Main characteristics and applications of DIN3352 Gate Valve
1. The DIN Gate Valve has a compact structure, reasonable design, good valve rigidity, smooth channel, and low flow resistance coefficient
2. The sealing surface is made of stainless steel and hard alloy, with a long service life.
3. Adopting flexible graphite filler, reliable sealing, and easy and flexible operation.
4. The driving methods include: electric, pneumatic, gear rotation, structural form: elastic wedge single gate, rigid wedge single gate double gate
5. Water sealed gate valves are widely used in chemical, thermal, power plant and other oil and steam pipelines as the opening and closing device to connect or cut off the medium in the pipeline
