Manually Operated 2/2 Way Diaphragm Valve

3232 DN15-50 mm

• For aggressive media
• Flow optimised body
• Tough, durable PPS handwheel
• Self-emptying
• Low dead volume

Hand operated diaphragm valve for aggressive chemicals. Provides long Envelope Dimensions [mm] (see datasheet for details)
service life even with polluted, dirty or high viscosity fluids. The diaphragm
between the actuator and body hermetically isolates the fluid from the
actuator and provides a strong seal over the valve seat. The manual nature
of the operator means that the valve can be used for shut-off and for flow
control.
