Materials: Polysulphone, polyurethane, NBR, EPDM, acetal, stainless steel Temperature range: +4°C to max. +66°C Setting accuracy: 2.5 mbar Note: For cleaning or sealing, do not use any dissolving medium! Type Thread RP 50 VU M5 22 --- -0.35 to 0 bar RP 50 VU H M5 22 --- -0.85 to 0 bar 78 29 The ideal vacuum regulator for small volume flows! TIP Vacuum regulators - precision versions 4 - 48 m³/h Suitable: These vacuum regulators can be used for pressure regulation in the vacuum range as well as in the overpres- sure range. Materials: Body: Aluminium die-casting, internal parts: Stainless steel/brass, diaphragms: NBR and Dacron Temperature range: -40°C to max. +90°C These vacuum regulators allow controlling the vacuum as a bypass or using shut-off technology. 1. Bypass adjustment*: This adjustment should be used, if an existing vacuum must be reduced by delivering compressed air. Recommended for adjusting large vacuum quantities. 2. Stop adjustment*: The vacuum is pulled and adjusted by the regulator. Once the desired value is reached, the regula- tor is closed. Recommended to save vacuum energy.

RP 14 VU W --- Pneumatic adjustment manual adjustment Vacuum regulators without external leakage 6 - 160 m³/h Suitable: Using these vacuum regulators it is possible to accurately regulate a vacuum without needing external lea- kage. They are used in vacuum systems where individual consumer units need to be supplied with different levels of va- cuum. Adjustment: The configuration is carried out using a knurled screw or via a pneumatic signal.

It is used to adjust a vacuum system with the same operating vacuum. The set- ting is done using a fine thread of the valve and the mechanical opening due to the spring load.
