 Suitable for use with gases of gas families I...III

 Gas valves in connection with actuators open slowly and close rapidly

 2-port valves of the normally closed type

 ½“... DN80

 The gas valves are used in combination with the SKPx5 actuators

 As a control valve in connection with SAX31 actuators and AGA60 adapter

(not as a safety shutoff valve)

 As a control valve in conjunction with AGA61, not as a safety shutoff valve

 Supplementary Data Sheets on actuators (see Mechanical design)

The VGx and this Data Sheet are intended for use by OEMs which integrate the

gas valves in their products!

Use The gas valves are used primarily for application at gas-fired combustion plant for gas trains at forced draft burners The gas valve is used as: Shutoff valve (in combination with SKP15) Control valve with shutoff feature (in combination with SKP25, SKP55 or SKP75) As shutoff or control valves in the supply air line of industrial combustion plant with or without heat recovery system - If the gas valves are used with gases other than those of gas families I...

Life cycle The combination gas valve VGx and actuator have a designed lifetime* of Nominal sizes Burner startup cycles 25 DN 200.000 25...80 DN 100.000 80...150 DN 50.000 under use of gases to EN 437 (or DVGW specification G260). This lifetime is based on the endurance tests specified in standard EN 161. A summary of the conditions has been published by the European Control Manufacturers Association (afecor - www.afecor.org).

Flow chart (cont'd) Legend ___ 1) Maximum flow rate (gas valve fully open) The valve curves shown represent gas valves with no strainer. Each strainer reduces the flow rate by about 8% The bold curves represent the recommended pressure drop ranges. Gas valves with higher pressure drops can cause excessive flow noise. Practical experience shows that applications outside the range confined by the bold characteristics could produce significant noise.
