Parts in body valves
In the so called Parts-In-Body valves, moving components are installed directly into the manifold.This specific solution is designed for lifting machines, earth moving machines, agricultural application and industrial vehicles.
Pressure control valvesBelong to this type the valves meant to limit or reduce working pressure inside an hydraulic circuit. Inside this chapter there are also the sequence valves and the proportional pressure reducing valves.
Counterbalance valvesCounterbalance valves are auxiliary valves, to be installed directly on hydraulic actuators (cylinders and hydraulic motors). Thanks to their configuration, these valves hold the loads, are able to limit maximum pressure inside hydraulic actuators and regulate lowering velocity in function of flows coming out of directional control valves. Parts-In-Body counterbalance valves can be: simple or double effect, in line or flange-mounted, with or without pilot dampers, high/low pilot ratio, for regenerative circuits, with open-centre or close-centre spools, etc.
Check valvesThey are auxiliary valves, to be installed directly on hydraulic cylinders, to prevent any movement due to external forces. Cylinders unlock is obtained through an inner pilot pressure which brings about the on/off opening. Parts-In-Body check valves can be: simple or double effect, in line or flange-mounted, with two position manual shut off, etc..
Hose burst valves (ISO8643)
They are auxiliary valves, to be installed directly on hydraulic lifting cylinder in earth moving machines.
They are meant to prevent the effects of a possible hose failure on the carrying circuit, according to the requirements fixed by the international standard ISO-8643*.
According to their configuration or type of application on which they are mounted on, they can be piloted 1) by pilot pressure 2) or by pressure picked up from the cylinder's chamber opposite to the side which the valve is installed on.
* The conformity to ISO8643 is obtained by setting the components directly on the equipment. The machines' manufacturer or retrofit installation firms are bound to certificate results of the conformity test.
Parts-In-Body flow control valves main characteristic is that setting and compensation components are installed inside a collector,
so that this type of valves can be mounted directly on the hydraulic circuit..
According to their adjusting device, there can be two types of Parts-In-Body flow control valves: electro-proportional flow regulators and manually adjustable flow regulators.
Among manual adjustable regulators are auxiliary regulators for earth moving machines, drawn to feed hammers or auxiliary actuator.
