KDR.FL mO | Flange-mounted pressure regulator

Compact membrane pressure regulator with secondary venting and control cartridge for flange mounting. This precision pressure regulator is suited for all applications that demand high control precision, such as in ventilators and anaesthesia devices.

We use special materials allowing it to be used in the most sensitive equipment. Depending on the requirement, this enables the achievement of results such as oil, lubricant, silicon or phthalate-free (biocompatible) for example.

DR.036 mO | Cartridge pressure regulator

Compact membrane pressure regulator with control cartridge without secondary venting, designed for direct installation into manifolds. This cartridge regulator is largely found in ventilators.

We offer high-flow and low-flow versions of this regulator as a flexible solution to meet customer requirements. We use special materials to ensure it can be used in the most sensitive equipment. This regulator is FDA compliant, and is oil, lubricant, silicon and phthalate-free.

DR.032 S | Pressure regulator with hose connectors

Compact 6 mm diameter membrane pressure regulator without secondary venting. This regulator is especially designed for water applications, such as dialysis machines, dental equipment and water treatment plants. The PPSU plastic casing means it can be used in special applications in temperatures of up to 95°C. It complies with FDA and German Federal Environment Office standards, and is oil, lubricant, silicon and phthalate-free.
