Directly operated pressure relief valves VPP-04 HA 5093 /003 Size 04, 06 p max up to 30 bar Q max up to 40 L/min Replaces HA 5093 3/00 Screw-in cartridge, modular and in-line design Six pressure ranges Pressure adjustment option: - screw with internal hexagon Functional Description Pressure relief valves VPP-04 were designed for applications requiring a safely valve or a pressure regulating valve working over a wide range of pressures and flow rates. The valve basically consists of the valve body (), poppet with damping spool () and compression spring (3). The spring pushes the poppet onto the seat (5) holding the valve in its normally closed position. When the force, caused by the pressure acting on the exposed surface area of the poppet, exceeds the spring force, the valve opens and and the flow passes from port P to port T. To optimize the valve performance, six pressure ranges are available. Choosing the closest range is recommended. The design enables the valve to be used as a screw-in cartridge for manifold mounting, or in a subplate and/or in-line mounted housing. The valve body and the adjustment screw are zinc coated. With models M and R the valve bodies are phosphate coated.

Pilot operated pressure relief valve VPN-06 HA 56 /003 Size 06 p max up to 30 bar Q max up to 70 L/min Replaces HA 56 3/00 Cartridge, modular and in-line design Five pressure ranges Two pressure adjustment options: - screw with internal hexagon - hand knob with arrestment Functional Description Pressure relief valves VPN are pilot operated pressure valves designed for system pressure limitation. The pressure adjustment provides the adjustment screw (4). In its basic state, the valve is closed. The pressure acts on the face area of the control spool () and at the same time through orifice () on the control spool rear side, which is preloaded by a spring and further on through orifice (3) on the pilot valve ball (6). When the increasing system pressure reaches the value, which is preset by spring (5), the valve opens and the control flow passes through the pilot valves. The spool area which is preloaded by the spring becomes relieved, the spool control edge opens the radial bores in bushing (7) and the fluid passes from port P to T.The control flow is routed through groove (8) to channel T. Valve adjustment can be lockwired (9). The valve body and the adjustment screw are zinc coated. With models M and R the valve bodies are phosphate coated. P T

The pressure adjustment is controled by the adjustment screw (4). In its basic state, the valve is closed. The pressure acts on the face area of the control spool () and at the same time through orifice () on the control spool rear side, which is preloaded by a spring and further on through orifice (3) on the pilot valve ball (6).

The spool area which is preloaded by spring becomes relieved, the spool control edge opens the radial bores in bushing (7) and the fluid passes from port B to T. The control flow is routed through slot (8) to port T. When an accurate pressure control, which does not depend on pressure variations in port T (only for models RC and RC3, see Functional Symbols), is required the model "Y" with external port for pilot flow is to be used. If a relieving of the valve on a lower pressure as that set up by the spring (5) is needed, the model with port "X" (0) is to be used. The valve body and the adjustment screw are zinc coated.

Directly operated pressure reducing valves VRP-04 HA 54 5/005 Size 04... 4600 PSI (30 bar)... 5.3 US GPM (0 L/min) Replaces HA 54 6/003 For stacking assemblies 4 pressure ranges Pressure reduction in ports A or P Model A with check valve Installation dimensions to ISO440/CETOP-RP H Functional Description The pressure valves VRP are directly operated reducing valves for vertical stacking assemblies designed as 3-way valves, i.e. with pressure protection of the secondary circuit. The valve consists of the valve body (), control spool (), spring (3), adjustment element (4) and the plug G /4 (5) for pressure measuring and, if necessary, of a check valve. Model A With this model, the fluid enters into the valve body from the primary circuit through port A and passes through the metering edge, where its pressure is reduced.the reduced pressure corresponds with the setting of the control spring.at the same time, this pressure affects also the surface area of the control spool opposed to the spring (the pressure can be measured at the port G /4 which is normally closed by plug 5).Thus the static balance of the spool is ensured.if the reduced pressure changes, a respective control action takes place and the reduced pressure returns to its preset value.the flow from the output port A passes then to the user.if pressure behind the valve increases due to the effect of the load acting on the user, the spool shifts further against the spring until the second metering edge opens and the excessive flow drains through port T.The leakage from the spring room is also routed to port T. The reverse free-flow from port A to port A passes through a check valve which is connected parallel to the metering edge. Model B With model B, the pressure reduction follows from port P to port P, but it takes place only when the flow in port B passes in the direction to the user (not opposite).the protection of the secondary circuit is also ensured for one flow direction only. Model P With model P, the pressure reduction follows from port P to port P, but is effective in both flow directions through the directional valve (as well as the protection of the secondary circuit). The valves are delivered with basic surface treatment. The valve body is phosphate coated, whereas the surfaces of the other parts are zinc coated. A B A B
