Gas pressure relief valve RSP

airBSPTlow-pressure

Features

• Designed for use from atmospheric pressure down to low (micro) pressure ranges
• Stable repeatability of sealing performance thanks to a special diaphragm structure
• Ideal for pressure control in micro-pressure environment equipment and pneumatic circuits
