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 80079-37:2016 Non-electrical equipment for explosive atmospheres – Non-electrical type of protection constructional safety “c”, control of ignition sources “b”, liquid immersion “k”
•
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.

PVG-EX 32

General information

General description

PVG 32 is a hydraulic load sensing (LS) valve designed to give maximum flexibility. From a simple load sensing directional valve, to an advanced electrically controlled load-independent proportional valve.
The PVG 32 modular system makes it possible to build up a valve group to meet the different functional requirements precisely.
The compact external dimensions of the valve remain unchanged whatever combination is specified. The PVG 32 interfaces to other valve families like PVG 128/256 enabling all machine functions being
controlled from one single valve stack.

Features

Features of the PVG 32 include:
•

‒
•
Good regulation characteristics
•
Energy-saving
•
Up to 12 basic modules per valve group
•
Several types of connection threads
•
Low weight
•
Compact design and installation

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.

Closed center PVPV with PPRV

The Closed Center PVPV inlet with integrated pilot pressure reduction valve (PPRV) is intended for use with variable displacement pumps in applications where a valve group with electro-hydraulic or hydraulically controlled work sections is desired.
The Closed Center PVPV with PPRV features:
Optional shock/anti-cavitation valve facility (PVLP)
•
Threaded ports for P/T/LS and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE or PVH/PVHC
•
