High-Purity Single-Stage High-Pressure Point of Use

High-Purity Single-Stage High-Pressure Point of UseIntroduction

The Druva high-purity high-pressure point of use is engineered for demanding environments, combining cutting-edge technology and precision control. Featuring a stainless steel diaphragm, pre-shut-off valve, pressure reducer, and back pressure gauge, this single-stage outlet point ensures reliable gas management in high-pressure applications. The diaphragm shut-off valve with 90° function guarantees reliable shut-off at the point of use. Perfect for laboratory and automobile manufacturing operations, this high-purity gas outlet offers unparalleled performance.

Includes pre-shut-off valve, pressure reducer, back pressure gauge, mounting plate; optional check valve and/or relief valve.
Four-port pressure regulator features a durable stainless steel diaphragm for precise control.
Diaphragm shut-off valve with 90° closing function at the point-of-use inlet for reliable shut-off.
Compact design makes it space-saving and easy to install in tight spaces.
Accurate pressure adjustment ensures precise and stable pressure control for optimal performance.
Safety pressure gauge (conforms to EN 837-1 standards) in the downstream pressure area for safety monitoring.
Electrostatic charge-free makes it safe for use in EX Zones 1 and 2.
