PVG-EX Introduction

The Danfoss PVG-EX program is an explosion-proof PVG designed to be used in Ex hazardous areas like mining and oil and gas industries.

Product certification

The PVG-EX is developed according to and in compliance with:
EU Directive 2014/34/EU Equipment for explosive atmosphere - ATEX
•
EN 60079-0:2018 Electrical apparatus for explosive gas atmospheres-part 0
•
EN 80079-36:2016 Non-electrical equipment for explosive atmospheres – Basic method and requirements
•

•
EN 80079-38:2016 Equipment and components in explosive atmospheres in underground mines

PVG-EX 32/128/256 Safety in Systems

All types and brands of control valves, including proportional valves, can fail. Therefore, the necessary protection against the serious consequences of a functional failure should always be built into the system.
General safety considerations
For each application an assessment should be made for the consequences of the system in case of pressure failure and uncontrolled or blocked movements.
Warning
Because the proportional valve is used in many different applications and under different operating conditions, it is the sole responsibility of the manufacturer to ensure that all performance, safety and warning requirements of the application is met in his selection of products and complies with relevant machine specific and generic standards.
Control system example
An example of a control system using an aerial lift is shown below:

PVG-EX Introduction
Aerial lift
This example breaks down the control system into smaller bits explaining the architecture in depth. Even though many Danfoss components are used in the PVG control system.
The function of the control system is to use the output from the PVE together other external sensors to ensure the PLUS+1 main controllers correct function of the aerial lift.
Electrical block diagram
Warning
It is the responsibility of the equipment manufacturer that the control system incorporated in the machine is declared as being in conformity with the relevant machine directives.

PVG-EX Introduction
Caution
A mix of electrical actuation and hydraulic actuation on the same valve stack is not safe. PVE and PVH are designed for different pilot pressure.
Cost-free repairs, as mentioned in Danfoss General Conditions of Sale, are carried out only at Danfoss or at service shops authorized by Danfoss.

Warnings

Warning
All brands and all types of directional control or proportional valves, which are used in many different operation conditions and applications, can fail and cause serious damage.
Analyze all aspects of the application. The machine builder/system integrator alone is responsible for making the final selection of the products and assuring that all performance, safety and warning requirements of the application are met.
The process of choosing the control system and safety levels is governed by Machinery Directive 2006-42-EC, and harmonized standard EN 13849 (Safety related requirements for control systems).
Warning
All national safety regulations must be fulfilled in connection with installation, start-up and operation of Danfoss PVG-EX.
Furthermore, the requirements of the Declaration of Conformity and national regulations for installations in potentially explosive atmospheres applies as well. Disregarding such regulations involves a risk of serious personal injury or extensive material damage.
Warning
Work in connection with the valve group must be performed only by professionals and qualified persons.
Warning
PVG with non-conductive coating must have preventive protection against electrostatic charge by an earthed metal connection.

Open center PVP with HPCO and PVE PPRV

The Open Center PVP inlet with integrated High Pressure Carry Over (HPCO) functionality is intended for use with fixed displacement pumps in applications where one pump supply for multiple hydraulic subsystems is desired.
The integrated HPCO functionality guides the excess flow of the PVG-EX 32 valve group to the external hydraulic subsystem(s), giving priority to the PVG-EX 32 work functions.
The Open Center PVP with HPCO and PVE PPRV features:
Integrated LS pressure relief valve
•
Threaded ports for P/T/LS/HPCO and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE
•
Optional T0 facility and external T0 port
•
Optional external pilot pressure port (Pp)
•
Only applicable with PVST end plates with separate T-port due to blocked T-lines for HPCO functionality.

PVPC without Check Valve

The PVPC external pilot pressure adapter without check valve is an accessory in the M-port available for PVP inlet modules with integrated pilot pressure reduction valve (PPRV).
The PVPC without check valve cuts off the integrated PPRV to the PVE or PVH/PVHC in the valve group and enables an external pilot pressure supply through the PVPC adapter.

PVP with PVPC without check valve schematic
One application example for the PVPC without check valve is where it is a wanted feature to supply the valve group with oil from a manually operated emergency pump without directing oil flow to the PPRV.
When the main pump is running in its normal operation mode, the oil is directed through the PVPC adapter via the PPRV to the PVE electrical actuators.
When the main pump flow fails, the external shuttle valve ensures that the oil flow from the manually operated emergency pump is used to pilot open the over-center valve and lower the load. The load is only possible to lower when using the mechanical operating lever of the PVG work sections.

When the external solenoid valve is opened, oil from the pressure side of the cylinder is fed via the PVPC through the PPRV to act as the pilot supply for the PVE electrical actuators. This means that it is possible to lower a load by means of the PVE electrical actuators without starting the pump.
The built-in check valve prevents the oil from flowing via the pressure adjustment spool to tank. With the pump functioning normally the external solenoid valve is closed to ensure that the load is not lowered due to the pilot supply oil flow requirement of approximately 1 l/min [0.25 US gal/min].
With a Closed Center PVP the external pilot oil supply can be connected to the pressure gauge connection without the use of a PVPC plug.

Compensated high flow PVBZ with POC and manifold interface

The compensated PVB is intended for controlling a work function where the function behavior in terms of flow and pressures requires independence on the load pressure of other functions used simultaneously.
The integrated LS
relief valve is used to limit the maximum work port build-up on the A/B-ports
A/B
individually.
The bleed-off will prevent pressure build-up on the work ports in neutral.

PVLA Suction Valve

The PVLA valve is an accessory available for PVB basic modules. The PVLA will suck fluid from the tank to the work port to prevent cavitation by the 0.5 bar spring. The
plug will ensure that when using a single acting spool, all flow returning through the work port is led to tank.

PVBS Main Spools

The main spools (PVBS) determine the flow out of the work section or the pressure build up, and are based on a generic platform with a wide selection of additional features, enabling you to tailor the PVBS to suit the demands of any hydraulic system and any function.
The PVBS main spool can be activated in three different ways:
•
Mechanically by a PVM lever
•
Electrically by a PVE/PVHC actuator
•
Hydraulically by a PVH actuator

Flow control spools are for work sections where you want to control the speed (flow) of the work port
Pressure control spools are for work sections where you want to control the power (pressure) of the work port
For more information on where to use flow control or pressure control spools see application guide

Closed neutral position
In neutral position and inside of the deadband area the connection to tank is closed
Throttled open neutral position
Open/closed neutral position (drain)
In neutral position and inside of the deadband area the connection to tank is 10 % of the full flow function
In total neutral position the connection to tank is less than 10 % of the full flow function. But when moving the spool out of neutral position but still within dead band area the connection will close.
