zLCPV16EKA 230 V Solenoid Valve
zLCPV16EKA 110 V Solenoid Valve
zLCPV16EKA 24 V a.c./d.c. Solenoid Valve
You must use the valves as specified in this manual.
Read this manual before you install and operate the valve. Important safety information is highlighted as WARNING
and CAUTION instructions; you must obey these instructions. The use of WARNINGS and CAUTIONS is defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 Description
The solenoid operated low cost valves are designed for general vacuum use where there is a requirement to open and
close a vacuum line. The vacuum line is opened and closed 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 at 90 degrees to each other and may be mounted for pumping in either
direction.
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.

Installation
C417-51-880 Issue C
3 Installation
3.1 Unpack and inspect
Remove all packing materials and protective covers from the LCPVEKA valve.
If the valve is damaged, notify your supplier and the carrier in writing within three days; state the Item Number of
the valve together with your order number and your 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
Connect the valve to your vacuum system with standard NW coupling components.
To achieve the MTTF stated in Section 2, you must fit the valve so that the actuator is vertical to the valve body.
If you use the valve to vent directly from the atmosphere, we recommend that you fit a filter to the inlet of the valve
to prevent blockage of the valve by dust.
3.3 Electrical connections
Refer to Figure 3 for the item numbers in brackets and use the following procedure to connect the electrical supply
to the valve; ensure that you use a suitable size electrical supply cable (6.5 mm to 13 mm). Refer to Section 2.4.
1. Ensure that the electrical supply corresponds with the voltage stated on the valve label.
2. Undo the four screws (6) and remove the PCB box cover (4) from the valve. (Do not remove electronic device).
3. Unscrew the gland compression screw (8) and detach from the PCB box cover (4).
4. Detach the steel gland compression ring (7) and the rubber cable gland (5) from the PCB box cover (4).
5. Strip back the outer sheath on the three core cable selected to be affixed for a distance of 30 mm and strip the
insulation from each core for a distance of 5 mm.
6. Slide the gland compression screw (8) followed by the steel gland compression ring (7) onto the cable.
WARNING
Take appropriate safety precautions when you install the valve in a system in which dangerous
process substances have been pumped.
WARNING
The valve should be earthed to all connecting pipelines to prevent them becoming hazardous live
in the event of a plasma discharge inside the vacuum system.
WARNING
Ensure that the electrical installation of the LCPVEKA valve conforms with your local and national
safety requirements. It must be connected to a suitable fused and protected electrical supply.

Installation
7. Adjust the inner bore diameter of the rubber cable gland (5) by removing laminated layers until the rubber cable
gland (5) is a sliding fit on the outer cable sheath.
8. Pass the connection cable through the hole in the PCB box cover (4) and attach the wire ends to the terminals.
Earth wire to terminal (1) Neutral wire to terminal (2) and Live wire to terminal (3).
9. Slide the PCB box cover (4) over the PCB and attach using four box retaining screws (6).
10.Slide rubber cable gland (5) and steel gland compression ring (7) down the cable and into the hole in the PCB box
cover (4).
11.Insert gland compression screw (8) into the PCB box cover (4) and tighten to retain cable.

Operation
C417-51-880 Issue C
4 Operation
Once correctly installed the operation of the LCPVEKA valve is dependent only upon the switching of the electrical
supply to the valve.
This range of 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.
5Maintenance
The LCPVEKA valves do not require routine maintenance during their normal operational life and cannot be serviced
by the user. Carry out the following checks when you maintain your vacuum system:
zCheck that the connection to the vacuum system is secure.
zCheck that the electrical connections are secure and that the electrical cable is not damaged.
z
6 Storage and Disposal
6.1 Storage
Place protective covers over the valve ports and store the LCPVEKA 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 from it safely in accordance with all local and national safety and
environmental requirements.

Return the equipment or components for service
Before you send your equipment to us for service or for any other reason, you must send us a
completed Declaration of Contamination of Vacuum Equipment and Components – Form HS2. The
HS2 form tells us if any substances found in the equipment are hazardous, which is important for
the safety of our employees and all other people involved in the service of your equipment. The
hazard information also lets us select the correct procedures to service your equipment.
We provide instructions for completing the form in the Declaration of Contamination of Vacuum
equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
 If a pump is configured to suit the application, make a record of the configuration before
returning the pump. All replacement pumps will be supplied with default factory settings.
 Do not return a pump with accessories fitted. Remove all accessories and retain them for
future use.
 The instruction in the returns procedure to drain all fluids does not apply to the lubricant in
pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/, follow the procedure in
HS1, fill in the electronic HS2 form, print it, sign it, and return the signed copy to Edwards.
Note: If we do not receive a completed HS2 form, we will not accept the return of the
equipment.
