HAWE Harvey hydraulic product introduction
HAWE Harvey hydraulic products
HAWE Harvey R series radial piston
pump
The R-type radial piston
pump is composed of a valve-type star-arranged plunger cylinder. Large flow output can be achieved with a parallel configuration of up to 6 rows of plunger cylinders.
In general, the motor drives the
pump and is coupled to the
pump via flanges and couplings. Of particular interest is the fact that the
pump can be derived from multiple pressure outlets.
Maximum pressure Pmax=700bar Maximum flow rate Qmax=91.2l/min
HAWE Harvey LHK series balancing valve
The balancing valve is a pressure valve that controls the pressure on the return side of the two-way actuator.
It maintains the oil return lock at its set pressure (set pressure is greater than 15% of the maximum load pressure) and overcomes the moving load pressure. Only the residual pressure forces the
pump to "push" and draw the medium in the valve to unload.
Maximum pressure Pmax=450bar
Maximum flow rate Qmax=250 l/min
HAWE Harvey HC series compact hydraulic
pumping station
The HC type electric compact hydraulic
pump station only needs to be connected and connected, and can be widely used in the small-flow hydraulic control circuit of intermittent work. For example: machine tools, work clamps or general machinery. The
pump station is constructed by integrating the outer casing (ie the fuel tank) and the motor and
pump. Maximum pressure Pmax=700bar Maximum flow rate Qmax=12.9l/min
HAWE Harvey SG, SP type spool valve type reversing valve
HAWE Harvey SG, SP type spool valve type reversing valve has two structural forms, namely SG type pipe connection type with or without overflow valve and SP type plate connection type, and there are 5 specifications, they can be used to control The direction of movement of the different actuators (oil motor and cylinder). This sturdy and versatile directional control valve can be configured with a variety of different handling methods to meet the requirements of various applications (such as ships, mobile machinery, etc.). The maximum pressure Pmax = 200 to 400 bar. The maximum flow rate Qmax = 12 to 100 l/min.
HAWE Harvey SF, SD, SK, SU type speed control valve
HAWE Harvey SF, SD, SK, SU type speed control valves can be delivered as two-way and three-way speed control valves. They provide stepless adjustment of hydraulic system flow, while the SU-type speed control valve can be used for constant flow regulation in two stages. The flow coefficient does not depend on hydraulic system pressure and medium viscosity and is steadily maintained within its minimum tolerance. Special requirements can be met by integrating other functional valves such as relief valves, unloading valves or with an external Z port. A two-way speed control valve with a bypass check valve and a bridge circuit in any flow direction is also available. A variety of operating modes make this speed control valve more widely used. Maximum pressure Pmax = 315 bar Maximum flow rate Qmax = 0.3 to 130 l/min.
HAWE Harvey RK/RB, RC, RE, ER type check valve
HAWE Harvey RK/RB, RC, RE, ER type check valves are classified as shut-off valves. They enable the oil circuit to open in one direction and close in the opposite direction. The RK/RB type check valve is a spring-loaded, solid-structured ball-type globe valve that is insensitive to dirt. The RC type check valve is a two-threaded, spring-loaded disc type check valve. It not only cuts off oil flow from one direction, but also acts as an oil suction valve installed in the
pump suction pipe. The mounting holes for all threaded cartridge check valves can be machined with a conventional twist drill (acute angle 118 degrees). The ER type threaded cartridge type check valve is a spring loaded ball type globe valve, which is mainly used for the stop valve plate type superposition combination. Maximum pressure Pmax = 400 to 700 bar Maximum flow rate Qmax = 6 to 120 l/min.
