Description

Miniature Precision Air Pressure Regulator – Shako NR200 Series


Compact Diaphragm Pressure Regulator for Precise Pneumatic Pressure Control

The Shako NR200 Series Miniature Air Pressure Regulator is a compact diaphragm-operated pressure regulator designed to provide accurate and stable pressure control for compressed air systems where space is limited and precise regulation is essential.

Available with 1/8" or 1/4" BSP ports, the NR200 Series is ideal for laboratory equipment, instrumentation, compact automation machinery, pneumatic control panels and miniature air circuits requiring consistent downstream pressure.

The diaphragm regulator design provides smooth, accurate pressure adjustment with excellent regulation sensitivity, while the relieving function automatically vents excess downstream pressure when the regulator setting is reduced.

Diaphragm Pressure Regulation

Unlike piston regulators, the NR200 uses a diaphragm-operated regulating mechanism, allowing more accurate pressure adjustment with improved sensitivity and stable downstream pressure control.

The relieving regulator design automatically releases excess downstream pressure when the pressure setting is reduced, eliminating the need to manually vent the system before readjustment.

Pressure Ranges

NR200 (Blue): 0.5 to 8 Bar
NR200L4 (Orange): 0.05 to 4 Bar
NR200L2 (Yellow): 0.05 to 2 Bar
