1Introduction
1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the Edwards IPVA10EK air admittance
valve. The valve must be used as specified in this manual.
Read this manual before installing and operating the valve. Important safety information is highlighted as WARNING
instructions; these instructions must be obeyed.
The use of WARNINGS and CAUTIONS are defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
The following warning symbols can be found on this product:
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 Description
The IPVA10EK valve is solenoid-operated and is designed for the automatic admittance of air or vent gas into a
vacuum system. The vacuum system is isolated from atmosphere (or the vent gas supply) by a fluoroelastomer pad
on the base of the valve-plunger which seals against the body of the valve.
The valve has two ports with NW flanges. One of these flanges is used to connect the valve to the vacuum system;
the other flange can be left open to atmosphere or connected to a vent gas supply.
Normally-open and normally-closed versions of the valve with a range of different electrical supplies are available to
suit the application.
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.
Warning - refer to accompanying documentation.
Warning - hot surface.

Installation
C417-60-880 Issue A
3 Installation
3.1 Unpack and inspect
Remove all the packing materials and protective covers and check the IPVA10EK valve. If the valve is damaged, notify
the supplier and carrier in writing within three days; state the Item Number of the valve together with the order
number and the supplier's invoice number. Retain the packing materials for inspection. Do not use the valve if it is
damaged.
If the valve is not to be used immediately, replace the protective covers. Store the valve in suitable conditions, as
described in Section 6.
3.2 Install the valve
CAUTION
The body of the valve has an arrow which indicates the correct direction of gas flow. If the direction of gas flow
is incorrect, the valve may leak.
Connect the valve to the vacuum system (and, if required, to the vent gas supply) with standard NW coupling
components. If the valve is used to vent directly from the atmosphere, Edwards recommend that a filter is fitted to
the inlet of the valve to prevent contamination of the valve through the ingress of dust.
3.3 Electrical connections
Refer to Figure 2 for item numbers in brackets and use the following procedure to connect the electrical supply to
the valve; ensure that a suitably sized electrical supply cable is used (refer to Section 2.3):
1. Ensure the electrical supply corresponds with the voltage stated on the valve label.
2. Gently prise out the connector block (2).
WARNING
Do not operate the IPVA10EK valve in safety critical applications. The IPVA10EK is not intended to
be fail-safe.
WARNING
If the nature of your application requires there to be an electrical connection between the valve
and adjacent pipe-work, the electrical connection should be adequately verified before the system
to which the valve is connected is operated.
WARNING
Take appropriate safety precautions when installing the valve in a system in which dangerous
process substances have been pumped.
WARNING
Ensure that the electrical installation of the IPVA10EK valve conforms with local and national
safety requirements. It must be connected to a suitable fused and protected electrical supply.

Installation
3. Remove the strain-relief nut (6) and sealing gland (5). Pass the electrical supply cable through the strain-relief
nut (6), the sealing gland (5) and into the electrical supply socket (3).
4. Connect the electrical supply cable to the appropriate terminals of the connector block (7, 8, 9) as shown in
Figure 2.
5. Push the connector block (2) back into the electrical supply socket (3), a click should be heard; ensure that it is
orientated correctly so that the sockets mate with the corresponding pins on the valve.
6. Tighten the strain-relief nut (6) and push the electrical supply socket (3) onto the three connector pins on the
valve.
7. Refit the retaining screw (4) and tighten; ensure that there is a slight compression of the sealing gasket (1).

Operation
C417-60-880 Issue A
4 Operation
Once correctly installed, the operation of the IPVA10EK valve is dependent only upon the switching of the electrical
supply to the valve:
Normally-open valves close when the electrical supply to the valve is switched on; the valve opens
automatically when the electrical supply is switched off.
Normally-closed valves open when the electrical supply to the valve is switched on; the valve closes
automatically when the electrical supply is switched off.
WARNING
Do not touch the surface of the valve coil during operation. It may be hot.

Maintenance
5Maintenance
IPVA10EK valves do not require routine maintenance during normal operational life and cannot be serviced by the
user. Carry out the following checks when maintaining the vacuum system:
Check that the connection to the vacuum system (and to the vent gas supply, if fitted) is secure.
Check that the electrical connections are secure and that the electrical cable is not damaged.
WARNING
Do not inhale or touch the breakdown products of fluorinated materials which may be present if
the vacuum system has been heated to 250°C or more. These breakdown products are very
dangerous.

Storage and disposal
C417-60-880 Issue A
6 Storage and disposal
6.1 Storage
Place protective covers over the valve-ports and store the IPVA10EK valve in cool, dry conditions until required for
use. When required, prepare and install the valve as described in Section 3.
6.2 Disposal
Dispose of the valve and any components removed from it safely in accordance with all local and national safety and
environmental requirements.
