They are of all steel design andall functionally essential internal parts are hardened and run maintenance free in oil; Cones and seats are 7400 page 2 BVP 3 Z - H 1/4 BVP 3 R(S) - H 1/4 BVP 3 Z - PBVP 3 R(S) - versions, main dataOrder examples:BVG 3 R/B 2,5 - WG 230 BVP 3 Z- PComplete symbols (The actuation symbols applyto all flow symbols)Pipe connectionBVG 3 R - H BVG 3 S - PBVG 3 Z - 3 Z - mountingTable 2: SymbolsRSZT able 1: Basic type and size 1)CodingBVG 3 BVP 3 Design and connectionPipe connection G 1/2 ISO 228/1(BSPP)Manifold mountingFlowQmax(lpm)5050 Pressurepmax(bar)320320 BVP 3 Z - HBVP 3 R(S) - HBVP 3 Z - 3 Z - 3:Orifices(in ports A, B, and C, see also sect.

Flow limitationThe max. flow has to be limited (depending on the pressure) by means of orifices in the caseof accumulator circuits or if connected to high pressure circuits (circulation lines or centralsupplies) down to the specified Qmax(see sect. 2). These orifices must be located always on the accumulator side. With valves type .. theyare installed in port C. If mounting in port A or B is requested, this has to stated in uncoded text.
