EB1-10 & 1-11 CONTINUOUS BLEEDING AND VENTING VALVE

Bleeding and Venting Valves

Mankenberg Industrial Valves

Bleeding and venting valves remove air or gases from systems or pipelines without requiring an external energy input. When a system is drained they act as venting valves; venting may be prevented by fitting a non-return valve.

The EB 1.10 and EB 1.11 bleeding/venting valves are float-controlled robust valves made of spherical-graphite cast iron or cast steel to handle large air volumes e.g. in sand filters. The internal components are made of stainless steel featuring excellent corrosion resistance. Up to 130 °C the valve cone is fitted with a soft seal; up to 200 °C the seal is metallic.

EB 1.11 is fitted with an external float and specially suitable for foaming and contaminated media.

The simple design makes it easy to specify, install, handle and service these valves in an industrial environment. Valves for continuous bleeding must not be overdimensioned. If a larger valve size is selected, a higher working pressure range with a correspondingly lower flow volume should be chosen. In case of doubt we shall be happy to advise you.

On filter vessels the bleed connection is often located in the middle of the vessel. If the flow volume is large and the distance between distribution funnel and bleed connection small, the incoming water jet hits the bleed connection. This will impair the efficiency of the bleed valve and can result in water hammer. This problem may be avoided by installing a baffle or by placing the bleed connection away from the centre.

For the EB 1.11 the supplied float rod guide is to be installed in such a way that the float rod will be vertically guided. It must not obstruct the lift movement of the float.
