backward direction at the mixing point and enables to apply the back pressure to the fluids flowing the tube.
Relief valve is the safety valve to adjust opening pressure at will.

Check Valves
Model CK
photoSpecifications
Features
The valve is opened on low pressure (Approx.10kPa) from front direction.
It can be used for various types of chemical fluids such as organic solvents, as well as strong alkaline or acid fluids,since the part in contact with fluids is made of excellent anti-corrosive fluorine resin (PFA, PTFE).
You can mount this products on any directions due to special spring used.
Compact design and easy connection.
