 产品介绍 
The VG... gas valves with their electrohydraulic SKP... actuators are designed for gas families

These valves are normally closed one-way high-flow type valves.

The swing-type flap has no profile.

The great closing force of the return spring is supported by the prevailing gas pressure.

An AGA... strainer is available as an accessory item.

The valves are supplied without strainer.

I, II, IIIand 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.
