summary:

PVG 32 is a load sensitive hydraulic valve designed to provide maximum flexibility, with a wide range of products ranging from simple load sensitive directional valves to load independent electrically controlled proportional valves. The modular design of PVG 32 allows for the assembly of a set of valve assemblies to accurately meet customer needs. Regardless of the combination form, the valve assembly will still maintain a compact external size.

• Load independent flow control: ‒ The fuel supply flow rate of a certain actuator is independent of its load pressure ‒ The fuel supply flow rate of a certain actuator is independent of the load pressure of other actuators

• Good characteristics

• Energy saving

Each valve group can be equipped with up to 12 working modules

• Multiple thread specifications

• Lightweight

• Compact design and installation

PVP， Pump side module

• Built in overflow valve

• Pressure tap

• Type:

Open core, used for quantitative pump systems

Closed core, used for variable displacement pump systems

Provide a pilot oil source for the electronic control module

Provide a pilot oil source for the hydraulic control module

‒ Can be connected to the electrically controlled LS unloading valve (PVPX)

PVB， work module

• Interchangeable valve core

According to the requirements, the types of basic modules are:

Integrated pressure compensator in P channel

Integrated load failure check valve in P channel

A and B ports with buffer/oil replenishment valves

The A and B ports are equipped with LS pressure limiting valves that can be adjusted separately

Different specifications of valve cores are interchangeable

All types are suitable for mechanical, hydraulic, and electrical drives

PVG32 valve group with open core PVP (quantitative pump), PVB with flow control spool

When the pump is started, the main valve cores of each working module (11) are in the neutral position, and hydraulic oil flows out of the pump, passes through the oil port P and the pressure regulating valve core (6), and returns to the oil tank. The flow rate of hydraulic oil through the pressure regulating valve core determines the pump pressure (to be pressurized). When one or more main valve cores are activated, the highest load pressure is fed back to the spring chamber behind the pressure regulating valve core (6) through the shuttle valve circuit (10), and the return oil port is partially closed. The pump pressure is applied to the right-hand side of the pressure regulating valve core (6). Once the load pressure exceeds the set value, the relief valve will open, allowing a portion of the pump flow to return directly to the oil tank. In a working module with pressure compensation, whether the load changes or the module with higher load pressure is driven, the pressure compensator (14) can maintain the pressure drop of the main valve core unchanged. In a working module without pressure compensation, a one-way valve (18) is integrated into the P channel to prevent hydraulic oil from flowing back. In the case where the working module has a balance valve externally, the P channel may not have a one-way valve. The buffer valve PVLP (13) (with a fixed set value) and the oil replenishment valve (17) at ports A/B are used to protect various working components in the event of overload and/or cavitation. The A/B ports of the working module with pressure compensation can be equipped with an adjustable LS pressure limiting valve (12) to limit the pressure of each working oil circuit. Please refer to section PVG 32 on page 8 for a better understanding of this example.
