Z41H-16C cast steel flange gate valve is one of the most common opening and closing valves, using the up and down work of the gate to connect (fully open) and cut off (fully closed) the fluid medium in the pipeline. Such gate valves are widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipping, metallurgy, energy systems and other body pipelines as a regulator and interceptor.
Product Features
- Low fluid resistance, minimal erosion and abrasion of the sealing surface by the medium (high gate plate opening height).
- Opens with greater force, provides superior sealing performance, allows unrestricted flow direction, prevents turbulence, and maintains pressure.
- Simple in form, easy to manufacture, and suitable for a wide range of applications.
