These directional seated valves use spring loaded balls as valve elements and therefore do not show any leakage. They are manifold mounting and are available with various actuations which always act on an angled lever pushing the valve element in the desired switching position.
The basic versions are designed as 2/2- and 3/2-way directional valves. 3/3- , 4/3-way functions are possible, if two valves are housed in one valve body, whereas 4/2-way functions require an additional intermediate plate. The enforced versions G39, G49, G..-22 are intended for pulsating, permanent load with frequent switching operations in the high pressure range.
These valves may be directly installed in pipe systems, when equipped with subplates enabling pipe connection. Many optional functions can be incorporated in these sub-plates e.g. pressure limiting valve or restrictor check valve for widen the field of application for this valve type. Valve banks of these valves are also available featuring several valves
connected in parallel (see type VB).

BREVINI HYDRAULICS was formed in 1996 and it is the youngest company of Brevini Group.
With their integrated digital electronics, the HPV load-sensing proportional valves and the MPE range of joysticks, provide solutions with the latest generation in control.
All the components, (mechanical and electrical) are of exclusive in-house design and the mechanical-hydraulic components are covered by 4 international licences.
There are two available sizes: HPV41 and HPV77 with capacity of 140 and 240 litre/min (37 – 36 gpm).
Both versions are available with ATEX conformity and they can be supplied with manual, hydraulic and electric controls.
These valves find application in many different areas:
Drills, railway-building machines, shredders, sweepers, shipyard cranes and off shore, municipal machines, building yard machines (concrete pumps), aerial platforms, forestry machines and so on. |

The directional spool valve bank type PSL is designed for constant delivery pump systems (pressure/flow controller) whereas the type PSV is for variable displacement pump systems. Both are available in three sizes.
They serve to control the direction of motion and provide infinite control of the speed of motion of hydraulic consumers regardless of their load. Several consumers may be operated simultaneously and independantly of each other.
The main field of application is mobile hydraulics (e.g. crane controls etc.).
These valve banks can be tailored to a specific application, requiring unequal max. consumer flows at port A and B as well as additional functions such as functional cut-off. |

| The seated valves are direct operated. Depending on the desired control function up to four valve cartridges are used. The poppets which are situated in the cartridge are pressed on the valve seat via springs or are opened via tappets. Hardened poppets and valve seats ensure long life. Pressure compensated poppets reduce the operating power. |

| Aron, a member of the Brevini Group, manufactures hydraulic components and manifold systems. The range of products includes Cetop components, related modular and proportional components, as well as electronic circuit boards, but the single and modular 6-way flow dividers deserve special mention. The sophisticated design of these parts make them ideally suited to a wide variety of applications, especially in agriculture. With a flow rate capacity of 20 to 80 lpm (5.3 to 21.1 gpm), this range is best suited to applications such as front loaders, mixer buckets, irrigator bars and other agricultural equipment in general, ensuring very limited pressure loss in relation to the performance delivered. Zinc plated versions are also available on request for use in particularly harsh conditions. |
