Description

The proportional valves are used to control direction and flow in hydraulic systems. The applications of these valves ensure any motion sequences at low cost. The PVS valve is a directly controlled spool valve, actuated by proportional solenoids, in five chamber design. The flow rate is proportional to the solenoid current and remains constant with varying pressure. The counterbalance effect ensures that load does not go out of control.

The large flow range is achieved by a variable orifice, which changes proportional to the pressure drop. The sliding spool orifice is in the side body.

Application

Examples are acceleration and deceleration move-ments which are difficult to realize with common hy-draulic components. PVS valves are characterized by their large flow range. Thereby they are particularly suitable for demanding tasks, e.g. feed control, robo-tic systems, handling operations, etc.

The proportional valves are used to control direction and flow in hydraulic systems. The applications of these valves ensure any motion sequences at low cost. The PVD valve is a directly controlled spool valve, actuated by proportional solenoids, in five chamber design. The flow rate is proportional to the solenoid current and partly load-compensated.

Application

Examples are acceleration and deceleration move-ments which are difficult to realize with common hy-draulic components. Furthermore with these valves, electric remote controls with manual potentiometer could easily be done. When large control range and optimal load compen-sation is requested we recommend the AROFLEX-proportional directional control valve PVS.

Proportional pressure relief valve NG6 EPDB-06



Description

EPDB The direct operated proportional pressure relief valve is built as a slip-in cartridge fitted in a connecting flange. By adjusting the electric current to the solenoid the operating pressure changes proportionally. When the operating pressure is reached, the poppet spool opens and connects the protected line to the tank. Back pressure in T influences thereby the pressure in the protected pressure lines. These pressure relief valves are built according to the differential spool principle and are therefore very sensitive adjustable over the whole pressure range and also suitable for systems with extremely low minimum pressures.

The valves have their applications in hydraulic sys-tems in which the pressure frequently has to be changed. The facility for remote control and signal processing from process control systems enable economical solutions for repeatable sequences. EPDB INVERSE Direct operated proportional pressure relief valve. A spring force works against the hydraulic pressure. With solenoid deenergized the maximum operating pressure is present. The force of the proportional so-lenoid counteracts the spring force. With increasing solenoid current the operating pressure declines (in-verse function).

Proportional pressure relief valve NG6 PEPDB-06


direct operated Qmax = 25 l/min pmax = 400 bar pNmax = 350 bar

Description

The direct operated proportional pressure relief valve is available in flange and sandwich construction ac-cording to ISO 4401-03. Incorporated is a proportion-al pressure relief cartridge size M22x1,5 according to ISO 7789. By adjusting the electric current to the solenoid the operating pressure changes proportionally. When the operating pressure is reached, the poppet spool opens and connects the protected line to the tank. Back pressure in T influences thereby the pressure in

the protected pressure lines. These pressure relief valves are built according to the differential spool principle and are therefore very sensitive adjustable over the whole pressure range and also suitable for systems with extremely low minimum pressures. The valves have their applications in hydraulic sys-tems in which the pressure frequently has to be changed. The facility for remote control and signal processing from process control systems enable economical solutions for repeatable sequences.

Proportional pressure relief valve EPDB-06-Exd-L15



Description

EPDB The direct operated proportional pressure relief valve is built as a slip-in cartridge fitted in a connecting flange. By adjusting the electric current to the solenoid the operating pressure changes proportionally. When the operating pressure is reached, the poppet spool opens and connects the protected line to the tank. Back pressure in T influences thereby the pressure in the protected pressure lines. These pressure relief valves are built according to the differential spool principle and are therefore very sensitive adjustable over the whole pressure range and also suitable for systems with extremely low minimum pressures.

The valves have their applications in hydraulic sys-tems in which the pressure frequently has to be changed. The facility for remote control and signal processing from process control systems enable economical solutions for repeatable sequences. EPDB INVERSE Direct operated proportional pressure relief valve. A spring force works against the hydraulic pressure. With solenoid deenergized the maximum operating pressure is present. The force of the proportional so-lenoid counteracts the spring force. With increasing solenoid current the operating pressure declines (in-verse function).

Proportional pressure reducing valve NG6 DRV-06



Description

The proportional pressure reducing valve (3-way function) is used to control pressure and direction in hydraulic systems, where the pressure frequently has to be changed. Proportional to the solenoid current, solenoid force and pressure in port A or B rises. With deenergized solenoid, port A and B are connected to port T (throttled). The valve function is practically in-dependent of the pressure in port P.

The proportional pressure reducing valve can be de-livered with 1 or 2 solenoids. For pressure reducing only in A or B, it needs only one solenoid. For pres-sure reducing in A and B, it needs two solenoids.

Application

A typical application is for example a pilot valve for larger proportional directional control valves.

Emergency shut off valve NG6 42W-06-…-SSM


manually operated pmax on P, A and B = 350 bar pmax on T = 150 bar Q = 12 l/min

Description

The manually operated 4/2 way valve is often used as a 3/2- way pilot valve to shut off bigger valves. The spool of the valve is held in normal position by spring-loaded balls.

In the actuated position is the valve locked. In order to reset the valve, the green sleeve must be pushed towards the valve body while simultaneously pulling the red push-knob back to its rest position. The valve is protected for use in seawater atmos-phere. Thereby it is an all-purpose valve.

Description

Direct operated solenoid poppet valve. They are ap-plied where an absolutely leak free closing of the valve is essential like in load holding-, clamping- or gripping functions. These valves are suitable for haz-ardous areas in off-shore and shipbuilding applica-tions as well as in the chemical-, oil- and gas indus-try.

Function

The pressure tight switching solenoid and in turn the spring on the opposite side shift the guided poppet into an either open or closed position. Due to the equal-area- and balanced poppet design there are no undesired opening or closing forces. Fluid may pass the poppet valve in both directions. The poppet pis-ton is sealed by an o-ring. The seat with metallic seal closes leak free in both directions.
