|
The VG... gas valves with their electrohydraulic SKP... actuators are designed for gas families I, II, III and air. They are used primarily in gas-fired combustion plant. The valves open slowly and close rapidly. All types of VG... gas valves can be combined with the available types of actuators. The actuator is fitted to the valve body by means of the 4 screws contained in the terminal compartment. The square flange can be turned in steps of 90°, thus providing 4 different mounting positions. The actuator can be fitted or replaced while the valve is under pressure. Sealing materials are not required.
-
These valves are normally closed one-way disk type valves.
-
Their stem is guided on both sides of the disk, thus ensuring precise alignment of the stroke as well as tight shut-off.
-
The closing force of the return spring is supported by the prevailing gas pressure.
-
The valves are available with profiled or flat disks and with or without stroke limitation.
-
An interchangeable strainer made of stainless steel protects seat and disk as well as downstream controls from dirt. |
