1 -STP FLOW CONTROL VALV WITH SHUT-OFF VALV HFD WITH PRSSUR COMPNSATION, WITH PRSSUR AND TMPRATUR COMPNSATION This is a compound valve built by assembling a flow control valve with pressure, a shut off valve and a check valve. It is used to control the feed operation (rapid feed slow feed rapid return) of e.g. a machine tool. Features. The valve is compactly designed and is suitable for feed control of singlepurpose machine tools and automatics.. Since the valve incorporates a pressure mechanism, it keeps the controlled flow constant regardless of the pressure variation at the and ports. If a valve equipped with the temperature mechanism in addition to the pressure mechanism is used, the valve can keep the controlled flow constant even if the fluid temperature (viscosity) varies.. The flow is controlled almost in direct proportion to the division on the flow adjusting dial. To achieve good pressure performance, the pressure difference between the and ports must be maintained at 0. MPa or larger. The valve mounting face must be finished to the same surface finish.z as the valve face. The edge angle of the dog (cam) must be deg. or smaller. The roller must have a hardness in the range HRC to HRC. When controlling slow feed rapid feed in feed operation, it is necessary to apply a back pressure of approximately 0. MPa at the port for the internal drain type or at the DR port for the external drain type. Description of the model designation The pressing-down force varies according to the back pressure as shown in the table to the right. If the circuit is configured so that the back pressure ( port pressure) becomes high with the internal drain type, the back pressure must be MPa or lower since No. high back pressure will shorten the life of the roller and the pin. of main valve Operating method of sub valve M: Pressing-down type Pressing-down force : Normally open internal drain Back pressure ( ) : Normally open external drain Back pressure ( ) Check valve Back pressure ( ) With pressure With pressure and temperature Internal drain type With pressure With pressure and temperature Piping method G: Gasket Function category P: With pressure K: With pressure and temperature of main valve : MPa : MPa Directional control valve (sub valve) Flow control valve (main valve) 0 Pressing-down force (N) 0 NOT: The pressing-down force value in the specification table indicates the value when the back pressure is F 0 F 0 F 0 F F F F 0 F 0 F 0 F F F 0 F 0 F 0

The valve is compactly designed and is suitable for feed control of singlepurpose machine tools and automatics.. Since the valve incorporate a pressure and temperature mechanism, it keeps controlled flow constant regardless of the pressure variation at the and port and the viscosity variation due to temperature change.. The flow is controlled almost in direct proportion to the division on the flow adjusting dial. To achieve good pressure performance, the pressure difference between the and ports must be maintained at 0. MPa or larger. The valve mounting face must be finished to the same surface finish.z as the valve face. The edge angle of the dog (cam) must be deg. or smaller.

9 HFD WITH PRSSUR AND -STP FLOW CONTROL VALV WITH ROTARY TYP SHUT-OFF VALV TMPRATUR COMPNSATION) This is a compound valve built by assembling a flow control valve with pressure and temperature, a shut off valve and a check valve. It is used to control the feed operation (rapid feed slow feed rapid return) of machine tools, etc. Features. The switching mechanism for the shut-off valve has been changed from the conventional spool forcing down type to the spool rotation type.. The dog pressing force can be lightened since the spool rotating force does not change even if the port pressure (back pressure) varies.. This valve can also be used for light bed feed control since it can control rapid feed st step feed simply. To achieve good pressure performance, the pressure difference between the and ports must be maintained at 0. MPa or larger.. Z The valve mounting face must be finished to the same surface finish as the valve face. The dog section pin ( 9 0. mm) must have a hardness in the range HRC to HRC.
