7 Awarning sign is affixed to the yoke arm near the name gate valves with pressure seal bonnet are factory-supplied with aclosed connection branch (part ) with connection dimensions 22/ (suitable for pipe ).When ordering please state whether a pressure relief valve is to beprovided,orwhetherexcesspressureistobe releasedviaabypassorarelief hole in the inlet-side seat ring (515). In those cases, the gatevalves can be used for one flow direction NOTE:The pressure relief valve must not be welded directly to theconnection branch (part No.)
