Many directional valves for high-pressure applications are designed as seated valves. These are zero-leakage and completely resistant to fluid contamination. The HAWE product range also includes other types of valve that allow you to safeguard or regulate the system pressure.
The valve bank type VB consists of several directional seated valves, connected in parallel. As a ball valve, it is tightly sealed with zero leakage in the closed state. 2/2, 3/2, 4/2, 3/3 and 4/3 directional seated valves can be provided. The valve bank can be fitted directly onto hydraulic power packs with connection blocks.
Pmax: 700 bar
Qmax: 120 l/min
This is a zero-leakage, ball seated valve. 2/2, 3/2, 4/2, 3/3 and 4/3 way functions are available. A suitable connection block makes a direct pipeline connection possible. The directional seated valves can also be provided as chained valves in a valve bank type VB.
Pmax: 700 bar
Qmax: 120 l/min
This is a zero-leakage, cone-seated valve. 2/2, 3/2, 4/2 and 4/3 way functions can be provided. Equipped with the NG6 (Cetop 3) standard connection pattern, the NBVP allows operating pressures of up to 400 bar. Additional options such as position monitoring and a 12 W solenoid are also available.
Pmax: 400 bar
Qmax: 20 l/min
The BVP17-type directional seated valve can be operated as a 2/2, 3/2, 4/2 or 4/3-way valve at operating pressures of up to 700 bar. Direct actuation options include electro-magnetic, pneumatic and manual (hand lever).
Pmax: 700 bar
Qmax: 20 lpm
Pressure-limiting valves reliably protect the hydraulic system from being subjected to excessive system pressure. The MV type comes in a wide range of designs and pressures of up to 1000 bar for the high-pressure range.
Pmax: 700 bar
Qmax: 160 lpm
This valve can be actuated using electric proportional control. It is used for pressure limitation, and also to limit the load pressure on the actuators in the system. It is available as a manifold mounting and as a piping insert valve.
Pmax: 700 bar
Qmax: 120 lpm
The RHC-type check valve is available as an insert valve in 6 different sizes. Thanks to its range of pilot ratios and optional hydraulic release, it can be used in similar applications to load-holding valves.
Pmax: 700 bar
Qmax: 200 lpm
