High washability realized.
The external seal of the diaphragm periphery adopts a flat structure eliminating the pocket between the diaphragm and body.
There is no accumulated fluid in the pocket, so the valve stays cleaner.

High replaceability reduces cleaning time
Designed to have little dead space in which fluid may be trapped, allowing the circuit to be thoroughly cleaned.
The high liquid replaceability contributes to reduced cleaning time.
SIP and CIP are also supported.

The unique mechanism and appropriate diaphragm enable secure positioning and easy diaphragm replacement.
Retains an easily assembled and secure seal to realize a reduction in maintenance time.

Space and energy saving of equipment/facilities (air operated).
Years of pneumatic cylinder production have created a unique technology, with which we keep the actuator compact in relation to the valve bore size and reduce air consumption.

Secures maintenance space (manual).
Adopts a compact manual handle to secure sufficient space within the device, making valve operation easier.
