Product Parameter

Structural features:

The national standard stainless steel globe valve adopts two sealing types: flat seal and cone seal, which can be used for medium requirements of different working conditions, with stable sealing performance and long service life. Turn the handwheel counterclockwise to drive the valve stem to drive the valve disc and diaphragm to rise rapidly, opening the channel to allow the medium to pass through smoothly.

Product design and manufacturing standards:

1. Design and manufacture according to GB12235-89

2. The structure length is according to GB12221-89

3. Flange size according to JB/G79-94

4. Valve inspection and test according to GB13927
