PRODUCT DESCRIPTION
Tecofi EV1141 Brass Solenoid Valve
EV1141 is a Tecofi (France) brass solenoid valve, normally open (NO), pilot operated diaphragm type, BSP female thread, DN 1/2″ to 2″. The valve is open when the coil is de-energised and closes when it is energised. This page covers EV1141 only. EV1140 is in the same family but is normally closed (NC).
Specifications
- Size range: DN 1/2″ to 2″
- Type: normally open (NO) solenoid valve, pilot operated diaphragm valve with low differential pressure, high flow rate, short reaction time
- Body and bonnet: forged brass CW617N; internal parts (tube, plunger, spring) in stainless steel
- Connection: BSP female thread per ISO 228-1
- Seal: NBR (EPDM on request)
- Maximum working pressure: DN 1/2″ to 1″: 20 bar; DN 1″1/4 to 2″: 10 bar
- Maximum working temperature: +90°C with standard NBR; +140°C with EPDM (option)
- Minimum differential pressure: 0.1 bar
- Medium: clear water, hot water, steam, light oils; not for gases and air
- Coil: compatible with most FCDE coils, including ATEX, low power and IP67 types
- Can be mounted in any position; installing with the coil vertical above the body is advised

Difference from EV1140
- State: EV1141 is normally open (NO); EV1140 is normally closed (NC).
- Size range: EV1141 from DN 1/2″ to DN 2″; EV1140 from DN 3/8″ to DN 3″ (it also has DN10, DN65 and DN80).
- Minimum differential pressure: EV1141 is 0.1 bar for every size; EV1140 is 0.2 bar for DN 2″1/2 and 3″.
- Maximum pressure, temperature, body material and seal are the same on both codes (per the datasheets).
Applications
Per the datasheet: water distribution networks, irrigation systems, power generation, plumbing, industrial washing machines, car wash plants, cooling of machine tools, water jet cleaners, autoclaves and similar uses, on clear water, hot water, steam and light oils.
Standards / Certification
BSP thread per ISO 228-1. Body and bonnet in forged brass CW617N (UNI EN 12165:98). Compatible coils include ATEX and IP67 types per the datasheet; state your requirement when asking for a quote.
Installation
Can be mounted in any position; installing with the coil vertical above the body is advised. Not for gases and air. Voltage is chosen through the coil (see the EVBOBINE codes or state the required voltage).

FAQ
Frequently asked questions about EV1141
How does EV1141 differ from EV1140?
EV1141 is normally open (NO), DN 1/2" to 2"; EV1140 is normally closed (NC), DN 3/8" to 3". Both share the brass body, BSP female thread and the same pressure and temperature limits.
What DN sizes does EV1141 come in?
DN15, 20, 25, 32, 40 and 50 (1/2" to 2"), BSP female thread; each size has its own EV1141-00xx Ref. code in the table above.
What medium is EV1141 used for?
Clear water, hot water, steam and light oils. The datasheet states it is not for gases and air.
What pressure and temperature does EV1141 take?
Up to 20 bar for DN 1" and below and 10 bar from DN 1"1/4 to 2"; +90°C with the standard NBR seal, +140°C with optional EPDM; minimum differential pressure 0.1 bar.
What do I send for an EV1141 quote?
Send the valve code, DN, voltage and coil type, medium, temperature, pressure and quantity. CAD replies with a quote within 24 working hours.
