7 There is a danger of the liquid trapped inside the valve body heating upand causing an unacceptable pressure increase inside the valve. 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).

8 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. ) but must be connected to it viaan intermediate pipe (part No. 710) in a vertical, upright positionoutside the insulating material. The minimum distance to theinsulation is 200 *) (710)Connection branch ( )InsulationBody pressure relief valve forboth flow directionsPipe union (731)*) The pipe between the connection branch and the pressure relief valve isnot included in KSB s scope of (100)Pressure relief hole in inlet-side seat ringWhen connecting to a pipe (710)

Ifa bypass is necessary or requested for other reasons, a NORI 320/NORI ,DN15( )orDN25(forgatevalvediameterfrom 175 mm), is fitted in the bypass line as a standard (larger nominal sizes on request).
