Features
Slim and compact design
By adopting a new type high-output actuator and an internal thread
body structure, a simple and compact design has been pursued.

Lineup of high ﬂow types

Adoption of springless diaphragm structure

OptionNRMD8Pneumatic valve

Ministry approved high-pressure gas products
The NRD series high pressure diaphragm valves are also compatible with ministry approved high-pressure gas. (N-valves,
N-II ﬁttings, M-pipes, and Z-complex devices)
When placing an order, a detailed statement of high pressure gas ministry approved items is required.Contact our sales staﬀ
for details.

Adaptable for special speciﬁcations and block valves
These are adaptable for special ﬂow passages, face-to-face dimensions for ﬁttings other than standard products, multiblock
valves, etc.
Contact our sales staﬀ for details.

Precautions① The valves are designed to be used under atmospheric pressure. Usage such as under vacuum vessels are not guaranteed.
② For high temperature applications, please select appropriate material for air-ﬁttings and tubes to assure proper performance.
