Electric Butterfly Valve
--------------------------------------


Due to continuous history of innovation which is reflected in the high standard and wide range of its products according to ISO 2531 and EN 545, ENC has succeeded to penetrate and keep reasonable share in both local and international markets.

In co-operate with ARABIAN TRADING & ENGINEERING CENTER (ATEC) , representing AUMA Company-Germany, ENC has succeed to produce and supply electric valves to the market which meet client's need to control "the water flow" automatically.

Types of Electric Butterfly Valves according to Operation :

  1. Open/Close Duty :
    Water flow can controlled automatically according to operating order to get complete open or close certain percent.

  2. Modulating Duty :
    To Get :
    - Constant flow rate in pipes.
    - constant water pressure in pipes.

  3. Integral with matic unit

Specifications of Butterfly Electric Valves :

(1) Sizes :
diam. 350 mm to 600 mm

(2) Applied Standards :

Item Standard Specification
Flanges ISO 2531
Pressure test ISO 5208
face to face dimension ISO 5752
Protection of the actuator, IP67/IP68 EN 60529
Motor IEC/VDE 0530


(3) Materials :

Item Standard Specification
Valves Ductile cast iron GGG50
Valves spindle, tube and pin Stainless steel ( 13% Cr. )
Sealing Ring Soft sealing EBDM
Valves coating (internal/exeternal) Epoxy powder
Casing of electric operator GG25


(4) Technical Aspects :


  1. The Actuator is  equipped with two independent adjustable limit switches and two torque switches without any plastic parts or butteries which may need maintenance .
    Connecting wires are sealed in the switch housing actuator. Switches work under mechanical principles.

  2. The Actuator includes a hand wheel marked with two arrows for open/close in case of power failure and adjustment mode.
    The hand wheel will automatically be disengaged when the electric motor is energized .

  3. The Actuator transmits the motion from the motor to the valve through worm gear box principle which provide self lubricant and locking.

  4. The Actuator casing is made of cast iron (GG25) accord. to international specification to be able withstand the operation mechanical stresses.

Fields  of Application

  1. Water & Sewage Net works

  2. Electric Power Stations

  3. Petroleum and Chemical Industries
