2- and 3-Way Flow Control Valve MTKK / MTKL
Description
Series MTK.. 2/3-way flow control valves provide a constant, pressure-compensated, flow of hydraulic fluid. Any surplus inlet flow can be used elsewhere. The constant flow setting can be fixed or adjustable.
The individual units can be block-mounted; the required number of individual functions can be assembled into one valve block without any interconnecting pipework.
Valve blocks can incorporate both series and parallel circuits.
2- and 3-Way Flow Control Valves, Series LVM
Description
Series LVM flow-control valves are used to set the speed of single-acting hydraulic actuators
There are 3 versions of the flow-control valve:
- Load Sensing (LS) pumps without 2-way pressure compensator
- Load Sensing (LS) pumps with 2-way compensator
- Fixed-displacement pumps with integral 3-way pressure compensator
2- and 3-Way Flow Control Valves, Series SRCB
Description
The flow-control valves in this series are used to set the working speed of motors and cylinders, the setting being load-independent, i.e. pressure compensated. The flow rate is set by a slit-type orifice that is adjusted by a proportional solenoid.
2- and 3-Way Flow Control Valves, Series SRR
Description
Series SRR.. flow-control valves are used to set the working speed of motors and cylinders, the setting being load- independent, i.e. pressure compensated. They divide the inlet flow into a constant-flow portion and a surplus-flow portion.
The surplus flow can be pressurised and can therefore be supplied to a second actuator. This valve can also be used as a 2-way flow control valve by plugging the surplus flow outlet port.
2-way Flow Control Valve MTKE / MTQE
Description
Series MTKE and MTQE flow control valves are monoblock designs with an integral flow divider. They divide the flow entering at port P into a constant flow portion (A) and a surplus flow (T). The constant flow rate is manually adjustable with a hand-knob.
Via a 2-way ON/OFF valve, the entire supply flow can be diverted to tank with virtually no back-pressure. A pressure relief function for the constant flow can be incorporated. The unique advantage of these flow control valves is that the constant flow setting is maintained even after the valve has been switched off.
Flow control valves in the MTKE series can be mechanically switched over for use with Open Centre or Closed Centre systems.
3-Way Flow Control Valve MTKA
Description
Series MTKA priority flow control valves provide a constant, pressure-compensated, flow of hydraulic fluid in one direction. They divide an inlet flow into a constant, priority, flow and a surplus flow. The surplus flow can be pressurised and can therefore be supplied to an additional actuator.
The valve can also be used as a 2-way flow control valve by plugging the surplus flow.
3-Way Flow Control Valves, Series SRCA
Description
The flow-control valves in this series are used to set the working speed of motors and cylinders, the setting being load-independent, i.e. pressure compensated. The flow rate is set by a slit-type orifice that is adjusted by a proportional solenoid.
Check Valves DERV
Description
Series DERV pilot-operated check valves lock a cylinder in any rest position.
They are intended for direct mounting in the cylinder.
Check Valves ERV
Description
ERV 8, ERV 8-600:
These pilot-operated check valves are size 8, two stage, high performance screw-in cartridges with an (ERV 8: M30x1.5 / ERV 8-600: M34x1.5) mounting thread. The conical-seat design ensures that the cartridges are leak-tight from B → A. The check function can be overridden by applying a suitable pilot pressure at port X. In the A → B direction, flow can pass freely through the valve (opening pressure = 2.5 bar). These screw-in cartridges are predominantly used in certain mobile and industrial applications to maintain the position of loaded actuators (e.g. outrigger cylinders) after the pump pressure has been disconnected.
