When should I use the 2695 Separations Module check valve (WAT270941)? - WKB238819

ENVIRONMENT

• 2695 Separations Module

ANSWER

The internal ball of the WAT270941 check valve is made of the same ruby as the standard, but the size of the ball is smaller than the standard.
The bigger the ball, the less likely it is to clog.
The small ball type is useful for low flow rate measurements.
By reducing the stroke (the length of the plunger's movement) when the flow rate is low,
The pressure change point at top dead center and bottom dead center of the plunger (moving rod inside the pump head to pump liquid) becomes small.
Smaller balls are more responsive to this.
