The WJ41H/WJ41Y manual corrugated pipe national standard globe valve is suitable for cutting off or connecting the regulating pipeline medium in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with a working pressure of 1.6~4.0 MPa and a working temperature of -29~350 ℃.We use advanced metal corrugated pipe sealing technology to manufacture high-performance metal corrugated pipes. The corrugated pipe sealing globe valve adopts a design of corrugated pipe sealing, completely eliminating the disadvantages of ordinary valve stem packing sealing aging and easy leakage. This not only improves energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment. Widely used in industries such as petrochemicals, chemical fiber textiles, plastic paper making, power steel, printing and dyeing rubber, and food.
Product features:
- Reasonable product structure and reliable sealing
- Sealing surface is welded with Co based hard alloy, which is wear-resistant, corrosion-resistant, with good friction resistance and long service life
- Valve stem quenching and surface nitriding treatment, with good corrosion and friction resistance properties
- The material of parts and the dimensions of flanges and welding ends can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs
- The valve core can be cut off or adjusted according to needs
