Page 2: High Pressure Diaphragm Valve · NRCD4C Series (Cv0.1 Compact Type) NRD4C Series (Cv0.1 Standard Type) NRHD4C Series (Cv0.25 High Flow Type) The “RD” series has been redesigned

The “NRD” series offers slim and compact high-pressure valves from small flow to high flow types.

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

Slim and compact design

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.

Ministry approved high-pressure gas products

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.

Adaptable for special specifications and block valves

A springless diaphragm structure has been adopted for all product series to reduce particles.

Adoption of springless diaphragm structure

1/4” high flow type “NRHD4”Cv 0.25 has been realized with a slim actuator and an outside diameter of φ39.7mm.

1/2” high flow type “NRHD8”A high flow type with Cv 1.0 has joined the lineup.For manual valves, reduction in handle operation torque has been realized through the adoption of a lever mechanism.
