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

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

For critical applications requiring flawless gas management, the Druva high-purity absolute-pressure point of use delivers unparalleled accuracy and reliability. This single-stage gas outlet features a durable stainless steel diaphragm, a pressure reducer, and an optional check valve for consistent performance. The diaphragm shut-off valve with a 90° closing function provides secure shut-off at the inlet, ensuring precision under absolute pressure conditions. Its compact design and easy installation make it a perfect choice for laboratories and high-precision manufacturing.

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.
