Functioning (see hydraulic scheme)
- The electrically operated valve E2113-06 it is realized to be operated by a three-way solenoid valve 6B (NO) and 6A (NC)
- This valves may be supplied with normally closed de-energized solenoid or with normally open de-energized solenoid valve.
- Furthermore the valve may be manually operated if necessary by the lever placed on the body of solenoid valve (6 A - B).
- When the solenoid control is actuated to open, the main valve will open wide.
- When actuated to close, the main valve close drop tight.
- The pilot control shall be a 3 ways solenoid valve. The solenoid shall operate the main valve directly without auxiliary on/off devices.
- The solenoid valve may be operated by remote devices such as timers, relays, probes etc… Solenoid and valve action shall be specified as either energized to open or energized to close the main valve.

Green area: no danger of cavitation (and therefore no significant wear on the valve)
Red area: notable danger of cavitation (with accelerate wear and damage of the valve)
Installation
Packing and storage
The valves are packed in special cardboard boxes. Outside the carton are clearly pointed out:
- The arrow indicating the position of the valve
- The name of the customer
- The code of the valve
- The number of order confirmation
The valve is protected by two hardening foam cushions, carefully coated by a thermal plate.
This kind of packing if properly stored avoids all the damages originated from transport, unloading, and handling before installation. Avoid storing it under the rain for more than 24 hours!
Open the upper side of the carton and remove the upper cushion. Do not lift the valve by utilizing the pilot, the pilot circuit, or the position indicator.
For any kind of handling we recommend to utilize proper eyebolts.
Installation
The mounting scheme of the valve is shown on the drawing.
If the valve is working as pressure sustaining device in a transport line, it may be recommended to install a by-pass around it, which will allow to put it out of service during some hours for maintenance purpose, without generating problem for the exploitation of the system.
The choice of the proper "by-pass" alternative must be taken considering the following points:
- a- Can the main transport/feeding line be put out of service during some hours (corresponding to the requested time for maintaining the MAIN VALVE), without generating problem for the exploitation of the system? In particular, it must be considered that an empty system may require several hours to be vented properly.
- b- Pressure relief: Has the downstream or upstream zone of the system to be protected against any risk of pressure surge (quick closing of heavy demands, closing time) ?
Should installation require the main valve stem to be horizontal (cover pointed sideways), manufacturer should be consulted concerning valves of DN200 mm and larger.
Note: All sizes on request are available with an additional venting cover device ( venting cock installed at the top of the cover ) to permit a simple escaping of air during the first commissioning.
- Before control valve assembly, make sure that pipeline it is free from foreign matters or any other obstacle. (note: pipeline must be cleaned, possibly, before assembly. For an ideal pipeline cleaning we suggest a 1.5 m/sec speed during several hours!).
- In presence of foreign matters into the fluid it is indispensable to adopt a strainer on valve upstream side.
- Keep free around the valve space enough for operations as maintenance and calibration.
- Set up the valve according to main valve cast arrow indicating flow sense.
- Install the valve so that the FLOW ARROW marked on the valve body matches flow through the line: UPSTREAM → DOWNSTREAM
Start up of an automatic control valve requires that proper procedures be followed. Time must be allowed for the valve to react to adjustments and the system to stabilize. The objective of the following procedure is to bring the valve into service in a controlled manner.
Feed solenoid valve (6) with compatible feeding voltage.
Realize connection to control board (out of our supplied) of solenoid valve (6 A - B) and of closing/opening limit switches (supplied on request) placed on its support (5) (see Q5 13 12 06)
Feed solenoid valve (6) with compatible feeding voltage.
To verify the feeding of solenoid valve check purchasing order and the code reported on main valve body. Its 6th position indicates the type of feeding of the solenoid valve (6). i.e.: E2113N12 = feeding is 220 V-50 Hz.

- Open all ball cocks (3 A B C) (3D CLOSED) of the pilot circuit. Failure to open these ones will prevent the valve from functioning properly.
- TUP - 93 pre-setting: Speed reaction setting screw [RS] it is plugged for this particular application and then its setting it is not requested. opening speed [OS] is already setting = 3 closing speed [CS] is already setting = 3
Initial set-up: see hydraulic scheme
The start-up of an automatic control valve requires that proper procedures be followed. Time must be allowed after each setting, for the valve to react to adjustment and the system to stabilize. The objective is to bring the valve into service in a controlled way.
Remote controlled :
According to the connection realized giving voltage to the solenoid (6A OR B) we have the following operation:
Normally closed valve: NC (6a)
- With de-energized solenoid valve (6A) P (inlet pressure) side is connected to B side (main chamber of 4), R (downstream pressure could be the outlet pressure or with closed 3C and open 3D the atmosphere) side is closed. In this situation the upper chamber of main valve (4) it is connected to the upstream pressure that acts on the diaphragm that makes closing the valve. The closing speed is adjustable with the Tup 93 cock CS between 1 up to 6 max.
- With energized solenoid valve (6A) P side is closed, B side is connected to R side. Main valve (4) opens with the speed regulated on TUP - 93 control unit OS. In this situation the upper chamber of the main valve (4) is connected to the downstream side of the system circuit, from which it is discharged the pressure acting above diaphragm. That consens its opening according to the differential pressure of the valve. For complete opening of main valve also without flow rate, please connect 3D with atmosphere. (3C ball valve must be closed).
Normally open valve: NO (6b)
- With de-energized solenoid valve (6B) P (inlet pressure coming from the TUP) side is closed. The A ( main chamber 4) side is connected with downstream pressure or with closed 3C and open 3D to the atmosphere. In this situation the upper chamber of main valve (4) it is connected to the downstream side of the system circuit, from which it is discharged the pressure acting above diaphragm. That consens its opening according to the differential pressure of the valve. For complete opening of main valve please connect 3D with atmosphere. (3C ball valve must be closed).
- With energized solenoid valve (6B) P side is connected to A, R side is closed. In this situation the upper chamber of main valve (4) it is connected to the upstream pressure that acts on the diaphragm that makes closing the valve.
Local control: manually operated
Manual operation may be realized, in case of feeding drop, by the lead screw placed on the solenoid (6 A - B), body.
To come back at remote control turn off the solenoid screw 90° horizontal.
Commissioning
- 1- Check he setting of the TUP – 93 pos.7) control unit as described above.
- 2- Adjust the solenoid to force the main valve in closed position.
- 3- Open upstream isolation valve SLOWLY of one/two turns maximum, in order to allow a controlled filling of the main valve. Vent air from main valve chamber through the venting cock 5) (top position).
- 4- Tighten venting cock 5) when air is vented. Now the valve it is completely closed.
- 5- Open slowly (two or three turns) downstream valve (if existing one).
- 6- Verify opening and closing speeds energizing and de-energizing solenoid valve (6 A - B), to open and close main valve (4). In case of times incompatibles with working condition, change on the opening [OS] and closing [CS] speed setting on TUP - 93 control unit.
- 7- If existing open completely upstream and downstream valves.
if the opening speed or the closing speed are too fast, please contact our Customer Service, indicating all data as per plastic label on main valve body. Give full detailed information's about working conditions, the type of problem, and report the adjusting values (OS-CS).
Maintenance
Recommended spare parts:
- Full set of gaskets for E2001 main valve
- full set of gaskets for Auxiliary valve F - 22 / 1
The quality of the material used in the manufacture of our valves should produce no wear of the internal components.
However we are recommending:
After 6 months of service :
- Control and clean eventually the TUP - 93 screen Note: an obstructed screen due progressively the valve out of order.
After 12/18 months of service :
- Control and clean the TUP - 93screen.
- Take the main valve apart, by removing first the complete pilot circuit.
- Unscrew the stud nuts and remove the cover and internal diaphragm assembly.
- Check for any eventual damage of the QUAD-RING and the diaphragm.
- Clean thoroughly the internal part of the valve, grease slightly the stem at both guided locations (water grease, non-toxic!!).
- Assemble the main valve and the pilot circuit.
- Put the valve back into service.
This control should then allow to determine the cycle of the requested maintenance, since it is taking into consideration the true service conditions of the valve.
For any further information contact our Customer Service, indicating all data as per plastic label on main valve body. Give full detailed information's about working conditions, the type of problem, and report the adjusting values (OS-CS-RS).
