Bleeding and venting valves exhaust air or gases from plants orpipelines without requiring external power supply. Under working pressure they operate as continuous bleeding valve, when the system is drained they act as venting valve. If, in case of a pump failure, a considerably larger air quantity is to be put in, an additional vacuum breaker with large seat diametre has been integrated. Owing to its very big and adjustable vacuum breaker, the EB 1.57 is particularly suitable for water engineering plants subject to vacuum hazards.
Top and bottom sections of the valve body are connected by a clamp ring and two bolts. Servicing/maintenance is easy and does not call for special tooling. The vacuum breaker has been integrated in a similarly easy way.
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.
